We cover announcements from the organiser, the government, Kanagawa Prefecture and Yokohama City, and keep what was announced separate from our take and our tips for visitors.
On 30 October 2026 the GREEN×EXPO Association named the AEON Group a Platinum Partner. Ads will run on screens in about 250 stores, mainly in the Kanto region, and in about 100 AEON Cinemas.
Our take: AEON is the fourth Platinum Partner of the awareness-building project we know of, after the Osada advertising group, Keikyu and JTB, and it adds shop floors and cinemas to the places where the Expo is advertised. Events at AEON Mall are planned, but the malls and dates have not been announced.
On 30 October 2026 Mitsubishi Heavy Industries said it will donate about 20,000 GREEN×EXPO 2027 tickets to three cities near its Kanto sites: Sagamihara, Yamato and Hitachi.
Our take: The number is the same as for Expo 2025 Osaka, about 20,000, but the tickets now go to three cities instead of about 20 municipalities. Last time they were child tickets handed out through local boards of education; this release does not say what type of ticket it is or how residents will receive one.
Water dispenser maker OSG Corporation will hold Sutehaji EXPO 2026 at Pia Arena MM in Yokohama on Thursday 5 November, co-hosted by the GREEN×EXPO Association. Entry is free with advance registration.
Our take: It is on a weekday, but entry is free and the Association's head of PR speaks from 15:35. The organiser says information on drinking water at the GREEN×EXPO 2027 venue will be presented, so there may be news on the refill stations, whose number and locations were not given in September.
On 30 October 2026 Yokohama City said it signed a sponsorship contract with LIXIL Renewal on 16 October. The company will lend its PV roller screen, which generates power on the inside of a window, and install it in the pavilion.
Our take: By the city's own press list, this is the 29th sponsorship of the city pavilion since Tokyo Gas on 21 July. It is the second exhibit that generates power at a window, after YKK AP's solar inner window in August; this time the power comes from a screen pulled down inside the window, not from the glass.
The Flower Life Promotion Council held its third "EXPO Sakaba" evening in Ginza on 24 October, with the Expo Association’s Ryuichi Wakisaka on the venue. Sessions four and five follow on 20 Nov and 18 Dec.
Our take: This is run by a flower-industry association, not by the Expo Association, though Ryuichi Wakisaka of the Association spoke at the third session. For Expo history, the 18 December session with Professor Tomoyuki Okada of Kansai University is the one to pick.
InterContinental Yokohama Pier 8 will serve "Strawberry Garden", a strawberry afternoon tea with preserved-flower table settings, from 1 December 2026 to 28 February 2027 for 6,500 yen.
Our take: The hotel links the theme to interest in flowers ahead of GREEN×EXPO 2027, but the tea ends on 28 February, before the 19 March opening. It is a seasonal hotel tea with flowers on the table, not an official Expo event.
The MLIT announced on 29 October 2026 that up to 50 Nihon Kotsu JPN TAXI cabs wrapped with Tunku Tunku will run in Tokyo's 23 wards, Musashino and Mitaka. They cannot be booked.
Our take: These cabs run in Tokyo, not Yokohama, putting the mascot on Tokyo's streets in addition to the host city. You cannot request one; whether you ride one is down to luck at a rank or on the street.
Yokohama City will take booth applications from 2 Nov to 28 Dec for the Yokohama 18 Collection, a ward food and performance event at the Expo's Event Plaza from 21 to 29 July 2027.
Our take: For visitors, what matters is that local food and performances from Yokohama's 18 wards will fill the venue from 21 to 29 July. Who takes part will not be known until selection results in February. The venue, called the Main Event Plaza (provisional name) in September, is now listed as the Event Plaza.
Osaka confectioner Amidaike Daikoku will sell a Tunku Tunku drawstring pouch holding seven chocolate crunch bars from 28 October 2026 at some official expo stores and the official online store.
Our take: This is Amidaike Daikoku's second official licensed product, two weeks after its cookies. The shops, the last sales day of 18 March (the day before the opening) and the 180-day best-before period are all the same; the difference is the pouch you keep afterwards.
The expo's licensing office and Felissimo announced Lisa and Gaspard × Tunku Tunku goods on 28 October 2026: four items on sale now and a clear tote bag in early November.
Our take: One of the shops, the EXPO 2027 Official Pop-up Store, opened on 20 October in ecute Ueno, inside the ticket gates of JR Ueno Station. Entering from outside the station needs an admission ticket or the Touch de Ekinaka IC card entry service.
Suntory Holdings announced on 28 October 2026 that it will sponsor SUNTORY GREEN GO ROUND, a 1,650 m² showcase on water, energy and farming in the Farm & Food Village at GREEN×EXPO 2027.
Our take: The solar-panelled vending machines planned inside and outside the showcase covered about 45% of their own power in a year-long trial in a Sagamihara park, Suntory said the same day. In summer the figure fell to about 30%, and the later months of the expo fall in that season.
Sakata Seed will sell a mini tomato and a flower seed-ball mix in packets designed by students in a GREEN×EXPO 2027 contest, by mail order as spring 2027 limited editions.
Our take: The tomato costs 495 yen and the seed balls 550 yen. The seed-ball mix is sown in April to June and flowers in July to October, so seeds sown in spring will bloom at home during the expo's summer.
Yokohama City signed sponsorships for its Tsunagu Yokohama Pavilion with Takenaka (26 Oct), lending exhibits on living on the Moon, and JGC Holdings (27 Oct), on SAF and clothing recycling.
Our take: These follow Obayashi on 20 October and are the 27th and 28th by our count. The domestic SAF that JGC will show is also the fuel planned for the Blue Impulse flyover on opening day, so it turns up both in the sky and in the pavilion.
The GREEN×EXPO association says Queen's Square Yokohama will host an 8.7 m expo-themed Christmas tree from 9 November to 25 December, with expo graphics in the building until March.
Our take: The tree comes down on 25 December, but the expo graphics on the glass walls inside are planned to stay until 31 March 2027, past the 19 March opening. The lighting ceremony on 9 November starts at 18:00 and is free; numbered tickets are handed out from 15:00.
Yokohama City said on 26 October 2026 that Minna no Koe, a fertilizer containing phosphorus recovered from sewage sludge, will be used in planting at GREEN×EXPO 2027.
Our take: The GREEN×EXPO association tested it in planting trials at the site before deciding to use it. The same fertilizer is sold over the counter at JA Yokohama's Mercato farm shops, so you can use what feeds the expo's flowers in your own garden.
On 23 October 2026 Kanagawa Prefecture published the dates of the rotating 'spot exhibits' inside its Vibrant INOCHI Forest Kanagawa pavilion: 29 by prefectural bodies and schools, 22 by municipalities.
Our take: Two spaces of about 25 square metres are shared out a few days at a time. Each exhibit runs for only three to nine days, so if you want to see a particular town, pick your Expo day to match its dates. Yokohama, Sagamihara and Yokosuka are the three cities missing from the list.
On 23 October 2026 the Expo 2027 master licensing office announced four Tunku Tunku items with JOURNAL STANDARD relume, drawn by artist kurry, on sale at BAYCREW'S FESTIVAL OSAKA on 24 and 25 October.
Our take: Tunku Tunku licensed goods have become clothing from a BAYCREW'S brand. The release came out the day before sales began, and the only outlet it named was a two-day festival in Osaka. As of 26 October neither the release nor the licensing office's news list mentions online or store sales afterwards.
On 22 October 2026 the GREEN×EXPO association said Pasona is hiring staff for the area of individual national pavilions (International Garden Type). Applications close 10 November (planned).
Our take: The 21 October release named no contract; now the association says Pasona hires for the national pavilion area it has contracted out. Pasona's page gives pay and headcounts: about 90 people in three roles, working the full run from 19 March to 26 September, with French, Spanish and Portuguese asked for alongside English.
On 21 October 2026 Pasona announced it will recruit 220 staff for several contracted GREEN×EXPO 2027 operations, with three briefing sessions at Pasona Yokohama from 23 October.
Our take: A notice for people who want to work at the Expo, not for visitors. Roles span attendants, directors, pavilion operations and language support, but the release does not say which contracts Pasona holds, and briefings are only for registered, screened applicants. The third date reads 7 or 17 November. On 22 October the association said one contract is the national pavilion area.
On 21 October 2026 Pia announced the 'Tunku Tunku & Myaku-Myaku Smartphone Shoulder BOOK', on sale 29 October for 3,300 yen: an 8-page A4 mook with an embroidered black shoulder bag.
Our take: The 8-page book is the wrapper; the embroidered shoulder bag is the product. Myaku-Myaku passing a flower baton to Tunku Tunku repeats the 'handover' motif of September's gold coin, this time at 3,300 yen and sold through bookshops nationwide rather than official stores and events.
On 21 October 2026 the GREEN×EXPO Association published ticket sales as of 18 October: 2,899,344 in total, up 289,782 from 18 September. Season passes rose to 25,131.
Our take: The month after convenience-store sales and timed-entry booking began added 289,782 tickets, about 9,700 a day, slower than the roughly 14,000 a day averaged over the previous six months. Season passes grew 36% to 25,131. Whether RING PASS winners are included is not disclosed.
On 20 October 2026 the Fry to Fly Project, run by JGC Holdings, announced it will collect used cooking oil from 9 December 2026 to 28 February 2027 as feedstock for domestic SAF planned for the Blue Impulse display flight at the opening of GREEN×EXPO 2027.
Our take: Oil from a home deep fryer becomes part of the fuel for the jets flying over the venue on opening day. Collection points are unknown until 9 December, and the Air Self-Defense Force's schedule gives only the date, not the time or route of the flight.
On 20 October 2026 Yokohama City announced a sponsorship contract with Obayashi Corporation for its GREEN×EXPO 2027 pavilion, lending exhibits on a future where space is part of daily life.
Our take: This is the first sponsorship announced for the city pavilion since Kajima on 28 September, and the 26th since Tokyo Gas on 21 July by the city's own press list. It is the second space-themed one after IHI's Epsilon rocket. Whether the exhibit is a model or a film is not stated.
On 19 October 2026 the organiser named Alpha Locker System for the coin lockers outside the gate and Yamato Transport for luggage storage and delivery.
Our take: Suitcases are not allowed inside the Expo, so where to leave them before entry matters. Under the organiser's tender plan, the coin lockers sit outside the gate, number 600 or more and open at 9:00. Prices and the final locker count have not been published.
On 19 October 2026 the organiser adopted detailed plans for fire and disaster response, medical care and hygiene, fixing first-aid posts, AEDs and lightning shelter.
Our take: In lightning, visitors will be sent indoors or to areas with lightning shelters, and wooded areas will be cleared first. The plans still give no threshold for stopping outdoor events. Of the three first-aid posts, only the two clinics stay open after 17:00.
On 19 October 2026 the Expo 2027 licensing office released a Tunku Tunku promotion song on its X and Instagram. It will play in official stores and at meet-and-greets.
Our take: The song comes from the office that runs official merchandise, and its subject is Tunku Tunku asking listeners to buy. It is on the office's X and Instagram for now and will play in official stores across Japan. The singer and songwriters have not been named.
On 16 October 2026 Dai-ichi Life announced the winner of its 'The Garden of Life' award. Team LIFE LINE will build three gardens inside the GREEN×EXPO 2027 site, with construction and upkeep funded.
Our take: One more garden is now confirmed for the expo site. Because it is built mainly from native perennials, it should look quite different between the spring opening and the autumn close. Its location within the site and the dates of the theatre performances have not been announced.
On 16 October 2026 the GREEN×EXPO Association updated its list of participants. China was the only addition, taking the total to 75 countries and five international organisations.
Our take: China hosted an A1-class horticultural expo of its own in Beijing in 2019. What we know now is only that it has announced participation; no participation contract or exhibit plan has been announced yet.
GREEN×EXPO 2027 will run a booth at the Green Good Market at Minami-machida Grandberry Park on 7 and 8 November 2026, selling entry tickets and official goods and holding free bouquet-making sessions.
Our take: On 7 and 8 November there is a booth selling Expo tickets and official goods right by Minami-machida Grandberry Park Station, one of the four shuttle-bus stations. The bouquet sessions take 36 people a day, first come first served, with no booking.
Kanagawa Prefecture will run GREEN×EXPO 2027 booths at the Sagamihara Linear Festa on 24 and 25 October, the Minna no Kawasaki Festival on 1 November and the windsurfing World Cup at Tsukui beach on 3 November 2026.
Our take: After Zushi on 18 October, the prefecture's booth visits three events in eleven days. The Linear Festa is in a construction site three minutes' walk from Hashimoto Station, and the Kawasaki festival fills the streets in front of Kawasaki Station. None of the notices says what the booth will offer.
LET'S EXPO, which pushed wheelchairs and guided visitors at Expo 2025, was named in the 2026 Good Design Best 100 and won a Good Focus Award. It plans mobility support inside GREEN×EXPO 2027.
Our take: LET'S EXPO, which pushed wheelchairs and walked with visitors at Expo 2025, has been recognised by the Good Design Award. It plans to help people get round the GREEN×EXPO 2027 site too, but how to apply and what it costs are not yet out.
On 15 October 2026 NTT East announced the "well" project, in which schools, local groups, companies and staff grow flowers and bring them in turn to the flowerbed of its GREEN×EXPO 2027 pavilion.
Our take: The NTT EAST Pavilion's flowerbed will be filled with flowers grown by Yokohama secondary-school pupils and children at a nursery near the site, brought in over time. How often the planting changes is not yet announced, but March and September should look different.
On 15 October 2026 Sotetsu announced that its new 13000 series train, in service since 30 March, has won a 2026 Good Design Award. A car of the same model will be displayed at SOTETSU PARK at GREEN×EXPO 2027.
Our take: Only one eight-car 13000 series train is in service, and it runs only on Sotetsu's own lines, so catching it is luck. At GREEN×EXPO 2027, SOTETSU PARK will display a lead car of the same design, where the headlight details the jury praised can be seen up close.
Amidaike Daikoku's cup of 17 Tunku Tunku print cookies, 1,000 yen, is on sale at EXPO 2027 Official Stores from 14 October 2026 to 18 March 2027.
Our take: Seventeen cookies printed with Tunku Tunku, plus a sticker, for 1,000 yen. Sales end on 18 March 2027, the day before the Expo opens. In Yokohama, two Maruzen bookshops carry them, and more stores may be added.
Asuka III's early-summer 2027 cruises from Yokohama (5 June to 8 July) come with GREEN×EXPO 2027 tickets. Bookings open 11 November 2026.
Our take: Yokohama-based Asuka III has announced 32 cruises for April to October 2027, overlapping the Expo. Passengers on early-summer cruises (departing 5 June to 8 July) that start and end in Yokohama get Expo tickets. Bookings open 11 November at 10:30. Fares and ticket type are not given.
Outdoor ad firm Hit is now a GREEN×EXPO 2027 Silver Partner, showing Expo videos on its Shibuya screen and Shuto Expressway LED boards.
Our take: Outdoor advertising company Hit is now a Silver Partner of the Expo, showing the Association's promotional video on its Shibuya screen and on Shuto Expressway LED boards. How long, how often and which expressway boards have not been announced.
Yamashita Park's skating rink and flower-and-light displays run 5 December 2026 to 28 February 2027, themed on next spring's GREEN×EXPO 2027.
Our take: The winter skating rink at Yamashita Park opens from 5 December 2026 to 28 February 2027. Entry is free; the rink costs 1,200 yen for adults. It closes 19 days before the Expo opens, and this year adds flowers and light to the usual music and skating.
Yokohama is recruiting children in grades 4 to 9 to interview staff behind the city's Expo pavilion and present to peers. Apply by 1 November 2026.
Our take: Yokohama City wants children to report on its own Expo exhibits. Groups of three to six children in grades 4 to 9 who live in the city attend three Saturdays between November and February. Applications close on 1 November, with a lottery if oversubscribed.
On 9 October 2026 Meiji Holdings opened a site for ORAGA VILLAGE, its themed shop in the Farm & Food Village at GREEN×EXPO 2027, with a new logo and the latest exterior image.
Our take: Visitors will walk in through the mouth of a giant Karl Ojisan. The corn planted beside the entrance may be harvested as early as July, so the entrance will look different depending on the month you go. Admission and reservations have not been announced.
The operator of null²ⁿ, Yoichi Ochiai's permanent theatre in Yokohama Landmark Plaza, announced on 9 October 2026 that it opens on 14 October and revealed the gate and five areas inside.
Our take: What fills the roughly 60-minute visit is out for the first time. After the gate come five areas: the second is a completely dark room with sound only, the third shows about 170 human inventions, and the last, a bridge, has a photo moment. The release does not say which area is the LED theatre. It opened as planned on 14 October 2026.
Sotetsu Group will run a hands-on dairy day at a farm in Seya Ward, Yokohama, on 7 November 2026, as a lead-up event to GREEN×EXPO 2027. Entry is by lottery until 25 October.
Our take: At most 100 people can take part across the two sessions, in groups of up to four, chosen by lottery. To protect the cows, anyone who has travelled abroad on or after 24 October cannot join. The animal sketches children draw at the farm will be shown on the website for SOTETSU PARK, the group's exhibit at the Expo.
The GREEN×EXPO Association will sell early-bird paper one-day tickets (5,000 yen for adults) at four events in October, with a help desk for bookings.
Our take: The adult price of 5,000 yen is the early-bird 4,900 yen plus the 100 yen paper-ticket charge, the same as ordering a paper ticket on the official site. Staff at the help desk will not book for you. They guide you through the steps on your own phone, so bring it.
The Expo association said on 6 October 2026 that the BIE is taking applications for its Cosmos Prize for Expo 2027 until 20 November. One project wins 20,000 euros.
Our take: The award ceremony is on 25 September 2027, the day before the Expo closes. What matters to visitors is that shortlisted projects and their results will be exhibited inside the site. The notice does not say how many will be shortlisted, or where and when they will be shown.
Fukuoka Prefecture said on 6 October 2026 that its farm, forestry and fisheries festival runs on 31 October and 1 November in Tenjin. Tunku Tunku appears on 31 October.
Our take: Tunku Tunku comes on Saturday 31 October only, and the release gives no time or spot inside the park. The festival has a photo spot and bouquet-making with Fukuoka flowers. Fukuoka is one of the prefectures with a flower and green exhibit at the Expo.
Kanagawa Prefecture said on 6 October 2026 who will make parts of the outdoor garden at its GREEN×EXPO 2027 pavilion: two cities, a Kamakura group, farm co-ops and five schools.
Our take: Each part of the garden now has a named maker. Yokosuka shows the sea around Sarushima island, Atsugi shows its river fish and fireworks, and a group of Kamakura shrines and temples builds a Japanese garden. The prefecture says plants will be changed through the season, but gives no dates for any part.
The Expo association said on 6 October 2026 that an official store opens on 9 October inside Maruzen & Junkudo at Shin-Shizuoka Cenova, with three photo sessions that day.
Our take: The opening-day photo sessions take 60 groups in total. Numbered tickets are handed out from 10:00 to people who spend 1,000 yen or more on official goods in the store, and the first session starts at noon. The release gives no closing date for the store.
On 5 October 2026 the Nippon Flower Designers' Association said its 2027 awards show is planned for GREEN×EXPO 2027, 24 April to 2 May. Entries close 15 January.
Our take: The nine-day show changes every three days: dresses and bouquets on 24 to 26 April, arrangements on 27 to 29 April, and work by students and children from 30 April to 2 May. Visitors can pick a day by what they want to see. The release does not say when the public making sessions take place.
Kanagawa Prefecture posted on 2 October 2026 that it will have a GREEN×EXPO 2027 booth at the 48th Zushi Citizens' Festival on 18 October, 10:00 to 15:00. There is no parking.
Our take: The prefecture's booth follows its stops at the Vietnam Festa, the Fujisawa festival and Shibusai on 4 October. Zushi's own page does not mention the Expo booth, so what it will offer is unknown. There is no parking, and a temporary shuttle bus from JR Zushi Station is planned.
The GREEN×EXPO Association announced on 1 October 2026 that it signed an official participation contract with Lebanon on 8 September. All five Middle Eastern participants have now signed.
Our take: The contract was signed on 8 September and announced more than three weeks later. All five Middle Eastern participants have now signed. Lebanon's exhibit has not been announced, but its national day is scheduled for 12 April 2027.
Japan's agriculture ministry will run GREEN×EXPO 2027 booths at nine food and farming events from 3 October to 15 November 2026. The Tunku Tunku costume appears only in Mito on 12 October.
Our take: Of the nine events, only Mito on 12 October has the Tunku Tunku costume; four others show a figure. Official goods are displayed but not sold. The booths give people around Tokyo several chances this autumn to learn the expo layout before it opens.
On 1 October 2026 the organiser reported on three summer safety meetings covering a command centre, a draft lightning evacuation plan and on-site medical care.
Our take: The lightning evacuation plan is still a draft and its text has not been published. The organiser's own table shows Yokohama's thunder days cluster in July to September: 34 of 52 in 2024. How visitors are guided indoors and how many aid stations there will be are left to the implementation plans due around autumn 2026. Update: the plans were adopted on 19 October.
On 30 September 2026 the GREEN×EXPO Association began streaming Let's Green Online, free videos on the environment and the Expo. Two videos are up; more than 20 are planned.
Our take: The Association's own videos now show what is on the site before you go. The introductory guide covers the Theme Pavilion and corporate exhibits, useful when planning a route. It is in Japanese for now, with English planned.
From 1 October to 30 November 2026, Meiji and TOPPAN collect used Meiji Bulgaria Yogurt cups at 13 AEON stores in Yokohama. The cups become goods sold at Meiji's GREEN×EXPO 2027 site.
Our take: A washed yogurt cup dropped in a box at a local AEON becomes material for goods sold at the Expo next year. What the goods will be, their price and when they go on sale are not yet announced.
Yokohama City will hold more workshops in October 2026 to make decorations for its Expo pavilion: colouring at Shin-Yokohama Station on 17–18 October, and sewing and sign painting at City Hall on 25 October.
Our take: Children's drawings of Yokohama wildlife will hang in the city's pavilion next year as mobiles. On 25 October at City Hall, visitors can also paint the YOKOHAMA sign for the pavilion's east wall. No booking is needed.
On 29 September 2026 Yokohama City named its pavilion Tsunagu Yokohama-kan, set dates for two city-run festivals in 2027, and showed a direct bus route from Sakuragicho and the waterfront to the venue.
Our take: The direct bus route is a list of Minato Mirai hotels, Red Brick Warehouse, Chinatown and Hotel New Grand, so it looks aimed at visitors staying in central Yokohama. Times and fares are not out yet, and those are what will decide where to stay.
From October 2026, 31 municipalities in Kanagawa will offer GREEN×EXPO 2027 one-day tickets as thank-you gifts for furusato nozei (hometown tax) donations, joining Yokohama, which started in April.
Our take: Besides Yokohama, 31 more municipalities in Kanagawa will offer an Expo one-day ticket as a furusato nozei gift, starting one by one from October. Each sets its own donation amount, so the prefecture's release gives none. You cannot receive a gift from the municipality you live in.
On 28 September 2026, Imperial Enterprise began selling a pure gold coin of Myaku-Myaku handing a baton to Tunku Tunku by mail order. 260 pieces, 659,780 yen, delivery from late February 2027.
Our take: About 7.77 g of pure gold for 659,780 yen including tax, or roughly 85,000 yen per gram. That is a little more per gram than the Tunku Tunku koban and medal at Yokohama Takashimaya, and it is the only one of them with Myaku-Myaku. Delivery is planned from late February 2027, before the Expo opens.
With a contract signed with a Kajima-led group on 28 September 2026, the City of Yokohama's pavilion at GREEN×EXPO 2027 has 18 sponsors since 13 August, most showing energy and recycling technology.
Our take: Yokohama's pavilion now has 18 sponsors, mostly showing technology such as power-generating windows and floating wind turbines. Exhibit locations, opening dates and booking rules have not been announced.
On 25 September 2026 JVCKENWOOD signed a sponsorship contract with Yokohama City to show a vibration-powered generator, developed with Kyoto University, in the city's pavilion.
Our take: Yokohama City's pavilion gains an exhibit from a company headquartered in the city's Kanagawa-ku. Press a switch, the device shakes, and the electricity it makes lights up a model of the Yokohama skyline. Where in the pavilion it will sit, and when it opens, are not in the announcement.
Cubic Plaza Shin-Yokohama, at JR Shin-Yokohama Station, holds a Flower Fes from 1 October to 12 November 2026. Spend 2,000 yen and spin for a pair of GREEN×EXPO 2027 tickets.
Our take: A shopping receipt at the mall attached to the Shinkansen station might turn into a pair of Expo tickets. Two hundred people a day can spin, and 50 of them win the pair, so one in four. Which ticket type it is, when it is valid and how timed-entry booking works are not in the announcement.
On 25 September 2026 the GREEN×EXPO Association published ticket sales as of 18 September: 2,609,562 in total, of which 2,582,050 are early-bird one-day tickets.
Our take: On 18 September, the day convenience-store sales and timed-entry booking began, 99% of the 2.6 million tickets were early-bird one-day tickets: a quarter of the 10 million paid visitors the Association expects, six months before opening. The split between individuals and corporate bulk buyers is not disclosed.
Daiwa House said on 24 September 2026 it will test power generation from food-waste biomethanol during GREEN×EXPO 2027, supplying its Village pavilion.
Our take: Daiwa House plans to run the cooling-air equipment in its group pavilion on power generated from biomethanol, part of it made from food waste. What visitors will feel is the cool air. Whether the generating equipment will be on show has not been announced.
A free talk and garden tour at Umekoji Park in Kyoto on 24 October 2026 features Toshihiro Inoue, a director for the Japanese government's outdoor garden at GREEN×EXPO 2027.
Our take: A free chance to hear, before opening, from a garden maker building the Japanese government's garden for the Expo. You can join online, and places are first come, first served. The release says Sunday, but 24 October is a Saturday.
The Mitsubishi group's Expo committee revealed on 24 September 2026 that its GREEN×EXPO 2027 pavilion will be a ride through sea, land and sky.
Our take: The Mitsubishi Minna no Miraikan will be a ride that carries visitors through film, sound and light. How many people each ride takes, how long it lasts and whether booking is needed, the things that decide waiting times, have not been announced.
Waterstand, a Saitama-based water-dispenser rental firm, said on 24 September 2026 it will provide refill stations at the venue as a bronze partner in the Expo's heat-measures project.
Our take: The venue will have stations where you can refill your own bottle. If you plan a summer visit, that is one more reason to bring one. Where the stations will be, how many there will be, when they run and whether they are free have not been announced.
A flower industry association announced on 23 September 2026 a second charity salon at ROSE GALLERY Ginza on 26 September: violin, talks and open discussion. ¥10,000, booking via Peatix.
Our take: This is not an Association event. It is run by a flower industry body and a florist that had a Noto recovery stall at Expo 2025 Osaka. The second half is open conversation, so it is not a briefing on the venue. The ¥10,000 includes support for Kumamoto growers.
On 23 September 2026 the organiser apologised after the four-station shuttle bus booking site sent one email many times over on 20 September. Fixed that day; no data leaked.
Our take: The email itself was real. 20 September is exactly 180 days before opening day, when payment opened for provisional bookings on 19 March. Your booking is safe, but it lapses if unpaid, so check its status on the booking site.
Takashimaya will sell a 24-karat Tunku Tunku koban (1.32 million yen) and medal (1.232 million yen), official GREEN×EXPO 2027 licensed goods, at a gold fair in Yokohama from 30 September to 5 October 2026.
Our take: A pure gold Tunku Tunku koban of about 17 g at 1,320,000 yen and a medal of about 15 g at 1,232,000 yen (planned prices), sold at a six-day fair at Yokohama Takashimaya. Quantities and sales method are not stated.
Sustainable Pavilion 2025 unveiled the design of its triple pin badge, the ticket perk for null²ⁿ, the permanent theatre opening 14 October in Yokohama Landmark Plaza.
Our take: One month before its 14 October opening, null²ⁿ revealed the design of its ticket perk, the original triple pin badge linking null², null²ⁿ and null⁴ in black-and-silver metal. An upgrade route now lets holders of a regular ticket add the badge later.
GREEN×EXPO 2027's official pop-up stores are opening at 157 Cainz stores nationwide from September 2026, where pre-sale tickets are also sold.
Our take: Official merchandise stores are spreading to 157 Cainz branches nationwide, where pre-sale Expo tickets are sold too. At the new Hands Shinjuku branch, opening 26 September, spending 3,000 yen or more on official goods that day gets you into a Tunku Tunku photo session.
Yokohama's tourism bureau is launching EXPO Mikke! on 19 September 2026, a site collecting city-wide events, plus new social accounts and a follow campaign.
Our take: The Yokohama City Tourism Association (our rendering of the Japanese name) and the city are launching EXPO Mikke! at 10:00 on 19 September, a site collecting events across Yokohama. Listed events must take an action linked to the planet's future, such as environmental work or local produce. The launch follow campaign runs through 12 October.
Kanagawa Prefecture will pair a high-school flower performance with GREEN×EXPO 2027 at a craft expo on 7 November 2026, and has named six Touken Ranbu ONLINE characters for a tie-in gallery.
Our take: The GREEN×EXPO 2027 tie-in is a flower-arranging performance by high-school students, 14:30-15:00 on 7 November, on a craft expo's main stage in Yokohama. Six Touken Ranbu ONLINE characters and a key visual for a tie-in gallery are set, but the goods and displays are not yet announced.
The GREEN×EXPO 2027 association joined the Kyoto Tamba green fair on 18 September 2026 with a Kengo Kuma monument that began in Kawasaki in 2024 and will later stand at the Expo venue.
Our take: The association joined the National Urban Greening Fair that opened in Kameoka, Kyoto, on 18 September, alongside Yokohama City and Kanagawa Prefecture. Its centrepiece is a Kengo Kuma monument that has travelled from Kawasaki (2024) through Gifu to Kyoto, and is due to stand at the Expo venue itself next.
On 18 September 2026 Japan's agriculture ministry began recruiting restaurants that serve Japanese produce and edible flowers as GREEN×EXPO 2027 supporter shops.
Our take: The Ministry of Agriculture, Forestry and Fisheries will list restaurants that back the Expo on a dedicated website. What visitors get is that list, plus special menus at a fair around January 2027. How many shops will join, and where the website will be, have not been announced.
Kanagawa Prefecture will hold the national selection final of the high-school flower-arranging battle inside the GREEN×EXPO 2027 site on 30 April 2027, with 15 schools given five minutes each.
Our take: Few events during the run have a fixed date yet; this one does. 30 April 2027 is the Friday after Showa Day, in the middle of Japan's spring holiday week. The start time is still being set, and the location within the site was not given.
JR East Cross Station is running a campaign from 21 September to 18 October 2026. Each purchase with a registered Suica offsets 30 yen of carbon, and spending 500 yen in total enters a draw that includes 10 GREEN×EXPO 2027 tickets.
Our take: Spend 500 yen or more in total with a registered Suica at NewDays, ecute and other station shops by 18 October to enter a draw that includes 10 Expo admission tickets. You must enter on the campaign site first, and winners book their own entry time.
Kanagawa Prefecture will run a GREEN×EXPO 2027 booth at the third Shibusai festival in Yamato on Sunday 4 October 2026, in the plazas on both sides of Kozashibuya Station.
Our take: After Vietnam Festa and the Fujisawa festival in September, the prefecture's booth moves to Yamato, the city next door to the Expo site. Neither the prefecture nor the festival says what the booth will offer, so treat it as a stop on a day out.
Sotetsu Building Management will extend its Green Action Program to 12 shopping centres along its lines from 1 October 2026, running until 30 September 2027, just after GREEN×EXPO 2027 closes.
Our take: Twelve centres now, including the Sotetsu Life at Mitsukyo, one of the stations where the Expo shuttle buses start. The scheme runs to 30 September 2027, four days after the Expo closes: the whole run fits inside it. On 6 October Sotetsu said one of the twelve, Sotetsu Life Sagamino, will close in late January 2027.
Yokohama's Economic Affairs Bureau has named the six startups that will build hands-on exhibits inside the city's pavilion at GREEN×EXPO 2027, covering space, quantum computing, energy, recycling, food and manufacturing.
Our take: Satellite launches and quantum computing, both turned into games you play. All six firms belong to the city's tech startup base, TECH HUB YOKOHAMA. When the pavilion opens, and whether entry needs a booking, was not announced.
Macnica outlined its MACNICA Green Tech Messe pavilion on 16 September 2026: two exhibit zones, and self-driving electric buses to carry visitors around the site.
Our take: The exhibits themselves are still unannounced. The concrete news is the self-driving electric bus: the Expo area is about 80 hectares, so its route, stops and fare will shape how people get around the site.
The GREEN×EXPO Association's report on its six-months-out press event, where five special supporters each named the time of year they would visit.
Our take: The five picks run from March to September. One visit in each of the four periods plus one more comes to 27,500 yen in one-day tickets, about the price of the 28,000 yen season pass. The bloom calendar shown at the event is not in the release.
On 15 September 2026 the GREEN×EXPO Association published a first list of events for the 192 days: Nebuta floats, a musical, National Days and monthly highlights.
Our take: Besides monthly highlights, the attachments give dates for individual events and for 59 National Days, so you can now choose a day as well as a month. Nebuta and musical dates are still being arranged. (Corrected 16 September: we first wrote that dates went down to the month only.)
On 15 September 2026 the GREEN×EXPO Association named its three pavilions NEKKO, IROHA-GARDEN and HANAMEGURI, and revealed the six zones inside NEKKO.
Our take: The three Association-run pavilions now have names, and they will appear on the site map and signs. Inside NEKKO the exhibit that stands out is the real roots of the Miracle Pine of Rikuzentakata, which survived the 2011 tsunami. Whether NEKKO will need an exhibit reservation is still not stated.
On 15 September 2026 JFTD Hana Cupid, a network of about 4,000 florists, announced a nine-day exhibit at GREEN×EXPO 2027, 10 to 18 April 2027, with a floristry contest.
Our take: The exhibit runs 10 to 18 April, three weeks after opening, one nine-day slot of the short-term flower and green exhibits. The contest to name Japan's best florist can only be seen in those nine days, which makes it easy to plan around. Location and how to watch the contest are not stated.
On 15 September 2026 the builders of the indoor hall HANAMEGURI gave exhibitor numbers and dates: 21 season-long and 227 nine-day exhibitors, facade done by end of September.
Our take: With 227 exhibitors rotating every nine days, roughly ten show at a time and the line-up changes more than 20 times over the season. Two visits will not show the same thing. Season-long exhibitors are up by two from our July list, and the lattice facade is on its third Expo after Dubai and Osaka.
Mizuno is taking advance orders for 17 Tunku Tunku items, including shoes, T-shirts and training goods, online and at two of its stores until 30 September 2026, with delivery planned for March 2027.
Our take: To have Tunku Tunku shoes or clothes before the Expo opens, order from Mizuno online or at two of its stores by Wednesday 30 September, for delivery in March 2027. Prices have not been published.
On 15 September 2026 the GREEN×EXPO Association revealed Mika Ninagawa's two Expo works: the TAISEI GREEN TERRACE and a projection show on a former powder magazine.
Our take: The terrace is about 4.5 metres high with a 90-metre ramp: less a lookout than a walk over photographed and living flowers. The night projection on the former powder magazine could justify an evening ticket (from 17:00, 3,500 yen), but dates and hours are not yet published.
The GREEN×EXPO Association will sell 2,027 RING PASS season passes made from Expo 2025 Grand Ring timber at 50,000 yen. Lottery entries 18 to 30 September 2026.
Our take: Of the 50,000 yen, 28,000 is the regular season pass and 22,000 is the wooden ticket and postage; pass holders pay only the difference. It is the third use of Grand Ring timber in Yokohama after KAJIMA TREE and the Kanagawa pavilion's flower bed, and the first sign that the city holds some of the wood.
On 15 September 2026 Yokohama seed company Sakata Seed detailed its five GREEN×EXPO 2027 exhibits: a garden of 160 varieties, a seed pavilion and two indoor shows.
Our take: A seed company founded in Yokohama brings five exhibits to its home Expo: a garden, a pavilion, indoor shows in May and July, and a second garden by its landscaping arm. The garden's 160 or so varieties are enough to walk around reading name tags. Locations and reservations are not stated.
On 15 September 2026 Sumitomo Forestry revealed the route through its GREEN×EXPO 2027 pavilion Hyaku no Mori: a tunnel, a theatre, a museum and a rooftop deck.
Our take: A forestry company opening its pavilion with the apparent contradiction of protecting forests and felling trees is putting its own business on display. The answer is given inside, so this is a pavilion to walk in order. Time needed, reservations and the location in the venue are not stated.
On 14 September 2026 the GREEN×EXPO Association named travel agency JTB a Platinum Partner. Promotion in 255 branches; tickets and hotels on JTB's Expo site.
Our take: After the Osada advertising group and Keikyu, JTB is the third Platinum Partner of the awareness-building project we know of, and the first travel agency. Its Expo site bundles official tickets with hotels in Yokohama, Shin-Yokohama and Kawasaki. Whether branches will sell tickets over the counter is not stated.
Kanagawa Prefecture has paired its mascot Kanagawa Kintaro with GREEN×EXPO 2027's Tunku Tunku on pin badges and key rings, on sale in two Yokohama department stores since 15 September 2026.
Our take: The prefecture's own mascot alongside the Expo's, on pin badges at 715 yen and key rings at 825 yen. Both stores are next to Yokohama Station. How many designs there are, and how long they stay on sale, has not been announced.
Japan will issue a 1,000-yen silver coin for GREEN×EXPO 2027 showing Tunku Tunku and six native plants: 40,000 coins at 33,500 yen, applications from 2 December.
Our take: This is a keepsake: 33,500 yen for a coin with a face value of 1,000 yen. Shipping starts in late March 2027, after opening day, so it will not be in your pocket on 19 March. Applications run for about three weeks from 2 December, and the release does not say what happens if demand exceeds the 40,000 coins.
Kanagawa Prefecture will give local groups flower seedlings, normally 50 each, and GREEN×EXPO 2027 signs. Applications run 6–16 October 2026.
Our take: Travellers will not be applying, but from late November GREEN×EXPO 2027 signs will start appearing beside flowers in parks and nursery gardens across the prefecture. If you spot one near a station, it comes from this programme.
Kanagawa Prefecture will run a GREEN×EXPO 2027 booth at the 51st Fujisawa Citizens' Festival on Sunday 27 September only, at Sunpearl Plaza by Fujisawa Station.
Our take: Kanagawa's booth is at the plaza just outside Fujisawa Station's north exit on Sunday 27 September only. What the booth will offer has not been announced, so treat it as a detour on a day out to the Shonan coast.
The GREEN×EXPO Association and Triathlon Japan have a partnership running to the end of 2027, with Expo booths at race venues and athletes posting on social media.
Our take: The Yokohama race is held every May, so the 2027 edition falls in the middle of the Expo. Watching the race and then heading to the venue could make a day out, but what will happen at the race has not been announced.
On 10 September 2026 the GREEN×EXPO Association added Colombia, Nauru and Libya to its participant list, for 74 countries and 5 international organisations.
Our take: With the Association saying it has reached its target of around 70, the invitation phase looks nearly done. What comes next is each country's exhibit: 55 countries have signed official participation contracts, and about seven of them have shown their direction (corrected 18 September 2026).
On 8 September 2026 Kanagawa gave a first look at its GREEN×EXPO 2027 pavilion: the logo, the mascots VIBRANTs and Momon, a theatre film and staff uniforms.
Our take: The Kanagawa Pavilion reuses Grand Ring timber from Expo 2025 in its flowerbed and changes with the season, from canola at the opening to sunflowers in July. Its two mascots are the prefecture's own, with no English names or merchandise announced yet.
On 8 September 2026 the GREEN×EXPO Association named Keikyu, the railway serving Haneda Airport, a Platinum Partner under its project sponsorship programme.
Our take: Keikyu, the railway between Haneda Airport and Yokohama, has joined the 500-million-yen-plus sponsorship tier. Visitors from abroad will now see Expo posters on the first train they board. Keikyu does not serve the four shuttle-bus stations, so the change at Yokohama Station stays the same.
Kanagawa runs a GREEN×EXPO 2027 booth at Vietnam Festa in Kanagawa 2026 (12–13 September, Yokohama), with origami and Tunku Tunku appearing on the 13th.
Our take: Tunku Tunku appears three times on Sunday 13 September, and every time is approximate. The venue is a one-minute walk from Nihon-Odori Station and free to enter, so it fits into a day of sightseeing in Yokohama.
Goods pairing Tunku Tunku with Garden Bear, Yokohama's flowers-and-greenery character, sold at a pop-up in the Autumn Satoyama Garden Festa 2026 (5–27 September).
Our take: Satoyama Garden was a venue of the 2017 national greening fair in Yokohama, and buses reach it from Mitsukyo, one of the Expo's shuttle-bus stations. Buy the goods, then walk the autumn flower bed to get a sense of scale for next spring.
On 3 September 2026 the GREEN×EXPO Association announced that a Shinkansen train wrapped in GREEN×EXPO 2027 livery will start running to mark six months before opening.
Our take: The wrapped trains run on JR East's Tohoku-Hokkaido and Joetsu-Hokuriku Shinkansen lines, not the Tokaido Shinkansen. They never come to Yokohama, so this is a way for people travelling to Tokyo from eastern Japan to see the Expo on board or at Tokyo Station.
From 18 September 2026, admission tickets with timed entry will be sold at 7-Eleven, FamilyMart and Lawson stores across Japan.
Our take: A paper ticket that already carries your entry slot means a family can buy everything at a shop counter. Changing the slot still needs the ticket ID registered online, so if your dates may move, the official site is the easier route.
Tokyo Skytree will be lit in Tunku Tunku's four colours on 15 September 2026, 9 December (100 days to go) and opening day, 19 March 2027.
Our take: On 15 September the lighting runs from 19:00 to midnight. Through trains on the Tokyu Den-en-toshi Line run from Minami-Machida Grandberry Park, an Expo shuttle-bus station, to Oshiage (Skytree-mae) without a change, so the Expo and the Skytree sit on one line.
Official Moomin and Tunku Tunku goods: a mug (¥2,970) and plate (¥2,860) around January 2027, then handkerchiefs and an eco bag around late February to early March.
Our take: Releases fall between January and early March 2027, just before opening: the mug and plate first, the handkerchiefs and eco bag later. Sales outlets are not announced, so we do not know whether the Yamashita Park pop-up store will carry them.
Official pop-up stores open from September 2026 in Yamashita Park, Yokohama (to 31 May 2027), plus short runs at Kintetsu Wakayama and Kintetsu Yokkaichi.
Our take: The Yamashita Park store stays open until 31 May 2027, so you can buy official goods while sightseeing in Yokohama even on a day you do not go to the venue. It is far from the venue in Seya-ku and Asahi-ku, so treat it as a stop for a different day. On 18 September the Association announced that the pop-up stores would spread to 157 Cainz stores nationwide.
On 31 August 2026 the organiser named the Osada advertising group a Platinum Partner. Its 230-plus digital signs will carry Expo content for up to 13 months.
Our take: Platinum is the 500-million-yen-plus tier, and an outdoor advertising group has joined the awareness-building project. Up to 13 months from September means Tunku Tunku on street screens right through to the closing.
On 31 August 2026 the GREEN×EXPO Association announced a transport demand management trial to reduce traffic congestion linked to the Yokohama Expo.
Our take: The trial targets Yokohama and Shin-Yokohama stations from 8:00 to 10:00 and 16:00 to 18:00. That tells us the organiser expects Expo traffic to overlap with the commuter peaks at these two transfer stations. No date is given for publishing the results.
On 27 August 2026 the organiser set out timed entry: reservations open 18 September, changeable up to three times, and same-day booking for some exhibits.
Our take: You can change your entry slot up to three times, and the outdoor gardens need no reservation at all, so planning is far easier. Some exhibits use same-day reservations only, one per ticket per day.
Five licensed Mizuno products pairing Myaku-Myaku and Tunku Tunku, including ¥17,600 shoes and a ¥6,490 T-shirt. Pre-orders from 22 August 2026.
Our take: This is billed as the first round of goods carrying both the Osaka 2025 and Yokohama 2027 characters. General sale comes in March 2027, right before opening, so we expect many people to wear these on day one. The Osaka store on the pre-order list is there to bring Expo 2025 visitors on to Yokohama.
Japan's Ministry of Foreign Affairs updated its GREEN×EXPO 2027 participant list on 5 August 2026: 71 countries and regions and 5 international organisations.
Our take: As of 4 August, 71 countries and regions and 5 international organisations. The large African contingent lines up with TICAD 9, held in Yokohama in August 2025. The count rose to 74 on 10 September.
Myaku-Myaku and Tunku Tunku goods that sold out in 2025 return with six new items and four restocks, on sale from 18 March 2026 (20 March at Maruzen Marunouchi).
Our take: A restock five months after the Osaka Expo closed, with a clear aim of carrying its popularity over to Yokohama. The four restocked items cost 520 to 770 yen, an easy souvenir before opening day. The Maruzen Marunouchi store is right outside Tokyo Station, handy on a Shinkansen transfer.
