The purpose of this paper is to clarify the characteristic and origin of the techniques of "ARAI" by analyzing the tools. "ARAI" is a traditional purification cortex technique in Japanese wooden architecture, using wooden buckets and brooms of straw. To confirm the characteristic of the technique, we investigated the names, the uses, the shapes, and the making methods of the tools. Moreover, we considered the origin of "ARAI" from the three viewpoints of acquisition, technique, and symbols of the tools. These viewpoints shed light on different characteristics of tools and lead three origin theories that "ARAI" derives from a farmer, a plasterer, or a ritual.
