2. About 島地川ダム

Description & Location

• Name: 島地川ダム (Shimatani River Dam)
• Type: Dam 🏗️
• Location: Tokuyama, Yamaguchi Prefecture, Japan
• Coordinates: 34.170340 N, 131.775328 E

The dam sits on the Shimatani River, a tributary that threads through the verdant landscape of western Honshu. While official records list the height and altitude as “unknown,” the structure itself blends seamlessly into the surrounding forested slopes, creating a picturesque reservoir that mirrors the sky on clear days.

History & Significance

Although detailed historical data is scarce, 島地川ダム plays an essential role in local water management, supporting irrigation for nearby farms and contributing to flood control in the Tokuyama basin. Its construction reflects Japan’s post‑war commitment to modernizing rural infrastructure while preserving the natural environment. Today, the dam stands as a quiet testament to that balance—functional, yet unobtrusive.

Why It Matters for Travelers

• Scenic Views: The reservoir offers calm water surfaces ideal for sunrise and sunset photography.
• Cultural Insight: Visiting the dam provides a glimpse into Japan’s regional water‑resource strategies, often overlooked by mainstream tourism.
• Eco‑Friendly Spot: The surrounding forest is home to native birds and small mammals, making it a subtle wildlife‑watching location.

2. Transfer to the JR West Sanyō Main Line bound for Tokuyama.
3. Arrive at Tokuyama Station (approximately 15 minutes).

By Bus or Taxi
