1560 – 1615
During Japan’s long age of provincial warfare, Oda Nobunaga, Toyotomi Hideyoshi, and Tokugawa Ieyasu successively consolidated power. Firearms contributed to Nobunaga’s victories, though the familiar story of perfectly staged rotating volleys at Nagashino is debated. Hideyoshi unified most of Japan and invaded Korea; Ieyasu prevailed at Sekigahara and destroyed the Toyotomi regime at Osaka, establishing a shogunate that lasted until 1867.
