Tenshu

The year is 1565 and the assassination of the shogun, or military dictator, has destabilized the Ashikaga ruling family. In the ensuing power vacuum, samurai warlords, known as daimyo, battle for control and civil war rages across Japan.

To be named the next shogun you must consolidate power, construct castles called tenshu, levy taxes of koku, train and arm your samurai in order to make allies from among the five most powerful clans.
