💡 Tips for Visitors

The ryokan is remote and best reached by taking a sightseeing boat from Lake Shikotsu's eastern shore or hiking the lakeside trail (about 2.5km). Cash is recommended as card payment may be limited. Day-visit bathing is available, but staying overnight offers the full traditional ryokan experience with kaiseki meals. Basic English support may be limited, so consider using a translation app. The outdoor baths are mixed-gender during certain hours, so check the schedule if you prefer single-gender bathing times.
