It has played an important role as an intermediate base on the Sanada road that connects Ueda Castle and Numata Castle. It is unknown who built the castle and when it was built, but it is said that Saitō Clan became the lord of the castle from 1521-28 and ruled the entire Agatsuma District. Takeda Shingen, who invaded there, ordered Sanada Yukitaka to attack Iwabitsu Castle in 1563, but failed twice due to the extremely steep terrain and the reinforcements sent by Uesugi Kenshin. Yukitaka devised a plan and caused him to fall in 1565 due to his strong strategy and surprise attack.
Even in the Warring States period, inferior to the Oda army's offensive Takeda Katsuyori wants to abandon his hometown of Shinpu Castle and head for Iwabitsu Castle, which is recommended by Sanada Masayuki, the son of Sanada Yukitaka. However, due to the suggestions of Oyamada Nobushige and the eruption of Mt. Asama, Katsuyori changed his policy and headed for Oyamada's castle, Iwadono Castle. However, at the last minute, Oyamada betrayed, and based on this,Takeda Clan followed the path of destruction.
