Niitakayama Castle was built in 1552 by Kobayakawa Takakage. Takakage moved Numata Kobayakawa clan`s main base from Takayama Castle which located on the mountain across the numata river.[4][5]

In 1561, Takakage`s father Mōri Motonari visited the castle and spent 10days.[2] In 1596, Takakage moved to Mihara Castle, stones and materials were transferred to Mihara castle at that time.[4]

The castle was listed as one of the Continued Top 100 Japanese Castles in 2017.[6]
