Yu-no-tani onsen, Hoshi-no-yu is half way up Mount Aso. The bath is a large rock bath with plenty of room for everyone. The water is nice and warm without being too hot, but not warm enough to stay in for hours. There is separated woman's and men's area with shelves to put the clothes on just inside the entrance. In front of the hot spring is a large open area where it is possible to camp in a little tent.
Yu-no-tani onsen is located half way up Mount Aso. From Kumamoto city take route 57 towards mount Aso. Next take route 325 towards Choyo village. Before getting into Choyo village make a left turn and go up mount Aso. Follow this road all the way to the end. You will see a very large hotel, and probably think you went up the wrong road, but keep going right past the holes main entrance, and you will get to a large open space. Here you will find Hoshi-no-yu.
