GREEN×EXPO 2027 in Yokohama: dates, tickets, and what to know before you plan
If you are planning a Japan trip for spring or summer 2027, GREEN×EXPO 2027 is likely to shape hotel prices and day-trip plans around Yokohama. It is a large international horticultural exposition, and the useful details, dates, ticket tiers and the location, are already public. A few things that matter most for visitors, such as reservations and bus timetables, are not. This guide separates the two.
GREEN×EXPO 2027 runs March 19 to September 26, 2027 in Yokohama. Adult one-day tickets are ¥4,900 in advance (on sale until Mar 18, 2027) and ¥5,500 from opening day; a night ticket (entry after 5 pm) is ¥3,500. The site is a former communications facility in Asahi and Seya wards, not at Yokohama Station or the waterfront, so plan buses and allow a long return buffer. Visit-date reservations have not been detailed yet.
I do not know yet what GREEN×EXPO's grounds will look like, so I cannot show you. This is the Osaka Expo, where I took the frame above, and it is what I think of when I imagine a large outdoor expo: long walks, grass, and a lot of people lying down to rest in the shade. Bring that mindset, and plan your rest stops.

Getting there: the part to plan carefully
The site is about 100 hectares in northwestern Yokohama, away from the city's main sightseeing areas. The access options listed so far are shuttle buses, direct buses, group buses, park-and-ride, car, bicycle and walking; the car parks on the north and west sides need advance booking. I could not find a specific train route and timetable confirmed yet, so I will not guess one. Until the organisers publish bus routes, fares and last-return times, treat the journey from central Tokyo as a half-day commitment each way once you include transfers, and do not book a flight, Shinkansen or airport transfer for the evening of your visit.
Because the site is large and outdoors, the season you pick matters more than the ticket tier. July and August are hot, which is what the night ticket and summer pass are for. Spring and September are the comfortable months. Bring water, sun protection and shoes you can walk in, and save your ticket QR code offline in case the signal is weak.
Which ticket should you buy?
If your dates are fixed, the ¥4,900 advance ticket saves ¥600 against the regular price, and it is the only one currently on sale. If you are visiting in July or August and would rather come in the cooler evening, the ¥3,500 night ticket is worth considering, but it only starts on opening day and you will need to check closing times. The season pass makes sense only for people living in the Kanto area. One caution: the organisers say visit-date and time reservations will be introduced later, so do not assume a ticket alone guarantees entry on a given day until the rules are published.
What is still unconfirmed
As of October 2026 I could not confirm opening hours, closed days, bus timetables, the reservation process, or the full programme of seasonal displays. These are the details most likely to change your plan, so check back closer to March. If you are building a spring 2027 itinerary, pair it with the cherry blossom season, and keep an extra day free around the expo in case of weather.
