(⊙ _ ⊙) The first soup in the world, pure groundwater, can take a bath. Fees vary, ranging from 80 to 200 an hour, clean and hygienic! Japanese forest hot springs are large and interesting. The pools are different, but they are not underground water, nor clean, and sometimes the water is not very hot. Tickets 190 or so. Think for yourself! I suggest the first soup in the world.
