Katayamazu Onsen Sōyu
片山津温泉 総湯
An all-glass communal bath on the shore of Lake Shibayama in Katayamazu, part of the Kaga onsen cluster, designed by architect Yoshio Taniguchi. The lake-facing 'Kata-no-yu' and garden-facing 'Mori-no-yu' swap between men and women on odd and even days; for ¥500 you get the Hakusan peaks and the lake to yourself. The salty chloride water keeps you warm long after. Open from 6:00 to 22:00, with a café upstairs (closed Thursdays) selling onsen eggs. About 10 min by bus from Kaga-Onsen Station.

More in this area
Wakura Onsen Sōyu
Salty water rising from the Noto sea, for ¥500. The community anchor of the onsen town, still operating after the 2024 Noto earthquake. Open-air and indoor baths plus a rest area.
Yamashiro Onsen Ko-Sōyu
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.
Yamanaka Onsen Kiku-no-yu (Sōyu)
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.
