倉下の湯 (kurashita-no-Yu) is perhaps my favorite onsen in Hakuba. Mind you, it is not everyone’s favorite. Some people don’t like the color of the water, others are put off by the rusty smell. However, I love the yellowish-grey iron-rich water here. As the sign on the wall proudly exclaims “this is real onsen water, straight from the spring” where nothing is added and none of it gets recycled. Hakuba has 3 types of hotspings. The alkaline springs in Happo make you feel real good on the outside as they do wonders for the skin. While this super potent iron and sulphur solution does wonders for your insides.
