Also called Hashiriyu Gongen 走湯権現. A deity associated with a hot spring which wells up on Izusan 伊豆山, a hill of 166 m in Shizuoka Prefecture close to the sea coast. A shrine was raised to the deity in the early 9th century. In the late Heian period an Esoteric Buddhist mikkyō 密教 temple called Hannyain 般若院 was built on Izusan. The sculpture of Izusan Gongen that was the principal image of Hannyain survives. He originally held a mace shaku 笏 and a halberd hōbō 宝鉾. He wears a court hat, court robes, and kesa 袈裟 (Buddhist robes). This combination expresses particularly well the unity of Buddhism and Shinto shinbutsu shūgō 神仏習合 (see *honji suijaku 本地垂迹). In the Kamakura period, Izusan became a mountain used for ascetic practice shugendō 修験道 (see *En no Gyōja 役の行者), and was linked with Hakone 箱根 as a pilgrimage destination, receiving government patronage. Izusan remained well known as a shugendō sacred mountain until the early Meiji period, when the site was made Shinto and the Buddhist objects scattered. A Buddhist manifestation *honjibutsu 本地仏 of Izusan Gongen is the Thousand-armed Kannon *Senju Kannon 千手観音.
