There is also a very fine business hotel located next to onsen building. Hot spring pass included with hotel stay. Both are conveniently located near T49.
Very slimy, very hot alkaline water. One of the nicer onsen I have visited with outdoor tub, walking onsen, sauna (with a TV!) and cold pool. Everything very clean and modern, staff very friendly.
This is first hotel in Japan I have had glass cabin stand up shower. Kobo Daishi clearly heard and answered my prayer as I was dreaming of such a shower just the day before! Basic, yet comfortable, stylish and perfect location on Henro Michi.
