Fukuoka Kokusai Center, Sports venue and convention center in Hakata-ku, Japan

Fukuoka Kokusai Center is a convention hall in Hakata-ku, Fukuoka, opened in October 1981. The building has one basement level and three above ground, with a 3,425 m² arena on the first floor, a 1,627 m² gallery on the second and a capacity of up to 10,000 people. Its wide facade carries a long band of dark glass windows above pale walls, and white lettering reads "福岡国際センター" over "FUKUOKA KOKUSAI CENTER".

The complex opened on October 15, 1981, following designs by architectural firm Azusa Sekkei and quickly became one of the main event venues in Fukuoka Prefecture. Since the early eighties, it has served as a host for numerous national and international sporting events as well as concerts by well-known artists.

The facility hosts the November Grand Sumo Tournament, where visitors can watch traditional ring wrestling matches and ceremonies that have been part of Japanese culture for hundreds of years. During tournament days, many attendees dress formally out of respect for the event and observe the precise rituals performed by referees and athletes.

Visitors can reach the site via Gofukumachi Subway Station and transfer to regular bus services that connect to Tenjin and Hakata stations. The halls inside are accessible through stairs and elevators, allowing guests with limited mobility to move around the building.

The hall's 56-by-56-metre arena floor is the size of a full sumo ring layout, and the ceiling above it is a suspended four-sided pyramid modelled on the traditional sumo canopy, hung with two pale circular emblems and a white banner with a red circle. The building is set to be rebuilt or relocated after about 45 years of use.
