Zao Onsen Ski Resort is one of Japan's oldest ski areas, located in the Yamagata Prefecture. The resort is globally recognized for its 'snow monsters' (juhyo), which are trees encased in heavy ice and snow caused by Siberian winds. The terrain spans multiple slopes, catering to beginners and experts, with a vertical drop of nearly 900 meters. The area sits at the base of Mount Zao and features a traditional onsen village with acidic, sulfur-rich hot spring waters. The resort operates an extensive ropeway system providing access to the summit. Skiing and snowboarding conditions are typically available from mid-December through early April. The village itself is known for its centuries-old history as a hot spring retreat. The resort provides access to diverse trails, including a long, winding course that traverses the mountain landscape.
