GREEN×EXPO 2027 Shuttle Bus & Parking Guide (Reservations Now Open)

At GREEN×EXPO 2027 (the 2027 International Horticultural Exposition in Yokohama), three reservation systems opened at once on Friday, September 18, 2026: timed-entry reservations for admission tickets, advance reservations for the four-station shuttle buses, and advance reservations for parking. All three are now being accepted on the official ticket site.

The date was announced in the organizers’ press release dated July 17, 2026.

This guide covers everything officially confirmed about the shuttles and parking — fares, fees, and how the system works — plus what to prepare before booking.

Three points of context first.

• September 18 is exactly six months before opening day (March 19, 2027), and the stated goal is to ease congestion on surrounding roads and spread out visitor demand
• The venue — the former Kamiseya Communications Facility site in Seya and Asahi wards, Yokohama — has no railway station of its own
• If you come by train, you take a shuttle bus from one of four stations; if you come by car, you use reservation-only parking. In other words, for almost every visitor, September 18 is the day you lock in how you’ll get there

Three reservations now open (since September 18, 2026)

First, the big picture. The officially announced schedule looks like this.

[September 20 update] All three reservation systems went live on September 18 as scheduled, following the ticket site maintenance on the evening of September 17. Reservations are now being accepted on the official ticket site.

[October 2 update] On September 20, the four-station shuttle bus reservation site sent a large number of duplicate “payment for your reserved bus is now open” emails to some users. The organizer says the bug was fixed at 13:49 the same day and that no personal data was leaked and no reservations or seats were affected (official apology, September 23, 2026). Receiving the same email several times does not mean you have duplicate bookings; check your booking on the reservation site if in doubt.

That said, some rules for timed-entry reservations are already fixed, per the August 27 press release.

• Reservations are first-come-first-served
• There are 7 time slots: 9:30 / 10:30 / 11:30 / 12:30 / 13:30 / 14:30 / 17:00 — you can enter at any time on or after your reserved slot
• Reservations cover the entire expo period
• You can change your reserved date and time up to three times. If you can’t make your reserved slot, you can move it to a later one
• Even after using all three changes, you can still enter on the day if same-day slots are available

Since September 18, convenience stores — Seven-Eleven, Lawson, and FamilyMart — also sell paper tickets with a date reservation built in, so no separate online reservation is needed for those tickets. (Source: September 2 press release.)

Shuttle bus basics: four stations, ¥200 for adults

The shuttle buses depart from four stations, listed here with their official line names from the press release:

• Seya Station (Sotetsu Main Line)
• Mitsukyo Station (Sotetsu Main Line)
• Minami-machida Grandberry Park Station (Tokyu Den-en-toshi Line)
• Tokaichiba Station (JR Yokohama Line)

The fares are officially published:

“Child” means aged 1 to under 12 (elementary school age or younger). Children under 1 ride free, and up to two children aged 1 to under 6 ride free per paying passenger. For families, that is a generous fare structure.

Journey times and service levels [August 2026 update]

The Visitor Transport Plan 3rd edition (July 2026) (full PDF) has revealed estimated journey times and service levels for each station for the first time.

The operating assumptions:

• Journey times are approximate and will vary with road conditions
• Shuttle service runs 8:30 AM to 10:30 PM (one hour before the 9:30 AM opening and one hour after the 9:30 PM closing)
• On regular weekdays about 90 buses per day are deployed; during peak periods (Golden Week, September weekends) that rises to about 160 buses per day

QR code at boarding and entry. You will need to display a QR code on your smartphone both when boarding the shuttle bus and when entering the venue. Turning your screen brightness to maximum and practising a pinch-to-zoom (two-finger zoom) gesture beforehand will help things go smoothly.

Advance reservations are now open as of September 18. For the latest operational details — whether every bus requires a reservation, whether same-day seats will exist — check the official website. We’ll update this article as news lands.

Cancellation policy [October 2026 update]

The cancellation terms for shuttle bus reservations are as follows (source: official access page, confirmed October 3, 2026).

• By 5:00 PM the day before: no cancellation fee (full refund of the fare)
• After 5:00 PM the day before through 5 minutes before assembly time: 50% cancellation fee (remainder refunded)
• 5 minutes before assembly time or later: cancellation not possible

If your plans might change, be sure to cancel before 5:00 PM the previous day.

On social media (X/Twitter), multiple users have reported that early time slots for shuttle buses on opening-period dates (late March to early April 2027) are filling up (as of October 2026). Return buses (venue to station) are also reportedly filling up, so booking both outbound and return trips together is recommended. If you have a preferred date, check availability on the official ticket site and book early.

Which station should you use?

The four stations sit on three different railway companies’ lines, so the basic rule is simple: pick the station on the line that involves the fewest transfers from where you live.

By starting point, the guide looks like this.

• Along the Sotetsu Line → Seya or Mitsukyo. They’re neighboring stations, so you can flexibly pick whichever has more open slots
• Southwest Tokyo (Shibuya, Setagaya) → the Tokyu Den-en-toshi Line to Minami-machida Grandberry Park is the natural route
• Long-distance visitors arriving by Shinkansen → transfer at Shin-Yokohama to the JR Yokohama Line for Tokaichiba

For a deeper station-by-station comparison, see our four-station shuttle comparison.

Reservations are now open, so the key is to think of your entry slot (one of 7 time windows) and your shuttle as a set. Securing an entry time is only half the job if no shuttle seat matches it. Slots are first-come-first-served, so act early for popular dates.

For picking less crowded dates (avoid Golden Week and September weekends), the crowd forecast guide is a good companion.

Parking fees and how it works: ¥5,000 weekdays, ¥7,000 weekends

If you drive, all venue parking is reservation-only. The officially published fees:

“Peak” is officially defined as weekends and holidays during Golden Week, September and similar periods. Venue parking consists of the North and West parking areas; motorcycle, accessible and priority spaces are in the North area only.

Parking capacity and approach routes [August 2026 update]

The 3rd edition transport plan also confirmed the parking capacity.

Approach routes assume the Tomei Expressway (Yokohama-Machida IC) and Route 16 Hodogaya Bypass (Kamikawai IC).

Park & Ride (peak days only, ¥3,000)

In addition, Park & Ride parking is offered on peak days only, at ¥3,000 per passenger car — you park farther out and ride a bus to the venue. The press release map places the lots at Sagami-ono (about 8 km from the venue) and Yamato (about 4 km).

On a peak weekend, that’s ¥4,000 cheaper than the ¥7,000 venue rate, which makes Park & Ride a serious money-saver if you must drive on a busy day.

General parking reservations are now open as of September 18, 2026. Group bus parking reservations opened earlier, on August 3, 2026.

Parking cancellation (passenger cars, group buses, and Park & Ride alike) is free of charge up to the day before your reserved date. Same-day cancellation is not possible, and no refunds are given (source: official access page, confirmed October 3, 2026).

Train or car: which is cheaper?

As a rough cost comparison between “shuttle round trip (¥400 per adult) plus train fare” and “¥5,000 weekday parking plus fuel”:

• One or two people → train plus shuttle is clearly cheaper
• A family of four or more driving directly from home → the ¥5,000 weekday parking rate starts to compete

What to prepare before booking (reservations now open)

Reservations opened on Friday, September 18, 2026 and are now being accepted. Here is what you need to have ready.

1. Secure your tickets first — Timed-entry reservations are made on the official ticket site and assume you already hold a ticket. Early-bird one-day tickets (¥4,900 for adults) remain on sale through March 18, 2027. The full price list is on our tickets page and in the ticket guide.
2. Have your 10-digit ticket ID ready — According to the official FAQ, even paper ticket holders need to register an account on the official ticket site and enter their 10-digit ticket ID on the registration screen to reserve. Keep the ID where you can find it.
3. Decide your dates and your station — Popular dates may fill quickly. Settle on second and third choice dates, and agree within your group on which station you’ll use (or whether you’ll drive), so you can book without delay.

For questions, the organizers list the Ticket Sales Management Center at 0570-01-8789 (weekdays 10:00–17:00, Japanese).

In short: reservations are now open — lock in your route
