Takeshi Kimura (February 4, 1912 – January 1988) was a Japanese screenwriter who wrote many films for Toho studios. Kimura scripted several films for director Ishirō Honda, including Rodan, The Mysterians, Matango, Frankenstein Conquers the World, War of the Gargantuas, King Kong Escapes, Destroy All Monsters, and Godzilla vs. Hedorah. He was a member of the Japanese Communist Party whose screenplays often included political themes. His scripts are frequently contrasted with those written by Shinichi Sekizawa, whose scripts for kaiju films typically had a more lightweight, "fun" tone.
Kimura considered the screenplay for Ishirō Honda's Matango to be his best work, and he considered all of his scripts from Frankenstein Conquers the World onward to be merely work for hire. To express this dismissive view of his later work, he started writing under the pseudonym "Kaoru Mabuchi." He chose the name "Kaoru" to project an image of anonymity because it can be either a male or female name.
Kimura was known for having a dark and gloomy personality, and he was reportedly never very close to any of his fellow Toho employees. He died from a throat obstruction in his Tokyo apartment in 1988.
