Hiroshima Big Arch, Sports stadium in Asaminami Ward, Japan

Hiroshima Big Arch is a multi-purpose stadium in Hiroshima's Asaminami Ward, built in 1992. A single tier of seats rings the 107 m by 73.3 m natural-grass pitch and the eight-lane 400 m track. Only the main stand carries a roof: a broad, shallow white arch of rectangular panels, said to evoke the Hiroshima Peace Memorial's A-Bomb Dome, with an angled grid frame projecting at one end.

The stadium opened in September 1992 with the AFC Asian Cup, where Japan beat Saudi Arabia 1–0 in the final. It was built as the main venue for the 1994 Asian Games and the 1996 National Sports Festival. Sanfrecce Hiroshima made it their main home from 1994, and the club played there through 2023.

The nickname Big Arch comes from the arched roof over the main stand, said to evoke the Hiroshima Peace Memorial's A-Bomb Dome. The stadium's naming rights have changed hands: Edion held them from 2013, and Hot Staff Hiroshima took over the name in March 2024. Concerts are also held here alongside athletics and football.

The stadium sits in Hiroshima's northwestern Nishikaze Shinto area, about five minutes on foot from Koiki-koen-mae Station on the Astram Line. Buses from Hiroshima Bus Center stop at A City Chuo, roughly ten minutes away. The main stands are uncovered apart from the arched main-stand roof, so check the weather before choosing a seat.

The stadium served as home to a football club for three decades before the team relocated to a newer facility. This long association became part of the location's identity within the city.
