Cauldron ceremony. A ceremony in which water is boiled in a large cauldron and then sprinkled over participants and worshippers with bamboo fronds. It bears some relation to other heat-generating rites such as firewalking and is sometimes used to enable a miko to become possessed by the kami. A stylised version of the rite which originated at Ise forms part of the kagura repertoire, as yudate kagura.
