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 (九州石油ドーム, Kyūshū Sekiyu Dōmu), as a result of a sponsorship deal with Kyushu Oil [ja]. In early 2010, the stadium was renamed Oita Bank Dome (大分銀行ドーム, Ōita Ginkō Dōmu) when sponsorship shifted to Oita Bank [ja]. In early 2019, the stadium was renamed Showa Denko Dome Oita (昭和電工ドーム大分) 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.^[2]

The stadium is primarily used for football, and is the home field of J.League club Oita Trinita.

The stadium originally had a capacity of 43,000. After the 2002 FIFA World Cup, 3,000 movable seats on the track were removed, giving the stadium its current capacity of 40,000.
