I am so sorry for the blurry sight. As I posted a few days ago, each hot spring was named and was the namesake of the language of indigenous people of Hokkaqido, Ainu.
This bath tub was named "Unukarunoh" which means "See you again !" in Ainu Language.
It seems that I was so comfortable after jogging around the valley in the cold air and so was my camera, I think. All the photos were too blurred out. This is the biggest bathtub in the largest building in the facilities.
