Takasaki Onsen, known as Sakura no Yu, is a hot-spring bath in the city of Takasaki, Gunma Prefecture. The sodium-chloride water, at 41°C, supplies an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Sakura no Yu blooms in Takasaki, a city synonymous with the round red daruma good-luck doll that symbolises perseverance. The Gunma plain spring draws from saline aquifers, and after your soak you can visit the workshops where artisans still hand-paint the classic papier-mache daruma figures.
