"We went here by walking since it was snowing. Bicycle rentals were not available when its snowing. Even without the usual blue waters. The view was still so breathtaking. Loved how the surrounding was covered with snow. The pure white view was a sight to see too. Would love to revisit again in a different season to see the shima blue color."

The Engineering Marvel: Shima Dam
The dam's primary function is to manage water resources, ensuring stability for the region. The controlled release of water also contributes to the aesthetic appeal of the area, particularly when viewed from the scenic loop. Understanding its purpose adds another layer of appreciation for this man-made structure within a natural setting.
While the dam itself is an engineering marvel, its most celebrated aspect is the artificial lake it creates. This lake, Lake Okushima, is the source of the renowned 'Shima Blue' color, a visual spectacle that draws many visitors seeking natural beauty and impressive landscapes.
Experiencing 'Shima Blue': Lake Okushima
Visitors often describe the 'Shima Blue' as breathtaking and a highlight of their trip. Even when the water isn't its signature blue, such as during snowy conditions, the lake retains a serene beauty. The sheer scale of the lake, formed by the dam, contributes to its dramatic appearance and the overall scenic appeal of the area.
To best appreciate the 'Shima Blue,' it's recommended to visit during daylight hours, especially when the sky is bright. The changing light throughout the day can subtly alter the intensity and shade of the blue, offering different perspectives for those who spend extended time by the lake.
Beyond the Dam: Nearby Attractions

While not explicitly detailed for Shima Dam itself, the mention of canoeing in one TikTok video suggests the potential for water-based recreation in the broader Shimagawa river area. Exploring the local villages and hiking trails can also offer a deeper immersion into the local culture and environment.
