Matsunoyama Onsen: Hot Spring Guide, Prices & Access

Matsunoyama Onsen is a hot spring in heavy-snow country, celebrated as one of Japans finest medicinal waters. Its source is said to be ancient seawater sealed underground, and the dense, mineral-rich water warms the body from within. The surrounding landscape of terraced rice fields is a sight in itself. It is counted among Japans three great medicinal hot springs, alongside Kusatsu and Arima.

Highlights

A quiet spa street dotted with traditional inns, along with beautiful terraced fields and satoyama scenery all around, gives the town its appeal. The deep snow makes for a striking winter view. The town also has an easy-to-reach foot bath, handy for a rest between strolls.

Enjoying the Seasons

Spring buds, deep-green summer hills, golden autumn terraces, and profound winter snow bring dense, vivid nature in every season.

Access and Basic Information

Reach it by bus or car from Matsudai Station on the Hokuhoku Line. The route from the Tokamachi direction is scenic as well. The water is a sodium and calcium chloride spring with high salinity, giving it excellent heat-retaining qualities.

Practical Travel Notes

As a base for day-trip bathing, the town has the Taka-no-yu public bath, where you can enjoy the dense chloride water in indoor and open-air pools. Admission is around 600 yen for adults, and it generally opens from about 11 a.m. to 8 p.m., with Thursdays listed as closed. A little uphill lies Nastebyu Yu-no-yama, whose open-air bath with fine views is popular. Because the water is salty, drink plenty afterward and keep your soaks to a comfortable length. In this heavy-snow region, check road and bus conditions before a winter visit.

A Quick Tip

The water is highly concentrated, so drink plenty of fluids afterward and keep your soaks to a comfortable length. A strong chloride spring also tends to leave the skin feeling moist after bathing.
