Yamagata Aritomo - Military Career

Military Career

As War Minister, Yamagata pushed through the foundation of the Imperial Japanese Army General Staff, which was the main source of Yamagata's political power and that of other military officers through the end of World War I. He was Commander of the General Staff in 1874–76, 1878–82, and 1884–85.

Yamagata in 1877 led the newly modernized Imperial Army against the Satsuma Rebellion led by his former comrade in revolution, Saigō Takamori of Satsuma. At the end of the war, when Saigo's severed head was brought to Yamagata, he ordered it washed, and held the head in his arms as he pronounced a meditation on the fallen hero.

He also prompted Emperor Meiji to write the Imperial Rescript to Soldiers and Sailors, in 1882. This document was considered the moral core of the Japanese army and naval forces until their dissolution in 1945.

Yamagata was awarded the rank of field marshal in 1898. He showed his leadership on military issues as acting War Minister and Commanding General during the First Sino-Japanese War; as the Commanding General of the Japanese First Army during the Russo-Japanese War; and as the Chief of the General Staff Office in Tokyo.

He is considered political and military ideological ancestor of the Hokushin-ron as he traced the first lines of a national defensive strategy against Russia after Russo-Japanese War.
