Takasaki Castle is classified as a flatland castle, and is located in Gunma Prefecture. During the pre-modern age, it found itself within the borders of Kōzuke Province. It is associated with the Ii, Ōkōchi clans. Dates in use: 1597 - 1871.

Takasaki castle was built over the top of an older castle by the name of Wada castle. That castle was built in the 1400's but was abandoned with the defeat of the Hōjō clan in 1590. Takasaki was built up from 1598 by a vassal of the Tokugawa clan & led a pretty uneventful life. A three-story turret served as its central tower & was still standing in the late 1800's.

Nowadays, very little remains as most of the castle grounds have been reclaimed. The only exception being a small section of the San-no-maru & moat. It is there that the Inui turret & the Higashi gate have been relocated.
