Biography Early life Eiji Ōtsuka was born on 28 August 1958 in the city formerly known as Tanashi, Tokyo (currently Nishitōkyō, Tokyo). His father, as a repatriate from Manchuria, suffered poor living conditions in repatriate housing prior to his acceptance into university. Ōtsuka's father was a member of the former Japanese Communist Party, but he left the party due to disagreements regarding party policy. In middle school, Ōtsuka joined the dōjin circle Sakuga Group, which lead to his employment as an assistant for manga artist Tarō Minamoto in his first year at high school. The following year, Ōtsuka, with references from Minamoto, debuted as a gag manga artist. However, he soon ended his career as a manga artist during his college entrance exams after deciding that he lacked talent as a manga artist. Ōtsuka graduated the University of Tsukuba in March 1981. There, he studied Japanese folkloristics under the guidance of professor Tokuji Chiba. Ōtsuka gave up the notion of attending graduate school after he was told by instructor Miyata Noboru that his "ideas are too journalistic and not suited for academics". Career After graduation, Ōtsuka worked part-time as the editor of the magazines Ryu and Petit Apple Pie, together with manga artist Yukio Sawada. As a part-time editor, he worked with manga artist Shōtarō Ishinomori
