Daini Satonoyu is one of the onsets (hot springs) in the Happo Onsen group. This is probably my favorite of the bunch because it is HOT! Last time I went it was over 43 degrees. The washing area is right next to the bath so it is nice and warm there too. There are some onsen I won’t go to when I am feeling chilly because the washing area is just too cold. No problems here. The springs at the 4 Happo Onsens are high alkaline waters with a PH of 11, which means the water feels soft and makes your skin silky smooth. No rotenburo (outdoor bath), no windows, no view. Nothing fancy just good quality water at the right temperature (for me).
