| The Sumo Museum (相撲博物館, sumō hakubutsukan) is an institution located in the Ryōgoku Kokugikan arena in Sumida, Tokyo. The museum is managed by the Japan Sumo Association. The museum was opened in September 1954 when the Kuramae Kokugikan was completed. Its collection were based on materials collected over many years by Tadamasa Sakai, a well known sumo fan and first director of the museum. Its missions are to prevent the loss of materials related to sumo by collecting them and displaying them in the premises of the museum. In January 1985, when the Ryōgoku Kokugikan opened, it moved to its present location.[2] |
