Conquest of Japan is a strategy title in which you must conquer your opponents cities on the Island of Honshu in 16th century Japan. The ten cities must be occupied to win, you do this by forming armies to defend your five cities and attack those of your opponent. When a city is taken, any mobile army that came from that city is automatically disbanded. In this way, potentially overwhelming forces can be routed by conquering their cities -- but only if you can conquer the city before its army reaches its target. Depending on how the cities are located at the start of the game, you may find this to be a key part of your campaign strategy. When armies battle, the game switches from the strategic map, to a tactical one. Formations, unit orders, and moral are factors in the tactical battles.
