Zao onsen is a traditional Japanese hot spring town nestled in the
mountains of Yamagata in the Tohoku region. Zao Onsen’s waters are among
the most acidic in the country and are know as
“Springs of Beauty”
Guests can relax at a number of public bathhouses, day spas and outdoor
baths. To experience the unique charm of Zao, we recommend visiting in
winter. Make sure to visit Zao’s "Snow Monsters" - the result of a
unique atmospheric condition that causes fir trees to take on the shape
of monsters. Zao is a perfect winter destination that combines skiing,
hot springs and sightseeing.
