The Numaura Observatory is the parking lot at the end of the slope after entering the ocean side from the entrance of the Numaura Campground. Looking at the mountain side from the hill, you can see the Otatomari Swamp below and Mt. Looking toward the ocean, you can see the mainland of Hokkaido beyond the Sea of Japan.
