Ikarashi Cospo is the heart of Sea of Japan surfing, producing consistent waves when Siberian winter storms sweep across from the northwest. The beach features white sand, dunes, and gorgeous views of Sado Island, with mellow waves that work for all levels. The water is shallow enough to touch bottom, making it ideal for beginners, while winter swells can produce fun right-handers across multiple peaks. The local community is welcoming, without the localism found at more famous breaks.
