GREEN×EXPO 2027 Shuttle Bus & Parking Guide: Reservations Open Sept 18 — Stations, Fares, Fees

Getting to GREEN×EXPO 2027 (the 2027 International Horticultural Exposition in Yokohama) is about to become much more concrete. According to the organizers’ official announcement (the press release dated July 17, 2026), three reservation systems open 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. That date 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. This guide covers everything officially confirmed so far about the shuttles and parking — fares, fees, and how the system works — plus what to prepare before September 18. For the full ticket picture, see our tickets page; for the overall access framework, see the access page.

Three reservations open on September 18, 2026

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

Reservation	Opens	Status
Timed-entry (admission ticket date & time)	Friday, September 18, 2026	Date confirmed; procedure TBA
Shuttle bus (four stations)	Friday, September 18, 2026	Date confirmed; procedure TBA
Parking (passenger cars etc.)	Friday, September 18, 2026	Date confirmed; procedure TBA
Parking (group buses)	Monday, August 3, 2026	Already open

One thing to keep firmly in mind: what’s confirmed is the start date, not the booking procedure. The organizers say the details of how to reserve will be published on the official website once decided, and the opening time on September 18 has not been announced either. The official FAQ states that the July 17 announcement is all the information available for now. Anything you read elsewhere about “how booking will work” is speculation at this stage — wait for the official follow-up.

That said, some rules for timed-entry reservations are already fixed. Reservations cover the entire expo period, and 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; and even after using all three changes, you can still enter on the day if same-day slots are available. The full walkthrough and preparation tips are in our date reservation guide.

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:

Category	Standard	Accessibility discount
Adult	¥200	¥100
Child	¥100	¥50

“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.

[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.

Station	Distance	Est. journey time	Boarding bays	Buses per hour (off-peak – peak)
Seya	~2 km	~10 min	3	~20–40
Mitsukyo	~4 km	~15 min	2	~10–30
Minami-machida GP	~4 km	~20 min	4	~20–60
Tokaichiba	~6 km	~25 min	4	~20–60

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.

While it’s confirmed that advance reservations open on September 18, the operational details — whether every bus requires a reservation, whether same-day seats will exist — are still to be announced. We’ll update this article as news lands.

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.

Station	Line	Best for
Seya	Sotetsu Main Line	Direct from Yokohama Station or the Ebina area on the Sotetsu Line
Mitsukyo	Sotetsu Main Line	Sotetsu users who want to dodge crowds at Seya
Minami-machida Grandberry Park	Tokyu Den-en-toshi Line	Coming from Shibuya / Futako-Tamagawa; a large shopping complex at the station makes waiting easy
Tokaichiba	JR Yokohama Line	Coming from Machida / Hachioji, or transferring from the Shinkansen at Shin-Yokohama

If you live along the Sotetsu Line, choose Seya or Mitsukyo — they’re neighboring stations, so you can flexibly pick whichever has more open slots. From 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 can transfer at Shin-Yokohama to the JR Yokohama Line for Tokaichiba. For a deeper station-by-station comparison, see our four-station shuttle comparison.

Once reservations open on September 18, the key is to think of your entry slot and your shuttle as a set. Securing an entry time is only half the job if no shuttle seat matches it. 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:

Category	Weekday	Weekend / holiday / peak
Passenger car (standard)	¥5,000	¥7,000
Passenger car (accessibility rate)	¥2,500	¥3,500

Category	Fee
Motorcycle	¥2,000
Group bus (standard)	¥10,000
Group bus (accessibility rate)	¥5,000

“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.

[August 2026 update] The 3rd edition transport plan also confirmed the parking capacity: the North lot holds about 5,690 standard spaces plus roughly 200 accessible spaces and 110 priority (“omoiyari”) spaces; the West lot adds about 540 standard spaces. Motorcycle parking (about 1,000 spaces) is in the North lot only. Approach routes assume the Tomei Expressway (Yokohama-Machida IC) and Route 16 Hodogaya Bypass (Kamikawai IC).

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

The booking procedure for general parking is not yet announced — only the September 18 start date is confirmed. Group bus parking is the exception: its reservations already opened on August 3, 2026.

As a rough cost comparison: a round trip on the shuttle (¥400 per adult) plus train fare is clearly cheaper for one or two people, while a family of four or more driving directly from home may find the ¥5,000 weekday parking rate starts to compete.

Three things to prepare before September 18

Even with the procedure unannounced, the officially confirmed requirements tell you what you can do now.

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 once booking opens. 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 act the moment the official announcement drops.

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

In short: September 18 is the day you lock in your route

Shuttle buses (¥200 adults, four stations) and parking (¥5,000 weekdays / ¥7,000 weekends) both open for advance reservations on Friday, September 18, 2026, the same day as timed-entry ticket reservations. The detailed procedure and opening time are still to be announced, so the smart move is to prepare now — secure tickets, note your ticket ID, choose your dates and station — and watch the official site for the follow-up.
