Chōzuya/Temizuya, Chōzubachi and Tsukubai

A chōzuya or temizuya (手水舎^?) is a Shinto water ablution pavilion for a ceremonial purification rite known as temizu.

Water-filled basins, called chōzubachi, are used by worshipers for washing their left hands, right hands, mouth and finally the handle of the water ladle to purify themselves before approaching the main Shinto shrine or shaden (Japanese: 社殿). This symbolic purification is normal before worship and all manned shrines have this facility, as well as many Buddhist temples and some new religious houses of worship. The temizuya is usually an open area where clear water fills one or various stone basins. Wooden dippers are usually available to worshipers.
Originally, this purification was done at a spring, stream or seashore and this is still considered the ideal. Worshipers at the Inner Shrine at Ise still use this traditional way of ablution.

A chōzubachi (手水鉢^?) is a vessel originally designed to keep water for rinsing one’s mouth and cleansing one’s body before entering the sacred precincts of a Shinto shrine or a Buddhist temple in Japan.
A derivative vessel is the tsukubai (つくばい^?), an important feature of the Japanese tea ceremony found within the yard surrounding the tea house.

A tsukubai (蹲踞^?) is a small basin provided in Japanese Buddhist temples for visitors to purify themselves by the ritual washing of hands and rinsing of the mouth (perform ablutions). This type of ritual cleansing is also the custom for guests attending a tea ceremony.

Tsukubai are usually of stone, and are often provided with a small scoop, laid across the top, ready for use. A supply of water is provided via a bamboo pipe called a kakei.
