In the northern reaches of Kyoto, where the ancient capital's urban fabric gradually gives way to hillside temples and traditional machiya streetscapes, Funaoka Onsen stands as one of the city's most celebrated neighbourhood bathhouses — a sento and onsen that has served the residents of the Kuramaguchi district for generations. The bicarbonate waters flow at 35 °C with a balanced neutral pH of 7.0, their characteristic mineral softness making the skin feel smooth and the body noticeably light after bathing.

Funaoka Onsen is as much a cultural landmark as a thermal site, its ornate carved wooden entryway and period interior preserving the aesthetic of early Showa-era public bathing. The bicarbonate composition — gentle and softening — is well suited to the contemplative pace of Kyoto life. Visitors arrive alongside locals in equal measure, drawn by both the bicarbonate waters and the rare experience of bathing within walls that feel inseparable from the city's layered history.

Insider tip — Stay well hydrated before and after your bath in bicarbonate water at 35°C in Japan.
