About

A natural hot spring facility in Okudo, Katsushika Ward, drawing an iodine-sodium-chloride hot spring from 1,720m underground. It features open-air baths, walking baths, family baths, and three sauna types (high-temperature, medium-temperature, and steam). As it is some distance from the nearest stations, a free shuttle bus runs from Shin-Koiwa, Kameari, Kanamachi, and Aoto stations.
