Tokugawa Ieyasu was the founder and first shōgun of the Tokugawa shogunate of Japan, which effectively ruled Japan from the Battle of Sekigahara in 1600 until the Meiji Restoration in 1868. Ieyasu seized power in 1600, received appointment as shōgun in 1603, and abdicated from office in 1605, but remained in power until his death in 1616. His given name is sometimes spelled Iyeyasu, according to the historical pronunciation of the kana character he. Ieyasu was posthumously enshrined at Nikkō Tōshō-gū with the name Tōshō Daigongen (東照大権現). He was one of the three unifiers of Japan, along with his former lord Nobunaga and Toyotomi Hideyoshi.
