Overseas Travel Of Shah Of IRAN And Emperor Of Japan!

The Tokugawa shogunate had established itself in the early 17th century. Under its rule, the shōgun governed Japan. About 180 lords, known as daimyōs, ruled autonomous realms under the shōgun, and occasionally the shōgun called upon the daimyōs for gifts but did not tax them. The shōgun controlled the daimyōs in other ways too; only the shōgun could approve daimyōs marriages, and the shōgun could divest a daimyō of his lands.
