GREEN×EXPO 2027 Access Guide: Getting to Kamiseya, the 4-Station Shuttle and Parking (Reservation Only)
GREEN×EXPO 2027 takes place on the former Kamiseya Communications Facility site, a roughly 100-hectare stretch of land straddling Asahi and Seya wards in Yokohama. The first thing most visitors run into is a simple question: how do you actually get there? The short answer is that there is no station right next to the grounds — so planning your route in advance makes the day far smoother.
This guide pulls together the train-plus-shuttle, car, and airport options in practical terms, based on the official visitor transport plan (2nd edition, February 2026).
Why there is no station at the gate, and the smart way in
The Kamiseya site is a large former US military communications base, and no railway runs across it. There is no station that delivers you straight to the grounds, and even the nearest rail stations are not within walking distance — that is the starting point for everything below.
The organizers’ answer is a reservation-only shuttle bus linking four nearby stations to the venue. For most visitors, the basic route is “train to the nearest station, then shuttle from there.”
If you are not sure where to start, here is the bottom line.
- By public transport — take a train to Seya or Mitsukyo (Sotetsu Line), Tokaichiba (JR Yokohama Line), or Minami-machida Grandberry Park (Tokyu Den-en-toshi Line), then transfer to the shuttle.
- By car — both the venue car parks and the shuttle are reservation only. You cannot simply turn up on the day and expect to park or board.
- To avoid crowds — weekdays, especially Tuesday to Thursday, tend to be calmer. For a detailed outlook, see the crowd forecast.
Train plus the 4-station shuttle (Seya, Mitsukyo, Tokaichiba, Minami-machida Grandberry Park — reservation only)
The shuttle runs from these four stations.
| Station | Line | Position relative to the venue |
|---|---|---|
| Seya | Sotetsu Main Line | Close to the southern side |
| Mitsukyo | Sotetsu Main Line | Next stop to Seya; also from the south |
| Tokaichiba | JR Yokohama Line | From the northeast |
| Minami-machida Grandberry Park | Tokyu Den-en-toshi Line | From the west; a shopping complex makes the wait easy |
In practice, choose your station by the transfers and travel time from home. From central Yokohama, Shinjuku or Shibuya, the Sotetsu or Den-en-toshi lines work well; from the Machida or Hachioji direction, the JR Yokohama Line is the natural choice.
According to the official plan, service scales up to roughly 90 buses a day on weekdays and around 160 a day at peak times. To spread the load, routes starting from Yokohama Station and Shin-Yokohama Station are also under consideration — the idea being to add entry points so that visitors do not all funnel into the same four stations.
One thing to keep in mind: the shuttle is reservation based. It is designed around booking a seat in advance. The exact booking method and when reservations open have not yet been announced, so check the official access page for the latest steps before you set out.
Private cars, the venue car parks (about 5,900 spaces north + 600 west, reservation only), motorcycles and bicycle parking
If you would rather drive, the venue has car parks too. Here is the scale.
- North car park — about 5,900 spaces
- West car park — about 600 spaces
- Motorcycles — about 1,000 spaces
- Accessible parking — about 200 spaces
- Group buses — 430 spaces north + 250 west
That is roughly 6,500 car spaces in total, which sounds generous — but again, advance reservation is the key. The venue car parks are for booked vehicles only; they are not set up for hunting down a free spot on the day. When and how to reserve will be announced later.
For anyone living within cycling distance, there is also bicycle parking for about 1,700 bikes. If you are coming from nearby, a bicycle sidesteps both traffic and reservations, which makes it a surprisingly strong option.
Park-and-ride at peak times (Aeon Mall Yamato, Sagami-ono and more) and partner car parks
During peak periods — Golden Week, the summer holidays, the September long weekends — the venue car parks alone are expected to fill up. To handle this, the organizers plan park-and-ride: leave your car a little away from the grounds and continue to the venue by shuttle or bus.
The official plan names sites such as:
- Aeon Mall Yamato / Ito-Yokado Yamatotsuruma — about 500 spaces combined
- Sagami-ono — about 200 spaces
On top of these, nearby partner car parks are expected to be used as well. If you are driving during a busy stretch, it helps to keep both options in mind — the on-site car park and the “park further out and transfer” approach — so the day goes smoothly. Details on reservations and operations at each site will be announced later.
Routes from Haneda, Narita and other directions
Coming from far away, or from abroad, the logic is the same: head into central Yokohama first, then make for one of the four stations.
- From Haneda Airport — travel toward Yokohama, then take the Sotetsu, JR Yokohama or Tokyu Den-en-toshi line to one of the four stations. If routes from Yokohama or Shin-Yokohama are set up, those become options too.
- From Narita Airport — head toward Yokohama or Tokyo first, then aim for the four stations just as you would from Haneda.
There is no service that runs directly to Kamiseya from the airports; think of it as passing through Yokohama, a large hub, on the way. As the opening approaches, information on airport limousines or extra services may appear, so check it alongside the latest transport details.
When do reservations open? (Date-and-time booking to be announced)
You will have noticed the phrase “reservation only” several times above. Both the shuttle and the venue car parks assume advance booking — yet at this point, the opening date and the exact steps for reservations have not been published.
Tickets themselves go on advance sale from March 19, 2026 (for now, tickets are not tied to a specific date). Separately, a date-and-time visit reservation system is expected to start, but its procedure is not finalized either. At Expo 2025 Osaka, Kansai, date-and-time booking became a central crowd-management tool; Yokohama may not work exactly the same way, so we will not state it as fact here.
This is the part that tends to update quickly once it gets moving. Ticket types and prices are collected on the tickets page, and the latest transport and reservation steps will go on the official access page. As one last step before the day, always check the most recent version.
