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.

With the depletion of the mineral deposits at the Kosaka Mine from the 1990s, the economy of Kosaka is now largely based on agriculture, forestry and seasonal tourism. 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.

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.
