Yubara Onsen
Along the river, rows of ryokan line the banks, and steam rises in the stillness of the surrounding mountains. Yubara Onsen is a hot spring town that spreads along the clear Asahi River, where you can enjoy smooth, alkaline hot spring waters.
This place is all about peace and relaxation.
It's not a busy, touristy hot spring street.
The most famous part is the open‑air mixed bath where you soak right by the river.
Coming in winter feels especially nice. The water is very hot but not harsh.
The surroundings feel very natural, and at night it's almost completely quiet.
Perfect if you want to clear your mind and take your time soaking.
