Nozawa Hot Spring Ohyu
Hot Spring Overview
Also known as “Inukai no Go-yu,” this historic bathhouse has remained unchanged since the Edo period and stands as a symbol of the village at the heart of the hot spring town.
The building features a high ceiling and two separate baths—one with hot water and one with lukewarm water—allowing visitors to enjoy different temperatures.
The hot spring water, classified as a simple sulfur spring, is said to soothe tired muscles and relieve stress and tension. The source of the spring is Ōyu (Ōyu Onsen).
Please note: The hotter bath is extremely hot, so be sure to pour plenty of water over yourself before entering to avoid discomfort.

Nozawa Onsen is an easily accessible hot spring village, reachable by car or public transportation.
Despite its accessibility, it holds a unique distinction—it is the only village in Japan with "Onsen" (hot spring) in its name, and the hot spring culture is deeply woven into the fabric of daily life.
Scattered throughout the village are 13 communal bathhouses (soto-yu), each with a simple and modest design—just a space to remove your shoes and a small changing area. Rather than being tourist facilities, these baths are considered "baths for daily life," intimately connected to the local community.
These communal baths are maintained and managed by a group of local residents known as “Yunakama”, who distribute hot spring water from the source free of charge to each facility.
Though Nozawa Onsen is a popular destination, its enduring culture of communal bathing and its deep local traditions give it the authentic charm of a hidden onsen.
