History

Hear the voices of the ancients who openedup and made Shonai prosper a long time ago.

Yamagata Prefecture is divided into four districts, and one of them is the Shonai district. It lies in the western part of Yamagata Prefecture, facing the Japan Sea, and is now comprised of two cities and three towns. It is said that in medieval times, there were three large shoen (manors) in this district and the most prosperous was Oizumi (the current Tsuruoka City and its environs). Shonai originally means the inside of shoen, and it has come to mean the whole Shonai district in modern times. The country of Dewa was formed in Shonai in the year 712, which led the district to flourish.
