Yokoo Nobumitsu died at the Battle of Uedahara (1548), despite it being a great victory for the Murakami. His son was too young to become the new lord so the lands went to the Sanada. It is likely the Sanada manned it as one of the fortifications in their rich network around this plain. Even though each castle is not necessarily large nor strong the advanced network of castles around this area creates a formidable defense. The temple (Shinkoji) behind the castle was erected by Sanada Masayuki to his brother who perished at the Battle of Nagashino.
The site is not well signposted and it took some effort to find where the castle begins and ends. Basically from the Kuromon Gate, the ridge extending to the right (east) was the castle. You can make out some baileys that created the castle. If I were to go again, I would start from here and try to find the trail to Nagao Castle which should be around Shinkoji Temple and take it to Nagao Castle and down to Obiki Castle on the other side. There are many Sanada related castles nearby. It would take several days to see them all.
