In this paper we investigate the form of the spa village in Edo period, by doing the case study of the Atami spa, Shizuoka. In this spa village, hot spring inns were called the Yuko. They governed for this village, because they made a monopoly of the Oyu hot spring, which was the main hot spring in Atami. We study about for the space and community structure of this spa village in Edo period, by showing the existence of the Yuko.
