Hasunuma Onsen

6-16-11 Nishi-Kamata, Ota-ku, Tokyo

About

A 2-minute walk from Hasunuma Station (Tokyu Ikegami Line) and a 10-minute walk from JR Kamata Station. Founded in 1944 and reopened after renovation in 2017, every bath is filled with natural onsen water (a sodium chloride-bicarbonate cold mineral spring). The cold bath is fed directly from the source, and there's also a carbonated bath and a sauna. The lobby features a distinctive digital-signage "pond" display. One dedicated parking space is available in front of the building (report to the front desk when using it), and a partner coin parking lot (Coin Park Nishi-Kamata 6-chome) offers a ¥400 service voucher on presentation of a parking receipt. The official FAQ accepts tattooed guests, with the condition that "guests who cause trouble for other customers or staff may not use the facility." Closed every Tuesday.
