Tucked in Tokyo's Oshiage district, this bathhouse draws sodium-chloride water heated to 41°C. Indoor pool, sauna and massage services make it a convenient relaxation stop near Tokyo Skytree.
Insider tip — Oshiage Onsen Daikokuyu is a neighbourhood sento in the Oshiage district, a stone's throw from Tokyo Skytree, blending old shitamachi culture with a modern landmark backdrop. The sodium-chloride water drawn from deep below the Kanto plain is heated and softened, leaving skin nourished after a soak. The establishment preserves classic sento architecture with tiled changing rooms and a wooden bucket culture. It is a perfect antidote to tourist fatigue after a day exploring Asakusa and the tower.
