Hot Spring / Hot Spring Bath

A famous big open-air bath at the highest point in Zao Onsen town. An open-air bath for men and women made alongside the mountain stream, with capacity for 200 people. An open construction surrounded by Zao’s nature, it is a popular spot for enjoying the hot spring or peaceful walk through the woods. The hot spring water is of the highly acidic sulfur variety, also called the “beauty maker.” It is closed from December to the following March. Take the Yamako Bus to its last stop in the “Zao Onsen” direction.

Yamagata Main Areas


Although often overlooked, Yamagata prefecture by no means lacks appeal: the Yamadera temple trail through the mountains, deliciously tender Yonezawa wagyu, and over 100 steaming hot springs, most notably Zao Onsen, await visitors. When winter comes, the snowcapped peaks become dotted with skiers by day and onsen-goers by night, while summer brings the celebration of juicy Yamagata cherries.
