Tennen Onsen, known as Hinata no Yu, is located in the Higashiyodogawa ward of Osaka. Its sodium-chloride thermal water reaches 41°C (pH 7.3), with an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Hinata no Yu (Sunny-Side Bath) brings light and warmth to northern Osaka's Yodogawa district — a characteristically unpretentious working neighborhood far from Dotonbori's neon. The Yodo River's northern banks bloom with cherry blossoms every spring in one of Osaka's most beloved local hanami settings, far from tourist crowds. The artesian sodium-chloride waters here tap ancient marine deposits beneath Osaka's urban sprawl — dark, mineral-rich, and deeply warming on the cool evenings when river winds move across the Yodogawa embankments.
