Zao in Yamagata Prefecture is one of the largest mountain resorts in the Tohoku region.
In winter, Zao is a mecca for winter sports, and many tourists come to enjoy the "juhyo," or tree ice formed by snow and ice on the trees.
Juhyō is formed when ice and snow repeatedly land on the leaves and branches of the Aomori Todomatsu (Abies mariesii) trees that live nearby.
It is a rare sight that can be seen only in some mountain areas of the O-u Mountains, as it forms only when special conditions such as temperature, wind direction, and snowfall are met. They are called "snow monsters" because of their beautiful yet monstrous appearance.
The best time to view the rime is usually from late December to early March, with the peak season from late January to early February.
The best viewing spot is the juhyo field that stretches from the Juhyo Kogen Station of the Zao Ropeway to the Jizo Sancho Station.
If you take the ropeway, you can enjoy an aerial view of the juhyo field below.
Near the Jizo Sancho station, visitors can experience the powerful scene up close. There is also an observatory where you can enjoy a 360° panoramic view and a restaurant where you can enjoy the view indoors. Visitors can also enjoy the unique experience of skiing or snowboarding alongside the juhyo. Check out the limited-time-only illumination events.
Zao is also famous for its observatory, which has been selected as a sacred place for lovers, and Zao Onsen, a natural hot spring with free-flowing spring water, so take your time to enjoy sightseeing in Zao in winter.
