Katayamazu Onsen sits on the southern shore of Lake Shibayama in Kaga City, Ishikawa Prefecture, on the Sea of Japan coast. Part of the celebrated Kaga Onsen group — four historic hot spring towns that together form one of the Hokuriku region's most distinguished spa clusters — Katayamazu holds a particular character shaped by its lakeside setting. The still waters of Shibayama-gata, fringed by reeds and reflecting the moody skies of the Hokuriku winter, give this onsen a contemplative, almost melancholic beauty.
The spring water, bicarbonate-type and alkaline at pH 8, flows at a comfortable 40 °C, ideal for the extended soaking sessions that Japanese bathing culture prizes. The soft, slightly silky quality that bicarbonate waters impart to the skin has long made Katayamazu a favourite among ryokan guests seeking the full sensory experience of a traditional Japanese bath. Freshest seafood from the Japan Sea, served in the lakefront inns, completes an evening that feels entirely of this coast.
