Yamabushi
are Japanese mountain ascetic hermits. They are generally part of the syncretic  religion, which includes Tantric Buddhist, Shinto, and Japanese Taoist elements. Their origins can be traced back to the solitary Yama-bito and some  (saints or holy persons) of the eighth and ninth centuries. According to American writer Frederik L. Schodt:

Clothing and items 

Yamabushi usually wear and bring the following clothes and items with them:
 Yuigesa (), a harness or sash adorned with pom-poms
 Kyahan (), sandals made from straw
 Tokin () which is a small hat-like adornment worn at the front of the head
 Shakujō (), a metal rod, held in their hands
 Oi (), backpack
 Horagai (), a conch shell, which they blow like a horn
