Jun Tomizawa is a Japanese manga artist and original creator known for his work in the 1980s and 1990s. Born on April 11, 1960, in Tokyo, Japan, he began his career as an assistant to the prominent manga artist Masami Kurumada, creator of Saint Seiya.

Tomizawa’s early work as a manga author appeared in Weekly Shonen Jump. His first serialized work in the magazine was Gakuen Johobu H.I.P., which ran for 29 chapters from 1984 to 1985. This was followed by Pankra Boy, an 11-chapter serialization published in 1987. He is also noted as having worked with fellow manga artist Izumi Matsumoto during this period.

His most recognized creation is the manga Kigyou Senshi Yamazaki (Business Commando Yamazaki). The series was serialized from 1992 to 2000 and was compiled into twelve tankōbon volumes. The story follows a workaholic businessman who, after dying from overwork, is resurrected as a cyborg consultant who uses his enhanced abilities to solve corporate problems while grappling with his lost humanity.

In 1997, this manga served as the basis for the original animated video (OAV) titled Kigyō Senshi Yamazaki: Long Distance Call, for which Tomizawa is credited as the original creator. The OAV was produced by the animation studio Ripple Film and directed by Tsuneo Tominaga. The adaptation focuses on a story from the manga’s third volume, depicting the protagonist Yamazaki Takurou on an assignment to help an electronics firm develop a new product.

Tomizawa’s work is characterized by a distinctive blend of corporate culture satire and cybernetic action. Kigyou Senshi Yamazaki uses its cyborg premise to explore themes of salaryman life, sacrifice, and the dehumanizing aspects of intense workplace dedication, framing the protagonist’s efficiency as both a strength and a tragic condition.
