Built to regulate water flow and support local irrigation, 四時ダム is not a massive concrete behemoth but a functional structure that harmonizes with its surroundings. While the exact height and altitude remain undocumented publicly, the dam’s modest scale makes it accessible for casual visitors—no special permits or guided tours are required.
