All of Japan is controlled by the dictatorial Hideyoshi either directly or through his sworn vassals, and a new national government structure has evolved: a country unified under one daimyo alliance but still decentralized.

The basis of the power structure is again the distribution of territory.

A new unit of land measurement and assessment—the koku—is instituted.

One koku is equivalent to about one hundred and eighty liters of rice; daimyo are by definition those who hold lands capable of producing ten thousand koku or more of rice.

Hideyoshi personally controls two million of the eighteen and a half million koku total national assessment (taken in 1598).

Tokugawa Ieyasu, a powerful central Honshu daimyo (not completely under Hideyoshi's control), holds two and a half milllion million koku.
