A beautiful onsen by the river. There is a semi open hot bath overlooking the river. According to some people we met the water is very good here. Its slightly milky and a bit yellow and sulphurous. We felt great after a soak here.
So far this is our favourite onsen. Very comfortable and relaxing.
You can stay the night at this onsen in the hotel or you for 800 yen you can visit. They open nice and early at 8AM. There are a number of other onsens in the area to try out too.
