Maishima Baseball Stadium, Baseball stadium in Maishima Sports Island, Japan.

Maishima Baseball Stadium is a baseball ground on Maishima Sports Island in Osaka, opened in 1996. Its dark-soil infield and natural-grass outfield measure 100 m down the lines and 122 m to center, with seating for 10,000. A yellow tubular arch rises over the concrete facade, which bears the lettering "舞洲ベースボールスタジアム" and "MAISHIMA BASEBALL STADIUM".

Maishima Baseball Stadium was completed by the city of Osaka in 1996, built with the aim of serving as a baseball venue had the city's bid for the 2008 Summer Olympics succeeded; the bid did not. Until March 31, 2016, the city owned it and a Mizuno group consortium managed it. In 2016 the Orix group bought the stadium for 64 million yen and moved its farm team's base there.

The stadium serves as a gathering place for local baseball communities, hosting school teams and amateur leagues that draw fans from across the region. It shapes how people in the area connect through the sport.

You can reach the stadium from Nishi-Kujo Station by taking city bus number 81, which stops near the main entrance at Maishima Chuo Station. Allow extra time for travel and check bus schedules in advance since service times may vary.

The scoreboard was funded in part by the Japan Lottery Association, and a message reading "a gift from the lottery" appears in its lower right corner. The stadium has six lighting towers, and its stands have no roof at all, so sea winds from Osaka Bay blow across the seating throughout games.
