Oyu, at the center of the hot-spring town, is a wooden bathhouse built by Nadachi carpenters from local cedar, with an upper roof that drives out the steam, the tourism bureau writes. The outdoor baths have been a shared asset of the villagers, protected since the Edo period by a bath-fellowship system, and villagers maintain and manage all 13 of them.
