Supervisor・Tsuyoshi Mizuguchi

He began practicing sumo in sixth grade, later advancing to Hotoku Gakuen High School and Ritsumeikan University before joining the Kasugayama stable to enter professional sumo. After retiring in 2016, he appeared in a popular subscription-based drama series titled Sanctuary. Currently, he runs his own YouTube channel, “Osumo Gucchan-neru,” where he shares videos on sumo training, techniques, and his experiences from his time as a professional wrestler.

The Gunbai is a fan-shaped ceremonial tool held by referees in Japanese sumo. Its origins date back to the Sengoku period, where it served as a military command fan for warlords. Over centuries, the Gunbai evolved into a symbol of authority and judgment in sumo, representing not only fair play but also the etiquette and tradition of Japanese culture.

Origin and History of the Gunbai

The history of the Gunbai dates back to the Sengoku period. At that time, warlords used the Gunbai Uchiwa on the battlefield to give orders for troop positioning and movement. This fan served as both a tool for calm decision-making and a symbol of the commander’s authority.
During the peaceful Edo period, the Gunbai was no longer used in battle but instead in formal ceremonies and rituals. Eventually, the custom emerged for sumo referees to carry the Gunbai, and it continues to this day.

Role of the Gunbai in Sumo

In sumo, the Gunbai is used by the referee to declare the winner. When a bout ends, the referee points the Gunbai toward the winning side to make the judgment clear. This movement is an important gesture to show the winner not only to the wrestlers but also to the audience.
The Gunbai is also used before a bout begins, as the referee raises and lowers it to signal the start of the match. This helps maintain the flow of the entire contest.
