History

Koga developed in the Muromachi period as the Koga kubō, a secondary government created by the Ashikaga shogunate to rule eastern Japan. However, the site has been inhabited since the Jomon period and was one of the largest centers for iron production in eastern Japan in the Heian period. In the Sengoku period, it developed into a castle town and became the seat of the daimyo of Koga Domain under the Edo period Tokugawa shogunate. The town of Koga was established on April 1, 1889 with the creation of the municipalities system. The modern city was founded on August 1, 1950. On September 12, 2005, Koga absorbed the towns of Sanwa and Sōwa (both from Sashima District) to create the new and expanded city of Koga. The new city hall is now located at the former town of Sōwa.
