Surrounding municipalities[edit]


During the Edo period, the area of present-day Annaka was the center of the Annaka Domain, a feudal domain held by the Itakura clan under the Tokugawa shogunate in Kōzuke Province. The area also prospered from its location on the Nakasendō highway connecting Edo with Kyoto. Post stations located within the borders of modern Annaka were: Itahana-shuku, Annaka-shuku, Matsuida-shuku and Sakamoto-shuku.

Annaka Town was created within Usui District, Gunma Prefecture on April 1, 1889 with the creation of the municipalities system after the Meiji Restoration. On March 1, 1955, Annaka merged with neighboring Haraichi, Isobe, and Itahana towns, and Higashiyokono, Iwanoya, Akima, and Gokan villages. It was raised to city status on November 1, 1958. On March 18, 2006, the town of Matsuida, merged with Annaka. Usui District was dissolved as a result of this merger.


Annaka is a regional commercial center and transportation hub. Toho Zinc operates a large plant in the city, as does Shin-Etsu Chemical.


There are three high schools, five middle schools, and fourteen elementary schools in Annaka.
