Yamagata Aritomo
Ōmura's ideas for modernizing Japan's military were largely implemented after his death by his followers such as Yamagata Aritomo, Kido Takayoshi, and Yamada Akiyoshi. Yamada Akiyoshi was the strongest leader out of the four and was mainly responsibly for establishing Japan's modern military using Ōmura's ideas. Yamada promoted Ōmura's ideas by establishing new military academies that taught Ōmura's ways. Yamagata Aritomo and Saigō Tsugumichi also had Ōmura's ideas in mind when passing legislation imposing universal military conscription in 1873.
