Ichinomata Onsen

Welling up along the Ichinomata River in Toyota, Shimonoseki, this mountain hot spring has long been called the quiet retreat of Kanmon. Its alkaline water has a distinctively silky feel, and the inns set in the tranquil valley invite a slow, restful stay.

Highlights

In early summer, countless fireflies swirl by the riverbank in a dreamlike display known across the country. Paired with the silky beauty spring, it is an experience found only here.

Enjoying the Seasons

Buds open on the hills in spring, fireflies glow in early summer, the valley reddens in autumn, and winter brings the local wild-boar hot pot alongside warming baths, so the mountain seasons shift with quiet richness.

Access and Basic Information

It is about a thirty-minute drive from the Ozuki interchange on the Chugoku Expressway. Set deep in the hills, it is most easily reached by car.

A Quick Tip

The fireflies are at their best on early-summer nights. Staying over and soaking in the bath while you wait is a treat in itself.
