Kiichi Okamoto was born in Sumoto on Awaji Island, Hyogo Prefecture. He and his family moved to Tokyo in 1892 for his father's promotion to the vice-president of Miyako Shimbun.
In 1906, he was apprenticed to Seiki Kuroda to study yoga at the age of 18. Among his fellow pupils was Ryusei Kishida, with whom Okamoto formed an artists' group and named it Fusain Society (Fyuzankai) to promote post-impressionism. Enthralled by Vincent van Gogh and Paul Cézanne, they held an exhibition challenging the conservative Bunten in 1912. It angered Kuroda and brought an end to their mentoring relationship, leading to the split of Fusain Society. Nevertheless, Okamoto and Kishida organized a new group together with Shohachi Kimura and Kotaro Takamura to give an exhibition of their own paintings in October 1913.
In 1914, upon his marriage, Okamoto moved next door to Kusuyama Masao, a popular theater critic and translator of Western literature. Kusuyama helped Okamoto expand his activities to include stage design, and also asked Okamoto to draw illustrations for a series of juvenile novels Mohan Katei Bunko, of which he was the editor-in-chief, in 1915.
Okamoto began drawing for Kin no Fune, a magazine of children's literature and songs, in 1919. Knowing Ujo Noguchi through his jobs, Okamoto drew illustrations for Noguchi's works.
In 1922, Okamoto was named chief illustrator for Kodomo no Kuni from its second issue. Kodomo no Kuni was sold at a half yen per copy, relatively expensive compared to rival magazines, but was enough competitive due to its high quality of the pictures.
Starting to work for Shojo Club in 1923 and for Kodomo Asahi in 1924, Okamoto became the most popular illustrator for children in Japan in the 1920s. In 1927, he participated in forming the Japan Association of Illustrators for Children with Takeo Takei, Tomoyoshi Murayama and other painters.
He had been busy with his work until just a few days before he died of typhoid fever at the age of 42 in Tokyo.
Okamoto married Kishiko in 1914 and had two sons. His elder son, Hajime, became a professional yacht photographer.
