Access

How to reach GREEN×EXPO 2027, based on the official Visitor Transport Implementation Plan (v2, Feb 2026). The venue has no adjacent station, so shuttle buses from four stations are the main access — all by advance reservation.

Venue
Former Kamiseya Communications Facility site, Asahi / Seya Ward, Yokohama
By train + shuttle
Reserved shuttle buses from 4 stations: Seya, Mitsukyo, Tokaichiba (Sotetsu/JR) and Minami-machida Grandberry Park (Tokyu). Buses run ~90/day on quiet weekdays up to ~160/day at peak. Yokohama / Shin-Yokohama may also be used to spread crowds.
By car / parking
Venue parking (advance reservation): ~5,900 spaces north + ~600 south, ~1,000 for motorcycles, ~200 accessible. At peak, off-site Park & Ride (Aeon Mall Yamato / Ito-Yokado ~500, Sagami-ono ~200). Bicycle parking ~1,700.
From airports
From Haneda / Narita, head to central Yokohama, then transfer to the Sotetsu / JR / Tokyu line toward one of the 4 shuttle stations.
