Mirrorman (ミラーマン, Mirāman) is a Japanese tokusatsu science fiction television series produced by Tsuburaya Productions, the series aired on Fuji TV from December 5, 1971 to November 26, 1972, with a total of 51 episodes. This was Tsuburaya Productions' first non-Ultra superhero (even though there were concepts that were similar to Ultraman, which became Tsuburaya trademarks). Like Ultraseven, Mirrorman was more of a dark and brooding science fiction drama than most other shows of its ilk, but by Episode 26, after major changes were forced upon the series by the network (making the action lighter and the hero more like Ultraman), it became a typical action-oriented superhero adventure of its era.
