Matsuyama Castle (Gunma)




Matsuyama Castle was built by Ueda Shinzen, who was allied with the Hojo to set up a base for attacking into the Agatsuma area including Iwabitsu Castle. The castle was called Matsuyama Castle after Ueda's home castle of Matsuyama in Saitama. Takatome Castle behind it on the mountain may have been used as a fallback position if needed, but the lower elevation of Matsuyama Castle was more conducive to controlling the highway leading to Nagano.

Another recent theory states that given the shallow depth of the trenches, Matsuyama Castle was actually older than Takatome Castle. It may have been the original home of the Nagano before they built Takatome Castle, making Matsuyama Castle an extended fortification of Takatome Castle too. Regardless, the Ueda also fortified Matsuyama Castle.

Visit Notes

See Takatome Castle for more details about how to get here. It's a small castle ruin but it's a must see if you're going to visit Takatome Castle anyway. The history is somewhat conflicting, but if you visit the site it's very easy to see that even if it wasn't officially a castle before the building of Takatome Castle, there was likely some kind of fortification here at the entrance to Takatome Castle. There are no signs on the site that talk about the castle, but the book 境目の城と館(上野編) has a good map.
鷹留城へ行ったついでに松山城にも寄りましょう。遺構は少ないけれどわかりやすい構造の小規模の城跡です。ここも地図と説明板はないけれど境目の城と館(上野編) にはいい地図が載っています。
