Shima Onsen Sekizenkan – Genroku-no-yu (day use)
四万温泉 積善館「元禄の湯」（日帰り入浴）
Founded in 1691 and regarded as Japan's oldest surviving hot-spring inn building, this Shima Onsen institution in Gunma stands across a red bridge; the main house, said to be one of the models for the bathhouse in Spirited Away, is an Important Cultural Property. The celebrated Genroku-no-yu, built in 1930 in Taishō-romantic style, has five tubs set into a stone floor lit by arched windows, with water welling up from below. Shima's sulphate water is counted among Japan's three great baths for digestive ailments and can be drunk. Day use 10:00–17:30 (last entry 17:00), ¥1,500 with face towel, covering Genroku-no-yu, the mixed rock bath and private baths. Tattoos accepted if covered with stickers. About 40 minutes by bus from Nakanojō Station to the Shima Onsen terminus.

Sainokawara Open-Air Bath
A 10-minute walk west of Kusatsu's Yubatake, at the far end of Sainokawara Park, lies one of Japan's largest open-air baths. Around 500 m² of pool brims with strongly acidic water, open to the surrounding forest. Snow in winter, fresh green in summer, illuminations at night. There are no washing stations — this is purely for soaking.
Otakinoyu
A large day facility where you can try Kusatsu's traditional 'awase-yu' — a row of wooden tubs at rising temperatures, entered in order. Indoor baths, rotenburo, sauna, plus rest and dining areas make it good for half a day. About 10 minutes' walk from the Yubatake, or a short bus ride. Admission ¥1,200 (2026); three-bath pass with Gozanoyu and Sainokawara ¥2,100.
Gozanoyu
Right in front of the Yubatake, a wooden recreation of the Edo–Meiji communal baths. Wood and stone bath halls alternate between men and women daily, with two sources (Yubatake and Bandaiko). The upstairs hall looks down on the Yubatake.
