Nipro Hachiko Dome
Stadium in Ōdate, Akita, Japan
The Nipro Hachiko Dome (ニプロハチ公ドーム, Nipuro Hachikou Dōmu) is a large wooden stadium in Ōdate, Akita, in northern Japan. The stadium covers an area of 12,915 m2.[1] It was completed in June 1997 and is made from 25,000 Akita cypress trees which are covered with a special double Teflon-coated membrane. This allows enough sunlight into the stadium so that during the day no artificial lights are needed.[2] The stadium is principally used for baseball games,[3] but thanks in part to its removable grandstands, the stadium can also be used for other sports and events.[4] Nipro, a Japanese medical equipment manufacturing company, purchased the naming rights to the dome in 2017.[5]
