Himeji serves

Himeji serves as an excellent example of the prototypical Japanese castle, containing many of the defensive and architectural features most associated with Japanese castles. The tall stone foundations, whitewashed walls, and layout of the buildings within the complex are standard elements of any Japanese castle, and the site also features many other examples of typical castle design, including gun emplacements and stone-dropping holes.

One of Himeji's most important defensive elements, and perhaps its most famous, is the confusing maze of paths leading to the main keep. The gates, baileys, and outer walls of the complex are organized so as to cause an approaching force to travel in a spiral pattern around the castle on their way into the keep, facing many dead ends. This allowed the intruders to be watched and fired upon from the keep during their entire approach. However, Himeji was never attacked in this manner, and so the system remains untested.
