Showa Denko Dome Ōita

Resonac Dome Oita is a retractable roof, multi-purpose stadium in the city of Ōita in Ōita Prefecture on Kyushu Island in Japan.

The stadium was built for Ōita Prefecture, which still owns it. Design was led by the famous architect Kisho Kurokawa and his firm Kisho Kurokawa Architect & Associates, and construction was carried out by a construction group led by the Takenaka Corporation. The stadium opened as Oita Stadium in May 2001.

In 2006 it was renamed Kyushu Oil Dome, as a result of a sponsorship deal with Kyushu Oil. In early 2010, the stadium was renamed Oita Bank Dome when sponsorship shifted to Oita Bank. In early 2019, the stadium was renamed Showa Denko Dome Oita after Showa Denko acquired naming rights. On 1 January 2023 Showa Denko merged with another another company, forming Resonac Holdings Corporation, and the stadium was given its current name.
