Misato Onsen Maneki no Yu, in Takasaki, Gunma Prefecture, offers sodium-chloride thermal water at 40°C. The bathhouse pairs an indoor bath with an outdoor rotenburo and a sauna for a classic Japanese onsen break.
Insider tip — Takasaki produces more Daruma dolls than any city in Japan — the red papier-mâché wish-fulfillment figures sold at New Year shrines across the country are made here in workshops that have operated for centuries. The Maneki no Yu (Beckoning Cat Bath) embodies this local culture of good fortune and hospitality. Takasaki is also Gunma's commercial hub and the gateway to the famous onsen valleys of Kusatsu, Ikaho, and Shima — fill in one eye of your Daruma when you arrive, the other when your soak is complete.
