Tsukimiyu Onsen is a bathhouse in the Setagaya ward of Tokyo. It offers neutral-pH thermal water alongside an indoor bath, a rotenburo-style outdoor bath and a sauna, right in the heart of the Japanese capital.
Insider tip — Tsukimiyu Onsen is a neighbourhood sento (銭湯) or onsen in Setagaya, one of Tokyo's greenest residential wards. The urban onsen of Setagaya draw their water from deep geothermal aquifers. 'Tsukimi' evokes moon-viewing — a poetic atmosphere for an evening bath.
