Born on February 6, 1950 in Urahoro, Hokkaidō, Japan.
He started drawing Yonkoma manga at the age of 16 and published his first professional work called Ringside Crazy (リングサイド) in December 1969.

He is most well known for his science fiction lolicon-themed works appearing in magazines such as Weekly Shōnen Champion, as well as comedy series such as Nanako SOS and Little Pollon (which both became anime television series in the early 1980s).

Beginning in 1978, his works began appearing almost exclusively in smaller niche magazines such as Bessatsu Kisōten, including works like Fujōri Nikki. In 1979, Azuma launched his lolicon doujin magazine Cybele, the first manga of its kind in Japan. He has since been called the "father of lolicon".

He named his first mentor ITAI Rentaro, TEZUKA Osamu, ISHIMORI Shotaro and the author TSUTSUI Yasutaka as the people, who had the most impact on his works.

He passed away on October 13th, 2019, at the age of 69 due to esophageal cancer.

MITAKA Kouichi worked as his assistant. Was friends with WADA Shinji.
