Sumo Museum, Sports museum in Ryogoku, Japan
The Sumo Museum occupies a single 150 m² exhibition room at the far end of the right side of the Ryogoku Kokugikan arena in Sumida, Tokyo. Its entrance is a wide glass doorway in a dark wall, with a metal band of Japanese text above it; inside, lit display cases hold woodblock prints, banzuke ranking sheets and keshō-mawashi ceremonial aprons. Four curators run the room, which has no permanent display.
The museum opened in 1954 to preserve and document sumo wrestling's evolution across centuries of Japanese history. Its establishment marked a formal effort to safeguard this time-honored sport for future generations.
The collection displays traditional kesho-mawashi ceremonial aprons and historical documents that reveal sumo's deep connection to Shinto rituals and practices. You can see how these spiritual ties are woven into the fabrics and records on view.
The museum sits at the far end of the right side of the Ryogoku Kokugikan, and its entrance near the association offices stays open when no event is held; the front-entrance door is closed then. It shuts on Saturdays, Sundays, holidays and over New Year, but opens daily during tournaments, when only arena ticket holders may enter.
The museum occupies only about 150 m² at the far end of the Kokugikan's right side, with a single exhibition room and four curators, so some regulars at the arena have never set foot inside. Wrestlers also use it: former Arawashi consulted its audiovisual archives to refine his technique.
