In the traditional Japanese bathing culture, visitors enter a serene space to unwind and cleanse the body and mind. Before bathing, guests typically remove their clothing and wear a provided loincloth or towel. The bathing area is typically divided into separate sections for men and women. Water is sourced from natural hot springs, and bathing is a communal experience where guests soak and relax in warm, mineral-rich waters.
Insider tip — Michinoku Onsen taps a volcanic sulfurous spring in the remote mountains of northern Akita, an area dotted with hidden hot spring inns. The milky white water carries the distinct sulfur scent characteristic of active volcanic springs. Snow blankets the surrounding forest from November through April, making the outdoor bath experience particularly dramatic in winter. Guests often extend their stay to hike the beech forests of nearby Shirakami-Sanchi.
