Yanagiyu

A cash-only Shinjuku Ward sento heated with well water, which it also uses for its cold plunge. Its high-power jet bath is popular, and it has seated electric (denki-buro), bubbling (vibra) and reclining baths plus standing showers, with 100-yen coin-return lockers in the changing room. It sits right by the station and bus stop, just behind the southeast exit of Ushigome-Yanagicho Station on the Toei Oedo Line, about 30 seconds away.
