Onikobe Onsen Todoroki Ryokan

A small inn inside Kurikoma Quasi-National Park, where the outdoor bath is a rock-lined mixed rotenburo (露天風呂) with a low central divider that makes it more comfortable for everyone. Reviewers who have come back five times mention the views from the rooms and how genuinely relaxing the soak is, the kind of place that earns repeat visits through quiet quality rather than flashiness.
