2. About 打上ダム
Description & History
Uchiage Dam (打上ダム) is situated at latitude 33.507656 and longitude 129.902254, just a few kilometers east of Karatsu city centre. The dam was constructed as part of a regional water‑management project, helping to regulate river flow, support irrigation, and maintain a reliable water supply for surrounding communities. While official records do not disclose its exact height or reservoir capacity, the structure reflects the typical concrete gravity design common to many mid‑20th‑century Japanese dams.
The name “打上” (Uchiage) translates loosely to “launch” or “shoot up,” a nod to the way water is released from the spillway in a controlled, upward spray—an image that has inspired local folklore and occasional festivals celebrating water’s life‑giving force.
Significance
Although modest in size, 打上ダム plays an essential role in Saga’s agricultural landscape. The reservoir supplies irrigation water to nearby rice paddies and vegetable farms, sustaining the region’s famed produce. Moreover, the dam’s calm lake has become a favored spot for birdwatching, especially during migration seasons when waterfowl pause to rest.
From a cultural perspective, the dam sits within a short drive of Karatsu’s historic sites, making it an ideal stop for travelers who want to blend nature, engineering, and heritage in a single day.
