Visitors come not only for the historic value but also for the peaceful mountain scenery, where hot springs flow naturally and time seems to move slower.
Hot Springs: Pure and Timeless Relaxation
Natural Flowing Hot Spring from the Source
Keiunkan’s greatest treasure is its natural hot spring water, flowing directly from the source without any recycling or added chemicals.
