A hachimaki (鉢巻) (headband, lit. "helmet-scarf")^[1] is a type of Japanese headband, usually made of red or white cloth, typically featuring a design of kanji at the front.

The origin of the hachimaki is uncertain, but the most common theory states that they originated as headbands used by samurai, worn underneath the kabuto to protect the wearer from cuts^[1] and to absorb sweat.^[2] Inspired by samurai, kamikaze pilots in World War II wore hachimaki while flying to their deaths.^[3]

In modern Japan, hachimaki are often emblazoned with slogans and red circles reminiscent of the flag of Japan. They serve the function of absorbing sweat during physical activity, so they are often worn by sportspeople. Hachimaki may be worn to showcase Japanese nationalism or sporting pride.^[1] They are also associated with the Bōsōzoku subculture in Japan.^[2] In Western popular culture, hachimaki are stereotypically associated with martial artists.^[1]
