The facade and equipment of Panasonic Group’s Expo 2025 pavilion “Nomo no Kuni” will be used again at the GREEN×EXPO 2027 venue, in “Yasashiku Naritai. STUDIO.” Toho Leo is developing the building as one of the Village pavilions, and its theme is “eight-year-old adults.”
According to Toho Leo’s dedicated site, the grand opening is planned for 19 March 2027. Toho Leo is building it in the “Urban GX Village” area of the Village exhibits.
The theme: “eight-year-old adults”
The GREEN×EXPO Association, which runs the venue, lists “Yasashiku Naritai. STUDIO” as one of its 12 Village pavilions. Its formal name is the 2027 Japan International Horticultural Expo Association. The association’s page says the building reuses “Nomo no Kuni” and gives the theme as “eight-year-old adults,” alongside the line “we want everyone, adults and children alike, to become kinder.”
Reusing Panasonic’s “Nomo no Kuni”
Toho Leo and Panasonic Holdings each issued announcements on 29 July 2025. Both said that Nomo no Kuni’s facade (roughly 736 steel-frame pieces), 40 lights, 12 speakers and mist equipment would be reused in the STUDIO (then called “STUDIO, tentative name”) that Toho Leo is building within Urban GX Village. The facade was designed by architect Yuko Nagayama.
On 4 September 2025, Panasonic Group announced that, following Nomo no Kuni’s closure, it would reuse or recycle over 99% by weight of building materials such as recycled steel, copper, the facade frames and exterior paving blocks. In its announcement of 22 December 2025, it said this had been achieved.
On 22 December 2025, Panasonic Group also announced the destinations it had chosen for the pavilion’s exhibits, which more than 470,000 visitors had experienced: airports, local governments, schools and other facilities. That was a separate effort from the facade reuse, and the STUDIO is not among the destinations listed in that announcement.
Architectural concept
According to Toho Leo’s dedicated site, the STUDIO’s concept is “softness over strength, sharing over ownership, growing over completion.” The site describes a woven structure of flexible line materials with climbing plants trained over it, so that its appearance changes over time as the foliage fills in.
The STUDIO shares its philosophy with “Yasashiku Naritai,” a project by the magazine AERA (Asahi Shimbun Publications) and producer Kaido Koyama. Koyama is the project’s special organiser. Specific exhibits or activities planned inside the building have not been announced as of September 2026.
University partnerships
On 25 May 2026, Toho Leo announced that it was launching a “regional co-creation programme” with Japan GX Group and the Hosome Cross-University Laboratory. The programme is based at the STUDIO and aims to connect local natural capital to policy, business and citizen participation.
Kyoto Sangyo University announced on 19 June 2026 that it would collaborate with Toho Leo’s Village pavilion “Yasashiku Naritai. STUDIO.” The exhibit is led by its Faculty of Life Sciences (whose Department of Industrial Life Sciences is to be renamed the Department of Environmental Life Sciences in April 2027) together with several other faculties. Its theme is dialogue with nature. A special exhibit inside the STUDIO is planned for 7 to 20 August 2027, and a separate indoor exhibition booth on flowers and greenery for 7 to 15 August 2027. Students are also set to take part in preparing and running the exhibits.

Because Panasonic announced the building’s reuse and the exhibits’ relocation separately, it is clear that only the exterior and equipment are going to the STUDIO. Since May 2026, two announcements have concerned partnerships with universities and companies.
