Opened in 1991, the stadium is being redeveloped to meet the 2019 Rugby World Cup standards. It will also be home to the sevens for the 2020 Tokyo Olympic Games.

Including patches of grass behind one end, the capacity currently stands at 24,000 (9,232 seats) but it will be converted into an all-seater venue for the 2019 Rugby World Cup. Large electronic screens and floodlights will also be installed.
