Masaya Tokuhiro is a Japanese manga artist recognized for creating long-running serialized works in Weekly Shōnen Jump and other Shueisha publications. He was born in Ōtoyo, Kōchi Prefecture, on March 1, 1959. Tokuhiro first gained attention in the industry by placing as an entry in the 17th Akatsuka Awards in 1982 with his story Bijō wa Niku-Ryori ga Tokui. His first regular manga series, Shape Up Ran, was serialized in Weekly Shōnen Jump from 1983 to 1985, establishing his reputation as a creator who balanced comedic gag elements with more dramatic narrative components.

Tokuhiro is best known as the original creator of the manga Jungle King Tar-chan, also known in Japanese as Jungle no Ouja Taa-chan. The series began serialization in Weekly Shōnen Jump in 1988 and served as a parody of the classic Tarzan archetype created by Edgar Rice Burroughs. The initial run concluded in 1990 and was collected in seven tankōbon volumes. A direct continuation titled New Jungle King Tar-chan ran in the same magazine from 1990 until 1995, spanning twenty additional volumes. The complete manga series was adapted into a fifty-episode anime television production. The anime was directed by Hitoshi Nanba, produced by the studio Group TAC, and originally broadcast on TV Tokyo from October 1993 to September 1994. Beyond the anime, Tokuhiro's original concept for Jungle King Tar-chan was also adapted into at least two action video games released by Bandai in 1994 for the Game Boy and Super Famicom platforms.

Throughout his career, Tokuhiro has created numerous other manga works across different publications. While still active in Weekly Shōnen Jump, he simultaneously produced Fundoshi Police Ken-chan and Chaco-chan for Super Jump from 1986 to 1990. His later notable series include the science fiction and martial arts story Kyōshirō 2030, serialized in Super Jump from 1997 to 2004, as well as the supernatural narrative Showa Eternal Immortal Legend Vampire and its sequel Near-Future Eternal Immortal Legend Vampire. Other works include Wrestling with Momoko, Fuguman, Teishu Genki de Inu ga Ii, Kōmon-sama - Suke-san no Yūutsu, and Mokkori Hanbei.

Tokuhiro incorporates recurring thematic elements into his art and storytelling. His works frequently feature his personal interests such as firearms, bodybuilding, highly developed muscular physiques for both male and female characters, and the martial art Shorinji Kempo. The comedic elements in his narratives often involve absurdist humor and unconventional bodily gags, as seen in the unusual fighting techniques of Jungle King Tar-chan. Tokuhiro has also played a role in the development of other major manga artists. He employed a young Eiichiro Oda, the future creator of One Piece, as one of his assistants. Oda has publicly acknowledged adopting several ideas and stylistic approaches from Tokuhiro during this period.
