Located in the Joshin'etsu-Kogen National Park, Shimagawa Dam is a popular tourist spot near Shima Onsen, known for the stunning "Shima Blue" waters of Lake Okushima. The dam offers panoramic views of the surrounding landscape, especially vibrant during the autumn foliage season. Visitors can walk across the dam, explore the park below, and even obtain a dam card from the management office (weekdays only, or by mail). The area features well-maintained parks, clean restrooms, and parking facilities, making it an ideal destination for nature lovers and sightseers. Be mindful of the potentially dizzying height if you're afraid of heights!
