Extreme Weather Spurs Renewed Interest in Dome Stadiums Across Japan
Following a retro wave back toward open air ballparks over the past two decades, Japan is once again seeing renewed interest in dome stadiums, as relentless summer heat and torrential downpours force a reconsideration of stadium design.
On June 2, Chiba's municipal government, the Chiba Lotte Marines baseball team, and Aeon Mall announced plans to develop a new dome stadium. Located on a municipal parking lot a kilometer from the current facility, the new venue is scheduled for completion around 2034. Team owner Tamatsuka Gen'ichi stressed the need for a roofed structure due to recent extreme weather events.
Japan has seen a surge in 35°C or higher temperatures, with Isesaki, Gunma Prefecture, hitting a record 41.8°C on August 5, 2025. Torrential downpours have also increased. Despite initial concerns over high costs, public opinion favored an indoor venue, citing player safety, spectator comfort, and year-round event hosting. While a retractable roof like that of Hokkaidō's Eisentheim Field was initially requested, budget constraints made a fixed structure more feasible.
Zozo Marine Stadium, opened in 1990, has historically experienced strong winds and the smell of Tokyo Bay. The new stadium aims for year-round multipurpose use. Aeon Mall sees business potential by integrating with the stadium. Meanwhile, Tokyo's redevelopment plans include a multipurpose arena at the former Tsukiji Market site, alongside a new indoor rugby stadium in Meiji Jingū Gaien district.
The district will also feature a new baseball stadium for college competitions, alongside other facilities.
