Mashu and Kussharo Sea of Clouds Tour

Take a tour to Viewpoint 3 of Lake Mashu and see a vast sea of clouds over the Kussharo caldera, the largest caldera in Japan. If the season and conditions are right, you'll see another sea of clouds covering Lake Mashu, and if you're extra lucky you might even see mist drifting over Lake Mashu, creating a magical scene. *If booking at short notice, please inquire by phone to Tourism Teshikaga: 015-483-2101
