Satoshi Ikezawa is a Japanese manga artist and original creator, born on August 27, 1950 in Chiba Prefecture. He made his professional debut in 1969 with the comedy manga Hello Jerry, serialized in Weekly Shōnen Jump. While his early work included several humorous series such as Arashi! Sanbiki, his career became defined by a long-standing focus on motorsports.

Ikezawa is best known as the creator of Circuit no Ōkami, a seminal manga about automobile racing. The series was serialized in Weekly Shōnen Jump from December 1974 to July 1979 and compiled into 27 volumes. Its success helped popularize grand Prix racing in Japan and established the creator as a leading figure in the genre. The franchise expanded beyond the page with a live-action film adaptation released in Japan on August 6, 1977.

Following the original series, Ikezawa wrote and illustrated the sequel Circuit no Ōkami II: Modena no Tsurugi, which was published in Weekly Playboy from 1989 to 1995 and collected in 25 volumes. This sequel was adapted into an original video animation, or OVA, released on December 21, 1990. The 45 minute OVA, produced by the notable studio Gainax, follows the adventures of a former racer and motor journalist named Ken Ferrari. Ikezawa is credited as the original creator for this anime adaptation.

Another of his manga works adapted into an anime is Beat Shot!!, a sports comedy focused on golf with adult-oriented content. The original manga ran from 1985 to 1989 and spans 11 volumes. Its single episode OVA adaptation was released on May 25, 1989, produced by Gainax, with Ikezawa again serving as the original creator.

Throughout his career, Ikezawa consistently returned to themes of competitive driving and high performance vehicles. Beyond the Circuit no Ōkami franchise, his other works in this vein include Midship Jun, Highway Racer Go, Racing Kozō Arashi, Speed Connection, and Wow! F1. His artistic identity is strongly linked to these racing narratives, making him a notable figure in the development of the motorsports genre in manga. His career also included a broader range of genres, as seen in the comedy Arashi! Sanbiki and the martial arts series Kaze! Hana! Ryū!.

The industry significance of Satoshi Ikezawa rests primarily on the impact of Circuit no Ōkami. The series was highly influential in fostering a Japanese audience for Formula One and motorsports culture during the 1970s. His body of work represents a dedicated focus on automotive themes within the manga medium, leading to multiple anime adaptations and a live action film.
