Otomeyu Onsen, in Tokyo's Edogawa ward, offers thermal sodium-chloride water at a gentle 37°C, well suited for longer soaks. The bathhouse also features an outdoor rotenburo and a sauna.

Insider tip — 'Otomeyu' (maiden's bath) is an urban sento in Tokyo's eastern Edogawa district, near the Chiba border. Like many Tokyo sentos, it taps dark 'kuroyu' (black water) artesian hot springs — sodium-chloride rich and deeply warming. A quintessential Tokyo neighbourhood bath experience.
