Akiyama had very pale skin and large eyes (for a person of Japanese descent in that era). He was often mistaken for a European student by many foreign instructors such as Jakob Meckel while at the Japanese Army Academy, and developed a reputation as a “ladies' man,” much to the envy of his colleagues during his stay in France, whereas he himself disliked his attractive looks. He was an impartial man who had a bowl of rice with slices of pickles for his meal. However, he spent his money on "sake" and had a reputation as a heavy drinker.
