All castles, Japanese or otherwise, were built with one focus in mind: protection. While it is true that some of the later-built castles in Japan were very ornate and decorative, they still had the basic structures necessary to put up a basic defense. So what happened when ambitious armies tried to break those defenses? That is what our simulation is designed to explore.

This simulation does not go into the minute details of castle defenses, but it does give a good overview. There are walls, moats, yagura, gates, and of course tenshu. Each castle map in the simulation was carefully designed using maps of the actual castles, so the organization of each of the castles' layout remains the same. There are also a variety of troops to command and to conquer. In order to make this simulation enjoyable as well as educational, several liberties were taken with historical accuracy. These are all detailed on the notes page.
