History

The area of present-day Kosaka was part of ancient Mutsu Province and was ruled by the Nambu clan of Morioka Domain during the Edo period. The “Kosaka-kaido” highway connecting Morioka Domain with Hirosaki Domain passed through Kosaka. Under the Nambu, major deposits of gold and silver were mined by the Fujita-gumi, the predecessor to modern Dowa Holdings for the Nambu clan at the Kosaka mine. After the start of the Meiji period, the area became briefly part of Rikuchū Province before being transferred to Akita Prefecture in 1871. It was organized as part of Kazuno District, Akita Prefecture in 1878. The village of Kosaka was created with the establishment of the modern municipalities system on April 1, 1889. It was raised to town status on May 12, 1914.

Economy

The town prospered greatly as a mining center for gold, silver, copper and zinc in the Meiji period, and many modern buildings were built, including the Kosaka mining office. After the Second World War, mining resources were depleted and the town declined. In recent years, there have been efforts to find ways to create a town that makes use of the modern architecture of the Meiji period and the tourism resources of Lake Towada. In addition to this, Dowa Holdings, the owner of the Kosaka Mine, is active in the metal recycling industry. In terms of light manufacturing, the Towada Audio Corporation, a manufacturer of shortwave radio sets, TV tuners and AC adapters in the Sony group, is based in Kosaka.

Education

Kosaka has one public elementary school and one public middle school operated by the town government and one public high school operated by the Akita Prefectural Board of Education.

The Kosaka Smelting & Refining Kosaka Line provided passenger services until 1994. At present, the town is not served by any passenger railway line.
