Mighty Jack is a tokusatsu science fiction/espionage/action TV series. Created by Japanese effects wizard Eiji Tsuburaya, the show was produced by Tsuburaya Productions and was broadcast on Fuji TV from April 6, 1968 to June 29, 1968, with a total of 13 one-hour episodes. The music for the episodes was done by Isao Tomita and Kunio Miyauchi. Reportedly, Eiji Tsuburaya considered this series his masterwork because the focus was on the people, rather than on the vehicles and special effects.
