The NTT EAST Pavilion's flowerbed will be planted by Yokohama pupils and local nursery children

• NTT East and its group company Biostock announced on 15 October 2026 that the flowerbed at the NTT EAST Pavilion at GREEN×EXPO 2027 will be built from flowers grown by schools, local groups, companies and NTT East staff, brought to the site in turn.
• Pupils at Yokohama Municipal Minami High School Junior High School will grow flowers in compost made partly from school-lunch leftovers, and design the flowerbed themselves. The flowers are due to be shown on the Expo site; a first class was held on 8 October.
• The pots are “closure pots”, made with the firm Koreyakono from used fibre-optic closures, the casings that protect cable joints.
• Children at Azumano Kindergarten and Azumano Nursery, run by the Kamata Gakuen school corporation near the site, will also grow flowers in these pots. Once moved into the pavilion’s bed, they will be looked after by pavilion staff.
• Liquid fertiliser from NTT East’s own food waste, made in a small biogas plant, is due to be used on the bed.
• When the flowers go in, how many times, and whether members of the public can take part are not stated.
• The English names of the schools and companies are trip-jp’s own renderings.

Our take

Until now, what was known about the NTT EAST Pavilion came mostly from the April groundbreaking: its concept is “Well”, and it plans hands-on experiences using technology such as IOWN (see our pavilion overview). The way the flowerbed will be made has been settled before the exhibits themselves.

The flowers will be brought in one batch after another, so this is not a bed planted once and left until closing. The number of changes and whose flowers arrive in which month are not given, but a visitor at the March opening and one in September should see different beds.

The people growing the flowers are named, too: pupils at one Yokohama school and children at one nursery near the site. That gives local families a reason to visit once the Expo opens.

Tips for visitors

• The Expo runs from 19 March to 26 September 2027. The pavilion’s location and entry arrangements are not yet out; our pavilion overview lists it alongside the other corporate pavilions.
• NTT East plans to share the process of growing the flowers and bringing them to the site. Where it will post updates is not stated, but its special site covers the pavilion.
• There is no railway station at the site. Shuttle buses run from Seya, Mitsukyo, Minami-machida Grandberry Park and Tokaichiba; see our shuttle bus guide.
