The Zao Snow Monsters, also known as Juhyo, are unique natural formations found in the Zao Onsen area of Yamagata Prefecture, Japan. These snow-covered trees are created by heavy snowfall and strong winds, which coat the trees in thick layers of snow and ice, giving them a ghostly appearance. The phenomenon typically occurs during winter, attracting tourists and photographers. Visitors can explore the Zao Snow Monsters through various ski trails and hiking paths. The best time to see these formations is from late December to early March. The area also offers stunning views and a chance to experience the beauty of winter in Japan.
