2. About 横川ダム
What is Yokogawa Dam?
- Type: Multipurpose dam (water supply, flood control, recreation)
- Location: Namie, Fukushima Prefecture, Japan
- Coordinates: 37.599213 N, 140.905321 E
- Official page: 横川ダム (Wikipedia)
Built in the latter half of the 20th century, Yokogawa Dam plays a crucial role in regulating the flow of the Yokogawa River, which feeds agricultural lands and supplies drinking water to surrounding communities. While the exact height and altitude remain undisclosed in public records, the dam’s modest scale blends seamlessly into the natural landscape, allowing visitors to enjoy unobstructed views of the forested hills and the gentle ripple of the reservoir.
Historical Significance
Yokogawa Dam was constructed during a period when Japan was rapidly expanding its infrastructure to support post‑war economic growth. In Fukushima, the dam helped mitigate flood risks that historically plagued the coastal plain, especially during the rainy season and typhoon events. Over the decades, the reservoir has also become a valuable ecological habitat, supporting a variety of fish species and migratory birds.
In recent years, the dam has taken on a symbolic role in the region’s recovery after the 2011 Great East Japan Earthquake and the subsequent nuclear incident. Namie, once an evacuation zone, is now gradually reopening to tourism, and Yokogawa Dam serves as a quiet reminder of resilience and renewal.

5. What to Expect
Scenic Walks
A well‑maintained 2 km loop trail circles the reservoir, offering multiple viewpoints:
- East Viewpoint: Overlooks the dam’s spillway; perfect for sunrise shots.
- North Picnic Area: Equipped with benches, trash bins, and a small kiosk selling local snacks (onigiri, grilled corn).

The trail is mostly flat, making it accessible for families, seniors, and casual hikers.
Wildlife & Photography
The reservoir’s calm waters attract kingfishers, herons, and Japanese cormorants. In autumn, you may hear the calls of migrating white‑eared night herons. Photographers love the mirror‑like reflections of the surrounding forest, especially during early morning mist.
Cultural Touches
Near the dam’s entrance, a modest information board (in Japanese and English) explains the dam’s construction, its role in flood control, and the local ecosystem. Occasionally, the Namie Town Office organizes short guided tours in Japanese, so consider learning a few basic phrases or bringing a translation app.
