Japan’s Sengoku, or Civil War, Era has seen the creation of a permanent wartime economy that results in markedly increased GNP.

Daimyos encourage the development and expansion of rice farming, support flood control programs, and open new mines.

The era sees the introduction of new iron refining technology.

On the negative side, the war era sees the devolution of social and ethical mores and the erosion of loyalty, honesty and other virtues associated with Bushido, the warriors’ code of behavior.

As daimyo began to be slain by their own men, a new word comes into use: Gekokujo, meaning “one of lower class slays one of the higher”.
