Negoya Castle




In 1568, Takeda Shingen's alliance with the Hojo fell apart when he attacked the Imagawa. Takeda built Negoya Castle in between Yamana Castle and Terao Chausuyama Castle to fortify his border with the Hojo and help prevent any unrest in the Kozuke (Gunma) region. It may have worked. There is no evidence of any attacks on this area by the Hojo. The castle was likely abandoned when the Takeda withdrew from the the region.

Visit Notes

The second castle along the hike from Yamana Castle to Terao Naka Castle was Negoya Castle and it was definitely the highlight of the day. For such a short lived castle it is surprisingly complex and well developed.

Negoya Castle is along the same ridge from Yamana Castle (about 20 mins hike along the Takasaki Nature Trail). It's a fairly complex and well fortified castle for such a border castle. The main parts of the castle are well signposted, which I've tried to capture in some of the photos, but for the adventurous ones you can plow on through some high grasses or hike down a couple of the bigger tatebori to find more trenches.

The original name of the castle is unknown. The name Negoya Castle comes from the town name, but Negoya is not actually unique to this area. It is an old name used for the area around the foot of any mountaintop castle. It is where the guards and soldiers stationed at the castle lived (slept; thus neru > ne) when they were not on duty at the castle. You often see "negoya" as a place name near mountaintop castles. In this case, it was likely that the town was the negoya for Yamana Castle which existed first.
