Tsukubai

Traditional Japanese ritual washbasin

In Japan, a tsukubai (蹲踞) is a washbasin provided at the entrance to a holy place for visitors to purify themselves by the ritual washing of hands and rinsing of the mouth. This type of ritual cleansing is the custom for guests attending a tea ceremony or visiting the grounds of a Buddhist temple. The name originates from the verb tsukubau, meaning "to crouch" or "to bow down", an act of humility. Guests attending a tea ceremony crouch and wash their hands in a tsukubai set in the tea garden (roji) before entering the tearoom.
