木戶孝允
Many of those who had significant roles in the Meiji Restoration, or their heirs, were ennobled. Ito Hirobumi and Yamagata Aritomo were ennobled as counts in 1884, promoted to marquesses in 1895 and finally became princes in 1907. The heirs of Okubo Toshimichi and Kido Takayoshi, two of the three great nobles of the Meiji Restoration, were ennobled as marquesses in 1884, followed by the heirs of samurai general-politician Saigō Takamori in 1902.
