The shaguma (赤熊, "red bear") was a type of headgear worn by the officers of the Imperial Japanese Army troops in the Boshin War (1868–69). The headgear was composed of long, dyed yak hair and held in place by a chin-strap.
Shaguma indicated officers from the Tosa Domain, whereas haguma (白熊, "white bear") indicated officers from the Chōshū Domain, and koguma (黒熊, "black bear") indicated officers from the Satsuma Domain, respectively. However, the elite jinshotai corps of Tosa were known to have worn the shaguma as well.
