History

The area of present-day Inawashiro was part of ancient Mutsu Province and the location of Inawashiro Castle since the Kamakura period. It was the site of the Battle of Suriagehara during the Sengoku period. The area formed part of the holdings of Aizu Domain during the Edo period. During the Boshin War, the Battle of Bonari Pass took place near Inawashiro. After the Meiji Restoration, the area was organized as part of Yama District, Fukushima Prefecture. The town of Inawashiro was founded with the establishment of the modern municipalities system on April 1, 1898. The town borders expanded considerably in 1955 through a merger with the villages of Iwase, Iwaho, Azauma, Nagase, Tsukinowa, Chisato, and Okinajima.
