Dating from 1931, this gem of a neighbourhood sento features a beautiful mural of the wooden arched bridge Kintai-kyo on the bathhouse wall. The amber-hued water is packed with skin-friendly minerals, though you'll need to brace yourself — the cooler of the two pools sits at a scalding 45 degrees Celsius. It's the kind of place where the local regulars have been coming for decades, and the old tile work and wooden fittings tell the story of Tokyo's vanishing public bath culture.
