Hitoshi Tanimura is a Japanese manga artist and original creator, born on September 13, 1953, in Fukuoka Prefecture, Japan. He began his career in the manga industry in 1972 as an assistant to fellow manga creator Jōya Kagemaru. By the late 1970s, his work began attracting attention, leading to his first major serialized series, Show Up High School, published in 1980.

Tanimura is credited as the original creator of the manga High School Agent. The series was serialized in the manga magazine Comic Burger in 1988 and later compiled into two volumes by the publisher Scholar. The story follows teenager Kanemori Kousuke, a high school student who works as a secret agent for an international spy network, using his computer skills to track criminals. The manga was adapted into a two-episode original video animation (OVA) produced by the studio J.C. Staff. The OVA was released in 1987 and directed by Jun'ichi Sakata, with Tadashi Tsukasa handling character designs.

Beyond High School Agent, Tanimura created numerous other manga series across various genres. His body of work includes Hard Boy Rudo (1984-1986), Yokosuka OP (1986-1988), and Tōryū Legend (1994-1995). He is also known for Pachipuro Tantei Nana (1994-2000), which became one of his most successful series. Several of his works have been adapted for the screen. The manga Tōryū Legend was adapted into a live-action film in 1995, and his series Immovable received an adaptation in 1996-1997. The manga Fudoh, which he wrote and illustrated beginning in 1991, was adapted into a series of live-action films released between 1996 and 1998. The Pachipuro Tantei Nana series was also adapted beginning in 1997. A recurring subject in Tanimura's extensive bibliography is pachinko, a popular Japanese gaming device, about which he has authored numerous strategy and guidebooks.
