Tetsu Kariya is the professional pen name of Tetsuya Totsuka, a Japanese manga writer and essayist born on October 6, 1941, in Beijing, China, who relocated to Japan after the war. He grew up in Tokyo’s Denenchofu district and, despite an early ambition to become a doctor, pursued a different path after finding the atmosphere of a university hospital disheartening. After graduating from Tokyo Metropolitan Koyamadai High School, he studied quantum mechanics at the University of Tokyo’s College of Arts and Sciences. Following university, he joined the major advertising agency Dentsu, where he worked as a copywriter for three years and nine months, during which time he began his career as a manga writer. He left the company in 1974 to work full-time as a freelance creator.

Kariya began his writing career in the early 1970s, initially focusing on gekiga, a style of dramatic manga for adult audiences. His first series, Hitoribocchi no Rin, was published under the pseudonym Shinya Ageta in 1972 with art by Ryoichi Ikegami. This collaboration continued with several successful works that established his reputation for crafting masculine, anti-authoritarian narratives filled with violent struggles for power. Among these were the series Otoko-gumi (1974-1979) and Otoko Ozora (1980-1982), both drawn by Ikegami, which depicted young men confronting corrupt systems.

The 1975 manga Ginga Senshi Apollon (Galaxy Warrior Apollo), illustrated by Shigeru Tsuchiyama and Ryu Kaido, is a significant work in Kariya’s career as it served as the basis for the anime series UFO Senshi Daiapolon (UFO Warrior Great Apollo), which aired from 1976 to 1977. This original concept was later adapted for a second series, UFO Senshi Daiapolon II. In 1979, he also created the original concept for the tokusatsu (live-action special effects) series Megaloman, further demonstrating his versatility in the science fiction and action genres. His other notable works from this period include Yabou no Okoku (The Kingdom of Ambition), a picaresque story about power and violence that has maintained a cult following.

Kariya is best known as the original creator of the immensely popular and long-running manga Oishinbo, which began serialization in Shogakukan’s Big Comic Spirits magazine in 1983. The series, illustrated by Akira Hanasaki, follows journalist Shiro Yamaoka as he travels across Japan to create the “ultimate menu” for his newspaper’s 100th anniversary. It became a defining work of the 1980s economic bubble era, with each of its 111 volumes reportedly selling over a million copies, achieving total sales exceeding 135 million. The story’s focus on cuisine was a turning point for Kariya, who had previously been known for violent dramas; he was inspired to write about food in part due to his own reputation as an opinionated gourmet. The manga’s success led to numerous adaptations, including an anime television series, the animated films Oishinbo: Kyūkyoku Tai Shikō, Chōju Ryōri Taiketsu!! and Oishinbo: Nichibei Kome Sensō, as well as live-action dramas and video games. In recognition of its impact, Oishinbo received the 32nd Shogakukan Manga Award in 1987.

Kariya’s work is characterized by a strong authorial voice that blends entertainment with social criticism. Oishinbo frequently delves into topics such as food safety, agricultural policy, and cultural identity, often taking critical stances against major corporations and government regulations. This willingness to address controversial subjects culminated in a notable real-world controversy in 2014. Following a storyline where the protagonist experienced radiation sickness symptoms after visiting the Fukushima Daiichi nuclear disaster site, Kariya and his publisher faced severe backlash, including accusations of defamation from government officials. The series went on an indefinite hiatus and has not resumed, despite Kariya asserting the story was based on his own experiences. This episode highlighted his commitment to using manga as a platform for political and social commentary, a theme that had appeared throughout his career.

Since 1988, Kariya has resided in Sydney, Australia, having moved his family there to provide his children with an education outside of Japan’s competitive system. He continues to write from Australia, sending scripts to his illustrators in Japan. Through his extensive body of work, from hard-boiled action dramas to a beloved culinary epic that became a cultural institution, Tetsu Kariya has established himself as a significant and influential figure in the world of manga as an original creator.
