    Zao Onsen large open-air bath

Zao Onsen is said to have opened in 110 AD and is a hot spring area at the west foot of the 1900-year-old Zao mountain range.

The spring water is strongly acidic and effective against skin diseases. It is also called “Hime no Yu” (“The princess’s water”) because it has a whitening effect and is known as a hot spring for beautiful skin.

You can enjoy beautiful scenery all year round at this nationally famous tourist resort, and in winter it is crowded with visitors wanting to see the snow monsters or just enjoy winter sports.
