A faithful reconstruction of the Meiji-era public bath, with stained glass and Kutani-ware tiles. No washing stations — you simply soak, the old way. The combined ticket with the adjacent Sōyu is the better deal.

The communal 'sōyu' of Yamanaka, praised by the poet Bashō as one of Japan's three finest baths. Men's and women's halls stand in separate buildings across the street; the deep, hot (~43°C) pool is the signature. 6:45 am to 10 pm, ¥500. Bring your own soap.

The public bathhouse at the heart of Yamashiro Onsen's 'Yu-no-gawa' square in the Kaga hot-spring region, a spa 1,300 years old. In Kaga communal baths are called 'sōyu', and even ryokan guests walk over in yukata. The entrance reuses the gate of the old Yoshinoya inn; inside is spacious and clean, with one big tub of fresh undiluted water (sodium-calcium sulphate-chloride) flowing freely. Adults ¥500, open 06:00–22:00, closed only on the morning of the 4th Wednesday. A ¥900 combined ticket includes the 'Ko-sōyu' opposite (¥700), a recreation of the Meiji-era bathhouse with Kutani-ware tiles and stained glass — comparing the two is the classic plan. Soap and shampoo are sold, not provided. About 10 minutes by bus from Kaga-Onsen Station.

Day bathing at Shirasagiyu Tawaraya, an inn of roughly 800 years overlooking the Kakusenkei gorge. The waters of Yamanaka Onsen, praised in a haiku by Matsuo Bashō, can be taken in open-air baths opening onto the valley. Day bathing is by advance reservation only, 9:00–11:00 and 15:00–18:00, at ¥1,500 (tax included) for adults, ¥1,000 for elementary pupils and free below age 2, with a towel set (bath towel and hand towel) included. The two great baths, Kakusen and Kajika, switch between men and women morning and afternoon. Overnight guests come first, so busy days are not accepted, and the private great baths are not available for day use.
