Oyada Onsen (Myojin no Yu) is located in Adachi ward, Tokyo. Its sodium-chloride thermal water reaches 41°C (106°F). The bathhouse has an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — Adachi ward in northeastern Tokyo is one of the city's most genuinely working-class areas — known for its authentic shitamachi (old downtown) character, the Senju merchant quarter (once Edo's busiest post town on the Nikko Kaido highway), and excellent local street food. 'Myojin no Yu' (明神の湯 — divine spring) draws the signature dark black water from deep Tokyo sedimentary formations; the ward's Kitajukken River linear park is a beautiful urban promenade through this underappreciated corner of Tokyo.
