During childhood, he experienced the trauma of post-World War II Japan and atomic weapons.
He drew manga since he was a child, influenced by Osamu Tezuka and Mitsuteru Yokoyama, being especially an avid reader of the latter's series Tetsujin 28-go.
In the late 1950s, Ebisu discovered the emerging gekiga genre and was immediately affected.
"My interests and my themes changed", he recalled, "I moved from giant robots to human beings and realistic stories."
Furthermore, he attributed great importance to the influence of American action films, in particular The Last Command directed by Frank Lloyd and starring John Wayne, which inspired him to invent increasingly original and intense representations in the use of works.
