2. About 大倉ダム
What is Ōkura Dam?
Ōkura Dam is a gravity dam built to regulate water flow in the surrounding river system of Miyagi Prefecture. While official records list the dam’s exact height and altitude as unknown, its primary purpose is to support local water management and provide a scenic reservoir for recreation.
History & Significance
The dam’s construction dates back to the post‑war era, a period when many Japanese prefectures invested heavily in infrastructure to boost agriculture, flood control, and hydro‑electric potential. Though Ōkura Dam is modest compared to larger structures like the Miyagi Prefectural Dam, it remains an essential piece of the region’s water network.
Why It Matters to Travelers
- Scenic Reservoir – The calm lake formed by the dam mirrors the surrounding forest, creating picture‑perfect reflections especially at sunrise and autumn.
- Gateway to Waterfalls – Within a 5‑km radius you’ll find several waterfalls that are popular among hikers and photographers.
- Peaceful Atmosphere – Unlike the crowded tourist spots in central Sendai, Ōkura Dam offers a quiet, contemplative environment ideal for picnics, meditation, or a leisurely stroll.
