Nozawa Hot Spring Shinyu
Hot Spring Overview
Located at the northern end of the hot spring village, near the entrance to Tsutsuji-yama Park, this bathhouse is affectionately known as the "Five-Colored Hot Spring" due to its water changing color—from milky white to emerald green to clear.
Also referred to as "Reisen Mayu" (Sacred Spring Mayu), it is famous for its excellent water quality and especially for having an abundance of mineral deposits (yunohana).
The hot spring source is Shinyu.

Historic unique spring
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.
