- The light-up runs from Monday 23 November 2026 (a public holiday) to Monday 11 January 2027 (a public holiday). It is free and needs no booking.
- At the north exit the lights are on from 17:00 to 22:00. Fourteen trees along the avenue and one at the north-east corner of the plaza are lit in changing colours, and Tunku Tunku, the Expo’s official mascot, is projected on the station wall. Seya Ward Office is the organiser, with two supermarkets by the station as co-hosts.
- At the south exit the bus rotary has illuminations from 18:00 to 20:00, powered by solar panels and storage batteries, with a sign promoting the Expo. Because it relies on solar power, it may not light up on some days.
- On the first day, 23 November, a lighting event starts at about 16:50 in the north exit plaza, with a countdown and a performance by a local gospel choir. It is cancelled in case of rain.
Our take
Last year’s release for the same event described about 30,000 gold LED bulbs at the north exit. This year no bulb count is given, and the design has changed to lighting the trees themselves in shifting colours. The mascot projection on the station wall continues from last year.
The light-up ends on 11 January, a little over two months before the Expo opens on 19 March. The ward says it is holding it to build excitement from Seya Station, one of the stations nearest the venue. If you have a reason to get off at Seya before the opening, for example to look around the area near the site, timing your return for after 17:00 will take you past the north exit lights.
Keep in mind that the two exits keep different hours. The south side goes dark at 20:00 and may not light up at all after a run of cloudy or rainy days.
Tips for visitors
- The lighting event is at about 16:50 on Monday 23 November in the north exit plaza of Seya Station. It is cancelled if it rains.
- Seya is on the Sotetsu Main Line. Routes from Yokohama Station are in our access guide.
Our take
The two exits keep different hours: 17:00 to 22:00 at the north exit, 18:00 to 20:00 at the south. The south side runs on stored solar power, and the ward says it may stay dark on some days. If you go, see the north exit first.
