A certain hot spring inn has received high reviews across multiple travel sites. It seems they offer a special service in their private open-air bath. Apparently, there is something inside the “bubbles” and you have to guess what it is. There are apparently a variety of bubbles, from fluffy to crunchy to slimy… I wonder what kind of game they play in the private open-air bath???
