This modest yet captivating dam is an ideal stop for anyone traveling the Kyushu region who craves a slice of authentic Japanese countryside.

About 路木ダム

• Location: Ushibuka, Kumamoto, Japan
• Coordinates: 32.282016° N, 130.087075° E

Roki Dam was constructed as part of Kumamoto’s water‑resource management system, supporting irrigation, flood control, and local water supply. While its exact engineering specifications remain modest, the dam’s true charm lies in its natural setting. Surrounded by verdant forests and gently sloping terrain, the reservoir reflects the sky in a mirror‑like surface, creating ever‑changing patterns of light and shadow that captivate photographers year‑round.

The dam is referenced on Japanese Wikipedia (see the original article: https://ja.wikipedia.org/wiki/%E8%B7%AF%E6%9C%A8%E3%83%80%E3%83%A0) and is increasingly mentioned in travel guides as a “secret spot” for those seeking authentic Kumamoto experiences. Its relative obscurity makes it a perfect destination for mindful travelers who value serenity over crowds.

How to Get There

From Kumamoto City

1. By Car – The most convenient way to reach Roki Dam is to rent a car and drive north along Route 57. The journey takes roughly 1 hour 15 minutes (≈ 55 km). Follow the signs for Ushibuka and look for the small “路木ダム” sign near the reservoir’s parking lot.
2. By Train + Bus – Take the JR Kagoshima Main Line to Ushibuka Station (≈ 45 min). From there, board the local Kumamoto Bus (Route A12) toward the “Roki Dam” stop. The bus ride is about 30 minutes, and the stop is a short walk from the dam’s entrance.

From Fukuoka (or other Kyushu hubs)

• Shinkansen to Kumamoto → Transfer to the JR Kagoshima Main Line → Ushibuka Station → Bus as described above.
