Ishimurajō is said to have been constructed in the Kamakura period, but the veracity of this is unclear. The ruins appear to be Sengoku period, when it is believed Ishimurajō was used as a signal tower and look-out, and as a satellite fortification of Ôkurajō.
Ishimurajō is a yamajiro (mountaintop castle) ruin on a hill surrounded by fields and orchards in Toyono Township, Nagano Municipality. The small fort site consists of kuruwa (baileys), with a central bailey with horikiri (trenches) on either side. It is a very simple structure.
