Which emperor reunified Japan?

The three daimyo who unified Japan were Oda Nobunaga, Hideyoshi, and Tokugawa Ieyasu. The unification of Japan at the turn of the seventeenth century was a crucial event. It brought an end to a hundred years of warfare and to the constant military struggles among the feudal lords or daimyo.

The reunification of Japan is accomplished by three strong daimyo who succeed each other: Oda Nobunaga (1543-1582), Toyotomi Hideyoshi (1536-1598), and finally Tokugawa Ieyasu (1542-1616) who establishes the Tokugawa Shogunate, that governs for more than 250 years, following the Battle of Sekigahara in 1600.
