Lit. "half arm." A sleeveless short undergarment for aristocratic men. From the Nara through the early Heian periods, hanpi had short sleeves, but from the mid-Heian period when chōfuku 朝服 (court dress) evolved into a Japanese style, hanpi developed into a sleeveless straight-edged form and were called sokutai 束帯. A small strap, kohimo 小紐, made of the same materials as the hanpi, was tied at the waist. The wasureo 忘緒 (forgetful strap), made of *ra 羅 (gauze), was attached from the left of the waist through the kohimo. Hanpi were made of silk *aya 綾 and ra. Hanpi used for *bugaku 舞楽 (court dance and music) costumes were made of luxurious materials. The *Shōsōin 正倉院 preserves brocade *nishiki 錦, wax-resist dyed rōkechi 臈纈, tie-resist dyed *kōkechi 纐纈, and clamp-resist dyed kyōkechi 夾纈 hanpi. From the Kamakura period, brocade, embroidered, and tie-dyed hanpi were popular.
