## Geography

Ōgata is located northwestern Akita Prefecture, and is a polder consisting entirely of land reclaimed from the former Hachirōgata Lagoon. The outer periphery of the village, which forms an almost elliptical shape, is formed by the remnant waters of Hachirōgata Lagoon, and this water area forms the boundary with the surrounding municipalities. Ogata and surrounding municipalities do not touch directly, but are connected only by seven bridges. To the south of the village is the Hachirōgata Regulating Reservoir (also known as Lake Hachiro, or sometimes called still called "Hachirōgata" ). The eastern drainage canal forms the perimeter of the village and extends northwards, joining the western drainage canal due north. The western aqueduct extends from north to southwest and connects with the Hachirōgata Regulating Reservoir. The former Hachirōgata Lagoon remains in the form of a regulating pond in the south. Apart from this, irrigation canals and drainage canals have been developed inside the village. In Ogata, where most of the land is at or below, sea level, an artificial hill was constructed as a symbol of the village in the 1990s. "Ogata Fuji" has a relative height of 3.776 meters. Most of the village area of Ogata is farmland, with the urban center in the west central part of the village area.

Over the next twenty years, with the help of Dutch engineers, around seventeen thousand hectares of new farmland were created. Ōgata village was founded on this newly reclaimed land on October 1, 1964. Between 1967 and 1974 about 580 settlers took up residence in the new village of Ōgata, bringing their families with them.
