A hagoromo (羽衣, lit. "Feather Robe") is a long, thin shawl depicted as the mythical of tennin (天人) in Japanese mythology. Its visual form is based on the Chinese pibo (披帛), a light silk scarf worn by women in ancient China, particularly during the Tang dynasty.
The concept of celestial beings wearing flowing, floating shawls originated in Chinese folklore. The earliest known "feather robe" tale appears in the 4th-century text Soushen Ji (搜神记), and the motif appears in the legend of the Cowherd and Weaver Girl (牛郎织女) and the myth of the Seven Fairy Maidens (七仙女). This motif later spread to Japan, where it evolved into the specific legend of the hagoromo (羽衣伝説)—a story in which a tennin descends to earth, her feather robe is taken, and she is unable to return to heaven.
Despite being thin, it is often depicted being able to remain upright in the air on its own.
Buddhist deities' hagoromo-like shawls are called "天衣" (Chinese: tian yi, Japanese: tenne, ten'e, or ten'i). On Danbooru, tian yi is currently tagged as hagoromo.
Distinguishing hagoromo, tianyi and pibo
Use hagoromo for the magical feather robe of Japanese tennin, as seen in the legend of the hagoromo (羽衣伝説). For Chinese contexts, two visually similar but culturally distinct garments exist:
Use pibo (披帛) when the long, flowing shawl appears on any figure—divine or mortal—in Chinese Buddhist art, Daoist iconography, historical settings, or xianxia (仙侠) fiction. This includes: bodhisattvas and feitian (飞天) in Dunhuang murals; Daoist immortals; and secular women in Tang dynasty paintings. Because of this broad usage, pibo itself does not inherently signal "supernatural" status—a bodhisattva's pibo and a court lady's pibo can look identical.
Use tianyi (天衣) when the specific concept of a "celestial robe" is visually emphasized and a distinction is desired—particularly if the garment is seamless, self-illuminating, or explicitly depicted as a non-material, heavenly vestment. Tianyi carries a stronger connotation of divinity than pibo.
When in doubt, pibo is the safer, more general tag for any Chinese-style floating shawl. Reserve tianyi for cases where the celestial nature of the garment is visually unmistakable.
