Ogiwara Castle (Azumi)
In 1552 Takeda Shingen attacked Kariyaharajō. One account goes that in the attack Ogiwara Yaemon took the head of Ôta Suketada, earning valour - though other accounts dispute this. Ogiwara Yaemon would later establish himself at Ogiwarajō. There is also a theory that Ogiwarajō was the birth place of the Nishina Clan.
To Ogiwarajō ruins I took a forest trail and hopped off when I came near the ridge which led to the castle ruin. I identified at least one bailey and trench work, particularly to the rear. The ruin is covered in bamboo. There was another wide trail here. It looked to me that some earthwork ruins may have been cut through to build the dirt track. I have since found confirmation that the track went clear through the whole site! The track demolished the northern perimeter of the fort, filling trenches, flattening embankments, and cutting into the baileys. This is unfortunate.
North of Ogiwarajō there is a speculative site called 'Pond Door Castle'. The Ogiwara Clan residence was located on the slopes to the north of Ogiwarajō.
