Ota Onsen

Aso-region onsen village treated as a single inn — a wooden bath-hopping pass (nyūtō tegata) opens three rotenburo of your choice across the participating ryokan.

Pastoral basin under Mount Yufu, famous for ryokan with private rotenburo, craft shops along Yunotsubo Street, and the morning mist over Lake Kinrin.

Eight distinct onsen districts (Beppu Hatto) — Kannawa, Myoban, Kankaiji, Hamawaki, Kamegawa, Horita, Shibaseki, central Beppu — and more spring sources than any other city in Japan.
