GREEN×EXPO 2027 Highlights and Pavilions to Watch: The Five Villages and Must-See Halls
The grounds cover about 100 hectares, and the expo runs for 192 days. GREEN×EXPO 2027 (the 2027 International Horticultural Exposition) is built around flowers and greenery — it is not the kind of event with roller coasters and thrill rides. That is exactly why deciding in advance which halls to see, and with what interest, makes such a difference. This article walks through the pavilions confirmed so far and how to enjoy the five villages, sticking to what we can actually verify.
A quick note: this site is an unofficial guide. Always confirm the latest details on the official website. We also keep a running list on the pavilion guide page.
Start with the must-see halls (Japan Government Garden and Theme Pavilion)
If you’re not sure where to begin, these two are a safe bet.
The first is the Japan Government Garden. At roughly 2.5 hectares of exhibition space, it is among the largest on the grounds, and its theme is “The Japanese View of Nature.” It is set to feature an immersive theater-style exhibition, offering a chance to feel — rather than just read about — how people in Japan have related to nature for centuries. Because it’s large and likely to be popular, visiting in the morning right after the gates open will make the rest of your day easier. See the Japan Government Garden page for more.
The second is the Theme Pavilion, the conceptual backbone of the whole expo. It conveys the ideas of Nature-based Solutions (NbS) and the circular economy through art and hands-on experiences. That may sound abstract, but the core idea is simple: borrow nature’s own power to solve society’s problems. Seeing this first gives you a clear lens for everything else — the corporate halls and the villages alike. The Horticultural Culture Pavilion is another of the major facilities, and a good fit if you want to dive deeper into horticulture itself.
Build your day around two or three of these anchor halls, and even a 100-hectare site starts to feel manageable.
Standout halls in Urban GX Village (Obayashi, Mitsubishi, Kajima, Daiwa House and more)
If technology and city-building appeal to you, Urban GX Village is the place to head. Themed around “cutting-edge technology for a green society,” it brings together some of Japan’s best-known companies. The exhibitors confirmed so far are:
- Morisora Mirai (Obayashi) — a major construction firm’s hall on the future of cities and forests
- Minna no Mirai-kan (Mitsubishi) — the Mitsubishi group’s vision of future living
- Kajima Tree (Kajima) — Kajima Corporation’s hall built around the idea of a “tree”
- Endless Heart Park (Daiwa House) — a park-style exhibition by Daiwa House Industry
- Yasashiku Naritai. STUDIO (Toho Leo) — a hall reusing the facade of Panasonic’s “Nomo no Kuni” pavilion from Expo 2025 Osaka, Kansai
- NTT East Hall — an exhibition and event space by NTT East
- Mobitas (KT Group) — the KT Group’s hall on the theme of mobility
- Tokyu Group (hall name not yet announced)
Toho Leo’s reuse of building materials from Expo 2025 Osaka is a nice example of the circular-economy spirit at the heart of this expo. A practical plan is to take in the technology halls together in the morning, then move on to the other villages in the afternoon.
Note that the Tokyu Group hall has not yet been named, and the specific contents of each hall are expected to be announced later. We’ll update this site as more information is released.
Standout halls in Farm & Food Village (JA, Meiji, Yamazaki Baking, Sakata Seed)
If you’re drawn to food and wellbeing, head to Farm & Food Village. Themed around agriculture, food and healthy living, it’s a smart area to tour around lunchtime. The confirmed exhibitors are:
- JA Pavilion — a hall on farming and food by JA (the agricultural cooperatives)
- Meiji “ORAGA VILLAGE” — the major food company Meiji’s vision of a future hometown
- Yamazaki Baking “A Brighter Table Tomorrow” — a hall on the dining table by Yamazaki Baking
- Sakata Seed “A Traveling Seed and Me” — an exhibition by the major seed company Sakata Seed, with a seed as its traveling protagonist
The one with a perspective only a seed company could offer is Sakata Seed’s “A Traveling Seed and Me.” The story of a single seed journeying across the world resonates naturally with the theme of a flower-and-greenery expo. See the Sakata Seed page for details. Because this is where the food-related halls cluster, you can tour them while keeping yourself fed — a practical perk of this village.
The five villages at a glance and how to enjoy them
The grounds are organized into five “villages.” Knowing the character of each makes it easier to pick the areas that match your interests.
| Village | Theme | Best for |
|---|---|---|
| Urban GX Village | Cutting-edge technology for a green society | Fans of technology, architecture and city-building |
| Craft Village | Traditional crafts living in harmony with nature | Anyone drawn to crafts and making things |
| Farm & Food Village | Agriculture, food and wellbeing | Those interested in food and healthy living |
| Kids Village | Hands-on nature education for the next generation | Families with children |
| SATOYAMA Village | The comfort of people and nature coexisting | Lovers of countryside scenery and nature walks |
Of these, the exhibitors for Craft, Kids and SATOYAMA villages have not yet been announced. Even so, their themes are clear, so you can sketch out the big picture now — families might center their day on Kids Village, while anyone who’d rather stroll through nature could build around SATOYAMA Village.
The trick to enjoying it all is to favor the villages you care about rather than spreading yourself thin across all five. Lean into Urban GX if you love technology, or make Farm & Food your base if food is the draw — that turns your route into a single connected line and saves your legs. Choosing your day of the week helps too: in the official daily visitor estimates, weekdays (outside Golden Week and the summer holidays) draw about 50,000 people a day, versus roughly 105,000 on peak-period weekends and holidays — more than double. If you can aim for a Tuesday, Wednesday or Thursday, the grounds will simply feel easier to walk. For detailed timing and itineraries by who you’re with, see our model courses article.
Seasonal flowers are a highlight in their own right. As a general guide for Yokohama and the wider Kanto region, tulips peak in late March to April, nemophila in April, wisteria in late April to early May, roses from mid-May to June, hydrangeas in June, sunflowers in late July to August, dahlias from late August to September, and cosmos in September. The specific plantings on the grounds await official announcement, but making the flowers in season one of your goals adds a pleasure quite different from hall-hopping. See our bloom calendar for more.
More highlights to come with future announcements (national pavilions and more)
Everything above is what we can confirm at this point. GREEN×EXPO 2027 has 70 countries and regions signed up to take part, but details of their individual pavilions have not yet been released. As the overseas halls come to light one by one, the list of highlights will keep growing.
Likewise, the exhibitors for the Craft, Kids and SATOYAMA villages, the name of the Tokyu Group hall, and the specific contents of each corporate hall are all expected to be announced in stages. Where information isn’t confirmed — such as the involvement of particular architects — this site won’t state it as fact, and we’ll update as announcements are made.
For reference, although the scale, venue and theme are different, Expo 2025 Osaka, Kansai saw information about participating countries’ pavilions come together gradually as the opening approached. Yokohama will likely follow a similar path, with the full picture emerging little by little ahead of opening day. The right stance is to anchor your plan with the confirmed must-see halls for now, while looking forward to each new announcement.
Once you have a sense of the highlights, the next step is the practical planning. See the pavilion guide for the full list of halls, the model courses for itineraries by time and company, and What is GREEN×EXPO 2027? for an overview of the expo itself.
