妙法湯

Myohoyu is a sento two minutes from Shiinamachi Station, renovated in 2019 around soft water, including what it calls Japan's first soft-water carbonated silky bath, and every bath uses nano-microbubbles. The saunas are hot, set to 110 °C for men and 100 °C for women, and the 16 °C soft-water cold bath is up to a metre deep on the men's side. Sauna entry with bath and towels costs ¥950. Open 15:00–25:00, closed Mondays; tattoos are welcome.

Monday: Closed; Tuesday to Sunday: 3:00 PM – 1:00 AM (next day)
