Tennen Onsen Miurayu Gumyoji is located in Gumyoji, Yokohama, Kanagawa Prefecture, Japan. Its sodium-chloride thermal water emerges at 41°C. An indoor bath, an outdoor rotenburo and a sauna round out the facility.
Insider tip — Miurayu at Gumyoji sits in the shadow of Gumyoji-ji Temple (弘明寺), founded in 738 AD — one of the oldest Buddhist temples in the Kanto region, housing a nationally designated Important Cultural Property. The spa's dark Yokohama mineral water and the ancient temple create an unusually contemplative urban onsen neighborhood; the Gumyoji shotengai covered shopping street is one of Yokohama's most charming.
