Toyotomi Hideyoshi was a Sengoku period daimyo who unified Japan. He succeeded his former liege lord, Oda Nobunaga, and brought an end to the Sengoku period. The period of his rule is often called the Momoyama period, after Hideyoshi's castle. He is noted for a number of cultural legacies, including the restriction that only members of the samurai class could bear arms.
