Act 1 Hot springs
This is the largest map and the beginning of the story,you'll find the most onsens here, since there are 9. Here is the general map with the springs indicated in blue.
Be careful however, one of the springs must be unblocked by talking to the manager of the hostel in the village of Hiyoshi, perched high above the waterfalls and basins. The icon does not appear on the map without it talking to them.
Act 2 Hot springs
A little less generous than the first one, the Act 2 still has 6 hot springs to be found. We suggest you find them all before finishing the act, otherwise you will have to wait a while to be able to bathe in them.
Act 3 Hot springs
This region being very cold, there are only 3 springs.
