Ichinodaira Castle (Ina)
It is thought that Ichinodairajō and Kamihiraidekojō worked as twin sites as branch fortifications of Ōjō high above. It is most likely that Kamihiraidekojō was built first with Ichinodairajō built as an extension.
Ichinodairajō is located directly opposite the site of Kamihiraidekojō. Ichinodairajō is higher situated and appears to be larger in scale. There is a wide,flat area, all covered in snow when I visited, and embankments where a forest road grants access. This entry point with an embankment is tantalising but I could not be sure of it being related to any ruins of the fort, and in fact it appears unlikely. The 'taira', or plateau, is situated beneath steep elevation. No fort should be built in such a vulnerable position, but it appears that the ridge above here was also shaped into a bailey. The natural ridge continues to climb undisturbed above these two former baileys.
