This dam is located near Irago, famous for Toson Shimazaki's "Palm Fruit," and is the final reservoir for the Toyokawa water supply. The Toyokawa Irrigation Project was initiated to alleviate the chronic shortage of water in the Higashimikawa region. Although the dam is not very large in scale, it plays an important role in alleviating water shortages in the Higashimikawa region.

Other facilities/observations
I am always puzzled by the name of this dam. Is it "Hattachi" or "Hatsutachi"...? Even when I look around at various websites related to the Hatsutachi Dam, there are descriptions of both. Even on what could be called official websites, such as the Atsumi Town website and the Toyokawa water supply website, both descriptions are given. I am waiting for someone to give me correct information.
