Katsuyama Palace is classified as a mountain castle, and is located in Yamaguchi Prefecture. During the pre-modern age, it found itself within the borders of Nagato Province. It is associated with the Mōri clan. Dates in use: 1863 - 1871.

My visit here was very enjoyable with more that few surprises. First off, there was the sensationally-maintained grounds. Next, there were the similarities and differences when compared with a typical (1600's) castles. The final surprise was that it seemed the purpose of the large walls was to aide in terracing more-so than just as a barrier.
