Katayamazu Onsen: Day-Use Hot Spring Baths & Prices

One of the spas of the Kaga hot spring district, Katayamazu spreads its streets along the shore of a lake called Shibayama Lagoon. Across the water rises the Hakusan range, and the surface that shifts in mood between morning and evening makes this a strikingly scenic spa. Its glass-walled Soyu bathhouse is the symbol of the town.

Highlights

The Soyu, designed by the world-renowned architect Yoshio Taniguchi, is largely sheathed in glass and seems to melt into the lagoon and the green of the forest. Inside are two baths, the Kata-no-Yu overlooking the lake and the Mori-no-Yu wrapped in forest green, which alternate between men and women by the day. The lakeside promenade is also pleasantly laid out.

Enjoying the Seasons

Spring brings cherry blossoms along the shore, and summer fireworks famed across the region color the lagoon. Autumn tints the surrounding hills, while winter offers a fine contrast between the snow-capped Hakusan range and the lake.

Access and Basic Information

About 10 minutes by bus from JR Kaga Onsen Station, or roughly 7 minutes by car from the Katayamazu interchange on the Hokuriku Expressway. The Soyu runs from around 6 in the morning until about 10 at night, with the Kata-no-Yu and Mori-no-Yu baths alternating between men and women each day. Admission is around 500 yen for adults, with childrens rates also set. There is no fixed closing day, though occasional closures occur, so please confirm fees and hours with the official information.

Practical Travel Notes

The color of Shibayama Lagoon changes greatly between morning and evening, so visiting twice at different hours is recommended. A morning bath offers a calm lake surface, while an evening bath frames the dusk against Hakusan, each with its own character. Since the two baths swap by the day, staying two nights lets you enjoy both. In summer the lagoon fireworks are the local specialty, drawing crowds along the shore. About 10 minutes by bus from Kaga Onsen Station, it makes an easy base for touring the Kaga spas together with Yamashiro, Yamanaka and Awazu. Nearby are Kutani porcelain kilns and the Nakaya Ukichiro Museum of Snow and Ice. The budget is modest for a day-use bath at the Soyu, while a lakeside inn lets you take in the waterside scenery.

A Quick Tip

Shibayama Lagoon changes greatly between dawn and dusk. Try both a morning and an evening bath to enjoy how the color of the water shifts. Because the baths swap between men and women each day, a two-night stay lets you enjoy both.
