three-strand harness or sash with pom-poms (Shugendō)
A specialized ritual garment worn by practitioners of Shugendō, a Japanese mountain ascetic tradition. The term refers to a distinctive sash or harness made of three strands and decorated with pom-poms.
The mountain ascetic sets out on training wearing a yui-gesa.
The tassels of the yui-gesa are brightly colored, adorning the practitioner's attire.
The term combines 結 (yui, 'tying' or 'binding') and 袈裟 (kesa, 'Buddhist surplice'), referring to a tied or knotted sash. The exact historical origin is uncertain, but it is associated with Shugendō ritual attire.
