Shaguma, Haguma and Koguma was a type of headgear worn by the officers of the Japanese Imperial troops in the Boshin War. The headgear was quite peculiar, involving the used of long, colored, "bear" hair. The "Red bear" (Shaguma) wigs indicate officers from Tosa Jinshotai, the "White bear" (Haguma) wigs officers from Chōshū, and the "Black bear" (Koguma) wigs officers from Satsuma.
