Togoshi Ginza Onsen: Tokyo’s Black-Water Sento Beside the Shopping Street

Togoshi Ginza Onsen sits just off the long Togoshi Ginza shopping street, handy for a soak after browsing the local shops. It is a public bath with a natural black-water spring, not a resort spa: admission is ¥600, while the bathhouse adds an unusually useful rooftop bathing area and sauna to its compact city setting.

Two bathhouses, one changing rota

Inside are two distinct sides, called Hino-yu and Tsuki-no-yu. Each has its own mix of baths and design; the gender assignment changes, so you cannot count on a particular layout on a particular weekday. Both sides have access to black spring water. If one specific setup matters, call the bathhouse on 03-3782-7400 before heading over.

The building was redesigned around a “new and old” contrast, with contemporary materials alongside familiar sento details such as a painted mural. The architect’s project notes date its completion to April 2007. That combination feels especially at home next to a shopping street that still works as a local high street rather than a purpose-built tourist strip.

What admission costs—and the sauna-price discrepancy

Adult bath admission is ¥600. The Shinagawa bathhouse association lists the sauna package at ¥750 including admission, but dated 2026 visitor records report paying ¥950 for a sauna visit with face and bath towels. If you plan to use the sauna, allow for the higher amount and confirm the current price by phone; the public listings do not agree.

Opening hours are 3 p.m.–1 a.m. Monday through Thursday and Saturday. On Sundays and public holidays, there is also a morning session from 8 a.m. to noon. Friday is the regular closing day. Togoshi Station on the Toei Asakusa Line is about three minutes away; Togoshi-ginza Station on the Tokyu Ikegami Line is around five minutes on foot.

A useful stop before or after the shops

The Sunday morning opening is the detail that changes the day’s shape. You can bathe first, then explore the shops as they open, or end an afternoon of browsing with a soak. On other days, the late closing time suits an evening outing—but this is a public bath, not a place to stay overnight.

Black spring water can make the steps and bath edges harder to see. Take your time entering, especially if you are unfamiliar with dark-water baths. For a first visit to any Tokyo sento, our public-bath basics cover what to bring and how the bathing routine works.
