In the Aoba ward of Yokohama, Kanagawa Prefecture, Yokohama Aoba Onsen Kirakuri Bettei offers sodium-chloride thermal water at 41°C (106°F). An indoor bath, an outdoor rotenburo bath and a sauna are available.
Insider tip — Yokohama's Aoba ward is one of the city's most forested and affluent residential areas — the name 'Aoba' (青葉 — blue-green leaves) perfectly captures the lush canopy that covers this western Yokohama hillside district. 'Kirakuri Bettei' (きらくり別邸 — sparkling villa/retreat) suggests a refined bathing experience; Aoba draws dark sodium-chloride thermal water from deep Yokohama geological formations. The Tama Hills forest and the Tsurumi River valley provide exceptional urban nature just 30 minutes from central Yokohama.
