Kajiro Tanaka, also known as Kajirou Tanaka, is a Japanese actor and voice actor born on April 5, 1972. He is recognized primarily for his supporting roles in anime and live-action television, particularly his performance in the early 2000s cyberpunk series Texhnolyze.

Tanaka's most prominent anime voice role is Kano in the 2003 cult classic Texhnolyze. In the series, Kano is a significant antagonist who serves as the inbred and solipsistic ruler of The Class, the ruling body of the underground city of Lux. Kano views Texhnolyzation, the process of replacing body parts with mechanical prosthetics, as the next stage of human evolution and uses the technology to create mindless, cyborg soldiers known as "Shapes". Although Texhnolyze features a large ensemble voice cast, Tanaka's portrayal of the detached and evolution-obsessed Kano is a key element of the show's dystopian narrative.

Outside of his voice work in anime, Tanaka has appeared in live-action tokusatsu productions. He played the role of Hiro Sakakibara's father in an episode of the long-running Super Sentai series, Samurai Sentai Shinkenger. More recently, his acting credits include a role in the 2022 Japanese television series THE 重大事件, where he played a character named Kamiya Chikara across nine episodes.
