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 the north of 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]


Interior view

The roof was made from 25,000 Akita Cypress trees which were aged over the course of 60 years.[4] This wooden framework is covered with a special double Teflon-coated membrane made from translucent fluorethylene resin-coated fibreglass.[5] This membrane is very strong and light. The stadium is location in a region of Japan that it subjected to heavy snowfall of 2 to 3 m (6.6 to 9.8 ft). Because of this, the dome itself also has an aerodynamic design to resist strong winds and heavy snowfall.[2] Buildup of snow on the roof is prevented by circulating warm air between the 2 Teflon-coated membranes, this shakes off the snow and allows the stadium to be used in all weathers.[4]
