Gunbai
A visible decision in a crafted object.
A gunbai (軍配), also called a gunbai uchiwa, is a rigid fan associated historically with military command and today especially with the gyōji of sumo. On the ring, its most important function is to make the referee’s indication visible. As an object, it may carry lacquer, inscriptions, decorative motifs and a tassel connected with the user’s rank. Some examples have documented histories of transmission between referees. These functions need to be kept distinct: the fan is an instrument used in judging, a crafted object and sometimes an heirloom. An old command fan is not automatically a fan that was used in a sumo bout.

01
A command object with a wider history
The ICU Museum’s account of an Edo-period mirror decorated with a gunbai motif explains the fan’s earlier military command association. Its appearance as a motif also shows a life beyond the battlefield or ring. A depiction of a gunbai and a surviving working fan are different kinds of evidence.
02
The fan makes a judgement visible
The Association describes the gunbai as the implement used to indicate the outcome clearly. Its direction is part of the referee’s communication with the arena. The signal belongs to a procedure that can include review by the ringside judges; the physical object does not make a call immune to correction.
03
Shape, material and decoration
The Association lists woods such as zelkova, oak and rosewood, with lacquered surfaces carrying crests, sun-and-moon imagery or inscriptions. It notes that decoration is not restricted to one prescribed design. The familiar oval form should therefore not be mistaken for a single standard artwork reproduced for every official.
04
Three ways to read one fan
Appearance alone cannot supply every part of an object’s history. The functional and historical questions are complementary.
- Gesture
- How the referee is using the fan at that moment.
- Tassel
- A prescribed indication of professional rank.
- Surface and provenance
- Decoration, ownership and any documented transfer.
05
An inherited fan has a chain of custody
The Sumo Museum’s centenary display identified a fan used by the first Shikimori Inosuke. Other fans have passed through later generations, sometimes under several professional names. Such an object needs its own provenance. The age of the office, the age of the fan and the date of its use by a particular referee are not interchangeable.
06
A working tool can become a museum object
The 2006 Sumo Museum exhibition brought together fans, attire, inrō and calligraphy. That grouping places the gunbai within the wider material world of refereeing. For an antique or a museum label, the decisive questions are what is recorded about manufacture and use, and whether a claimed sumo connection is documented rather than inferred from the fan’s outline.
