Chōzu

Purification Rituals

Chōzuchōzu / 手水

The ritual act of purifying hands and mouth with water before worship.

Chōzu refers to the act of cleansing hands and mouth at a temizuya. Anciently, worshippers would purify their bodies in rivers before sacred rituals, but as this was impractical for all visitors, the simplified practice of hand and mouth rinsing became standard.

The word "chōzu" evolved from "temizu" (hand water) through phonetic change, and it also became a euphemism for the bathroom, similar to "restroom" or "lavatory" in English. In the world of tea ceremony, guests purify their hands at a "tsukubai" (crouching basin) before entering the tea room — demonstrating how the Japanese reverence for cleanliness permeates culture far beyond religious settings.
