Hachirōgata


Hachirōgata is a lake in Akita Prefecture in northern Japan. Its formal name is Lake Hachirō, but it is also called Hachirōgata Regulating Pond. At 4 meters below sea level, Hachirōgata is the lowest natural point in Japan.
Hachirōgata was the second-largest lake in Japan after Lake Biwa. Extensive reclamation began in 1957 for crop production, and Ōgata village was established on the reclaimed land on October 1, 1964. The remaining lake has an area of .
Some regard the reclamation as a mistake, since Japan began to be bothered with surplus rice soon after the completion of the reclamation. Others lament the loss of the wetlands.
Fishery of shijimi shells was a thriving industry, but it decreased as the lake became less brackish. In the winter, people fish wakasagi by hollowing out the frozen surface. Today, black bass fishing attracts tourists even outside the prefecture, though some suspect that indigenous species are threatened by the invasion of the extraneous fish.

Legend

According to a legend, a man called Hachirō was transformed into a dragon and chose the lake for his home after wandering a long time. Thus, the lake was named Hachirō-gata. Later, he was attracted to a woman who owned Lake Tazawa, another lake in Akita Prefecture, and moved to be with her. After that, Hachirōgata became increasingly shallower.
