Tokugawa Mitsukuni
Kuniyuki Tokugawa inherited the title of "shishaku" (侯爵, marquis) under the "kazoku" peerage system on the death of his father, Tokugawa Atsuyoshi in 1898. A scholar, he turned his attention in 1906 to the completion of the "Dai Nihonshi", a comprehensive history of Japan begun by his ancestor, Tokugawa Mitsukuni in the 17th century. However, in 1910, he was accepted into the 22nd class of the Imperial Japanese Army Academy, and was commissioned as Second lieutenant in the Imperial Japanese Army. He resigned his commission in 1914 citing health reasons, and went into the reserves in 1915.
