The exact date of the castle's foundation is unknown but built in the Muromachi period. In 1543, Uesugi Kenshin left Kasugayama Castle and entered the castle as a joint commander by Nagao Harukage`s order.[4]

In 1544, Kenshin made his first battle against local lords opposed to the Nagao clan in the castle and broke the siege.[5]

In 1548, Kenshin returned to Kasugayama Castle as a feudal load of the Nagao clan.[6] The castle is now only ruins, with some earthenwalls, well and moats.[4] Its ruins have been protected as a Prefectural Historic Site.[4]
