The stadium was built on the site of the former Yokohama Cricket Club, which was the first cricket club established in Japan.
It is the only professional baseball stadium in Japan that utilizes a bowl-shaped design rather than a traditional tiered grandstand.
The ground was historically significant as the site of the 1896 Yokohama Park baseball match, considered one of the earliest recorded games in Japan.
The stadium's turf is a hybrid artificial grass designed specifically to reduce impact on players' joints.
During night games, the stadium lighting system is fully automated to adjust brightness levels based on real-time atmospheric conditions.
The facility features 'BayStars-themed' stadium seats that are wider than average to accommodate modern visitor comfort standards.
Yokohama Stadium, known locally as Hamasta, serves as the home field for the Yokohama DeNA BayStars professional baseball team. Located within the heart of Yokohama Park, it was the first stadium in Japan to feature a bowl-shaped seating configuration. The venue gained international prominence as a primary site for baseball and softball events during the 2020 Summer Olympics. It has a total seating capacity of approximately 34,000 spectators. The stadium underwent significant renovations in 2020 to expand its seating capacity and improve concourse accessibility. Its field dimensions are 94 meters down the lines and 118 meters to center field. The stadium complex includes multi-level seating sections and specialized corporate box areas.
The upper deck viewing area provides a panoramic view of the entire field with the Yokohama skyline in the background.
Purchase tickets well in advance through the official online portal, as games frequently sell out.
Bring a small towel to participate in the 'towel spin' tradition during the BayStars' victory songs.
Dress in the team color, blue, to blend in with the local fan base.
Do not attempt to purchase tickets at the gate on game days, as they are rarely available.
The stadium is primarily active during the professional baseball season from spring through autumn; closed for events or maintenance during winter months.
Avoid standing during play to block views; wait for breaks or home runs to celebrate actively.
