Satoshi Yoshida is a Japanese manga artist and the original creator of several long-running series, including the works that inspired the anime Shin Shōnan Bakusōzoku Arakure Knight. Born on December 8, 1960, in Fukuoka Prefecture and raised in Fujisawa, Kanagawa Prefecture, Yoshida first aspired to become a manga artist after a prolonged hospitalization due to a skiing accident. He studied at the Tokyo Designer Gakuin College before making his professional debut in 1982. His debut work, Tenjōkai Story, was published in a special issue of Weekly Shōnen King, and he launched his first serialization, Shōnan Bakusōzoku, shortly thereafter.

Yoshida is most widely recognized for creating the Shōnan Bakusōzoku franchise. The original manga, which ran from 1982 to 1988, focused on a group of high school friends and their motorcycles, capturing the spirit of youth culture in the Shōnan area. The series became a significant commercial success, generating a social phenomenon and spawning numerous anime and live-action film adaptations. A notable example from this franchise is the anime New Shōnan Bakusōzoku: Arakure Knight, released in 1997, which was based on his manga Arakure Knight. The original Shōnan Bakusōzoku manga was also adapted into an OVA series starting in 1986, with Yoshida himself contributing to the anime production as an original character designer.

Following the success of his debut, Yoshida has maintained a prolific career, publishing works across both shōnen and seinen magazines. He is known for his long-form storytelling, often revisiting and expanding his most famous series. The Arakure Knight storyline, a successor to Shōnan Bakusōzoku, began serialization in 1995 and has continued for decades under various subtitles, such as Black Echoes - Final Chapter and Remember Tomorrow, the latter of which began serialization in 2018. His other notable manga include Chotto Yoroshiku! (1985-1987), DADA! (1989-1991), and Salaryman Hai! (2013-2016).

Yoshida has earned recognition within the broader manga and anime industry. Animation director Hayao Miyazaki has publicly stated that he is a fan of Yoshida's work, providing commentary for Yoshida's manga Birdman Rally and praising Shōnan Bakusōzoku as a masterpiece that offers a unique perspective on societal norms. Several prominent manga artists, including Kenichi Muraeda, began their careers as assistants to Yoshida. He continues to create new work, having launched a prequel series, Shōnan Bakusōzoku First Flag, in 2022, demonstrating his enduring influence as a creator of youth-oriented and motorcycle-themed manga.
