    The most famous spot here is the Sunayu bath by the river.

    It's a mixed open‑air bath, totally free and really rustic.

    The first time you see it, you might feel a bit shy, but honestly everyone is just soaking naturally and minding their own business.

    The water is on the hotter side. It feels amazing in winter, but in summer you really need to be mentally prepared.

    If you prefer something more low‑key, the hot springs at the nearby ryokan are more comfortable.

    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.

    Very relaxing vibe.

    The onsen street is small, but it’s really pleasant to walk around.

    The famous open‑air Sunayu bath has a great atmosphere, and you can hear the sound of the river while you soak, which is super soothing.

    Overall it doesn’t feel commercialized at all.

    Great for people who want a quiet hot spring experience and a slow, easy day.
