GREEN×EXPO 2027 Pavilions — Are Reservations Required? (Latest Info)
“Do I need to reserve a slot to get into the popular pavilions at GREEN×EXPO 2027?” If you watched the scramble for pavilion reservations at the Osaka–Kansai Expo, this is probably top of mind. So, the honest answer up front: as of mid-2026, no per-pavilion reservation system has been announced for the 2027 horticultural expo in Yokohama. That said, a mechanism to manage how busy the venue gets on any given day is already taking shape. This article separates what is officially confirmed from what we’re still waiting on. (This is an unofficial guide — always confirm the final details on the official site.)
Are there individual pavilion reservations? (Not yet — expected later)
Let’s start with the question everyone asks. As of June 2026, there is no announced system for reserving a specific pavilion at a set time. The Osaka–Kansai Expo used advance lotteries and same-day bookings for its most popular pavilions, but whether Yokohama will adopt the same approach simply hasn’t been decided.
It helps to keep the difference in character in mind. A horticultural expo is about flowers and greenery — it isn’t built around large thrill rides. The stars here are outdoor gardens and plantings, international exhibits, the Theme Pavilion and theater-style shows. That means crowds may not pile up in one spot the way they did at Osaka. Even so, a venue with an immersive theater could meter entry in timed groups.
A practical way to plan around this:
- Treat individual reservations as “to be announced.” Don’t lock in a schedule that assumes they exist.
- Use Osaka’s reservation flow only as a loose reference — not as confirmed Yokohama detail.
- What you can count on are the timed-entry plan below, plus advance booking for shuttle buses and parking.
Timed entry and how it relates to pavilion crowds
Even without per-pavilion booking, a system to manage the date and time of your visit is planned. Here’s how the pieces fit.
Tickets aren’t date-specific yet — but “timed entry” is coming
Right now, official tickets are not tied to a specific date. Advance sales begin on March 19, 2026. Early-bird tickets (through March 18, 2027) are ¥4,900 for adults; same-day tickets during the expo are ¥5,500; a season pass is ¥28,000. Children aged 3 and under are free. On top of this, a timed-entry reservation system is expected to launch to spread out crowds, though the exact steps and start date are still unconfirmed. In other words, buying a ticket may not be the same as securing your visit slot. (Check the official tickets page for the latest.)
When you go changes everything
The official daily attendance forecast shows that picking the right day directly shapes how comfortable your visit will be.
| Category | Expected visitors | Approx. days |
|---|---|---|
| Weekdays (before Golden Week / summer break) | ~50,000/day | 80 days |
| Weekdays (after Golden Week / summer break) | ~56,000/day | 47 days |
| Weekends & holidays (off-peak) | ~79,000/day | 46 days |
| Peak (Golden Week, September weekends, etc.) | ~105,000/day | 19 days |
Peak days draw more than double the crowds of a quiet weekday. If you want to take your time at the headline pavilions, build your plan around a weekday — ideally Tuesday to Thursday — and aim for right after opening or late afternoon. The rainy season and the height of summer tend to be relatively quiet (a general rule of thumb). Combined with advance transport booking, “go on a quiet day” is your best move for the popular pavilions.
Don’t forget to book your trip to the venue
There is no station next to the venue. The standard route is a reservation-only shuttle bus from one of four stations: Seya, Mitsukyo, Tokaichiba, or Minami-machida Grandberry Park. Service scales from about 90 buses a day on weekdays to roughly 160 on peak days, and shuttles from Yokohama and Shin-Yokohama stations are under consideration to ease congestion. Driving is also reservation-based — on-site parking (about 5,900 spaces on the north side plus around 600 on the west, among others) requires advance booking, and park-and-ride at locations such as AEON Mall Yamato is arranged for peak periods. See our access guide for the full picture. Getting to the popular pavilions early starts with getting to the venue early — and that begins with a transport reservation.
The headline pavilions: Japan Government Garden and the Theme Pavilion
Here’s what we can say about the likely crowd-pullers, based on confirmed information.
The Japan Government Garden is one of the largest at the expo, with an exhibition area of about 2.5 hectares. Its theme is “Japan’s View of Nature — Learn, See, Live,” and it is described as an experiential facility featuring an immersive theater. By sheer scale alone, it is shaping up to be a highlight of any visit. We’ll keep details current on the Japan Government Garden page.
The Theme Pavilion is the core facility carrying the expo’s overall message. It conveys Nature-based Solutions (NbS) and the circular economy through exhibits and hands-on experiences. If you want to grasp the spirit of the expo first, this is a clear place to start. See the Theme Pavilion page.
The Horticulture Culture Pavilion is another main facility. A total of 70 countries and regions are taking part, but details of individual national pavilions have not yet been announced. We’ll add the international highlights as soon as they’re released.
Pavilions confirmed so far
The grounds are organized into five villages. Below are the pavilions that have been confirmed (names and exhibitors may still change).
Urban GX Village (cutting-edge technology)
- Morisora Mirai (Obayashi) / Minna no Mirai-kan (Mitsubishi) / Kajima Tree (Kajima)
- Endless Heart Park (Daiwa House) / “Yasashiku Naritai.” STUDIO (Toho Leo)
- NTT East Hall / Mobitus (KT Group) / Tokyu Group (name TBA)
Toho Leo’s “Yasashiku Naritai.” STUDIO stands out for reusing the facade of Panasonic’s “Nomo no Kuni” pavilion from the Osaka–Kansai Expo — a fittingly sustainable touch for a horticultural expo.
Farm & Food Village (agriculture, food and wellbeing)
- JA Pavilion / Meiji “ORAGA VILLAGE: Hometown of the Future”
- Yamazaki Baking “A Bright Table for Tomorrow” / Sakata Seed “Traveling Seeds and Me”
Note that exhibitors for the Craft, Kids and SATOYAMA villages have not yet been announced. We’ll add them to the pavilion list as soon as they’re confirmed.
What to watch for once announcements land
Finally, here are the items still awaiting an official word. We’ll update this article and the related pages as each one is released.
- The start date and exact steps for timed-entry reservations (and how they link to tickets)
- Whether individual pavilion reservations will exist (advance booking, same-day numbered tickets, etc.)
- Details of the national and regional pavilions (what the 70 countries and regions will show)
- Exhibitors for the Craft, Kids and SATOYAMA villages

For now, the takeaway is simple: rather than fretting over pavilion reservations, your surest preparation for a comfortable visit to the popular pavilions is to pick a quiet weekday and lock in your transport in advance.
