The principal officer training school for the Imperial Japanese Army was established as the Heigakkō in Kyoto in 1868. It was renamed in 1874 to the and relocated to Ichigaya, Tokyo. The second Army Academy was built by the second French Military Mission to Japan. The inauguration was in 1875. This was an important Military Academy for Japanese Army officers. It is on the same ground as the modern Japan Ministry of Defense. The second French Military Mission also helped reorganize the Imperial Japanese Army, and establish the first draft law (January 1873). Some members of the mission became some of the first western students of Japanese martial arts in history. Such as Étienne de Villaret and Joseph Kiehl were members of the dojo of Sakakibara Kenkichi and learned Jikishinkage-ryu. Captain Jules Brunet, initially a French artillery advisor of the Japanese central government, eventually took up arms alongside the Shōgun Tokugawa Yoshinobu's army against the Imperial troops during the Boshin War.
