APPI + Shimokura Shared Tree Run Zone Rules

The tree run zones are some of the largest in Japan and have great quality snow. However, these areas are for advanced skiers and snowboarders only as they carry more risks than normal slopes. Please follow the rules and recommendations below to enjoy the area safely.

Area Operations
