Ibusuki Onsen Unagi Kohan

A quiet lakeside inn on the shores of Lake Unagi in Ibusuki, with a semi-mixed open-air bath (han-konyoku, 半混浴) said to be the only one of its kind in the area. The water runs lukewarm, which is perfect for a long, unhurried soak. It's a simple, no-frills place, tatami rooms, self-service futons, but the lakeside calm and genuine hot spring water make it worth the trip for those who like their onsen experiences unhurried.
