- Japan's largest spring output
- Free foot bath around the clock
- Illuminated at night
A 24-hour foot bath beside Yubatake
Yukemuri-tei is a pavilion-style foot bath right next to Yubatake. The strongly acidic water — Yubatake yields about 4,000 litres a minute — is cooled through wooden channels, and at night you can soak while watching the illuminated Yubatake. At pH ~2 it stings cuts and tarnishes silver jewellery.
Tips
- Seats are limited and queues form by day; early morning, mealtimes and right after the illumination are quieter.
- Wear trousers you can roll above the knee.
- Within 1 min: the yumomi show at Netsunoyu (paid) and the free Shirahata-no-yu communal bath.
Getting there
About 5 min on foot from the bus terminal, inside Yubatake square.
Before you go
- Strongly acidic water — rinse off afterwards, avoid long soaks, and remove silver jewellery.
- Last entry is 30–60 minutes before closing.

More in this area
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.
