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.
