Other existing castle towers include those (of various castles such as Matsuyama-jo Castle (Bicchu Province), Matsuyama-jo Castle (Iyo Province), Hirosaki-jo Castle, and Marukame-jo Castle) where only the castle towers have been preserved as the main buildings housing the respective castle towers were removed or lost prior to the time when their preservation was decided after the Meiji Restoration.
また、明治維新以降に保存されるまでの経緯で付属する建物を撤去、または損失したことにより主に主体のみが保存されることになったもの（松山城(備中国)・松山城(伊予国)・弘前城・丸亀城など）などである。
