A sumo gyōji wielding a gunbai

The gunbai (軍配?, short for 軍配団扇 gunbai-uchiwa) military leader's fan (in old Japan); umpire's fan (in sumo wrestling)[1] is a type of Japanese war fan.


Gunbai, from the Sino-Japanese roots meaning "military-apportioned [fan]", were a specialized form of fan used by samurai officers in Japan to communicate commands to their troops. Unlike regular fans, gunbai were solid, not folding, and usually made of wood, wood covered with metal, or solid metal.

It is also a key accessory of a gyōji in professional sumo. The main use is at the end of a bout, when the gyoji decides the victor and points the gunbai to either the east or west position (each wrestler is assigned to start from either the east or west position each tournament day). Reflecting this, the gyōji's decision itself is often informally referred to as a "gunbai". If this is called into question and the shimpan (umpires) hold a consultation, a decision to uphold the gyōji's judgement is announced as gunbai-dōri (軍配通り), literally "according to the gunbai", while a decision to overturn it is gunbai-sashichigae (軍配差し違え), literally "gunbai mispointed."

In Popular Culture[edit]

In the Naruto series, two leading antagonists Obito Uchiha and Madara Uchiha are regularly seen carrying and wielding a purple and a brown gunbai, respectively, the latter was known for having great expertise in using it.

In Team Fortress 2, a melee weapon for the Scout class is the Fan O'War, which is described as a "Level 5 Gunbai." Although it is weak on its own, any target hit by this weapon will receive 35% more damage for 15 seconds, and during this period, the Fan O'War deals Critical Hits to the target.

In Tomb Raider Definitive Edition, the gunbai is a discoverable relic.
