Minamoto no Tsunemoto Yakata
Local legends say that this was the fortified residence or castle of Minamoto no Tsunemoto (late 10th C.) which would potentially make this the oldest castle in Saitama. There's no real evidence linking it to the Heian Period, but it was certainly in use in the Sengoku Period as a fortified encampment. The castle may also have been a castle of the Mita Clan who ruled the area and had their own yakata (Fortified Manor) about 3.5km to the northwest of here. 5km kilometers across the river you'll also find Matsuyama Castle. It is thought that the site was also used by the forces of Uesugi Kenshin in the attack on Matsuyama Castle before the Siege of Odawara in 1590.
This castle is basically a simple single bailey castle with trenches around the outside and an earthen embankment on the inside. It's small, but definitely worth the 10+ min walk from the station. The site is very well preserved and well signposted.
As with many small castles from the Sengoku Period or earlier, the early history of this castle is a mystery. Google Maps and the signs on the site call it "Minamoto no Tsunemoto Yakata" so I'm using that as the main name here. It is also listed as such on most of my other materials and books. One book, however, uses Mita Castle preferring this theory over others.
