is a 1958 tokusatsu superhero television series. Created by veteran writer Masaru Igami and produced by Nippon Gendai and Senkosha, the series aired on NTV from November 4, 1958 to October 6 1959, with a total of 49 episodes (divided into several segments). It was created to capitalize on the success of the Super Giant serials. In fact, the title hero (whose alter-ego was Waku-san, played by Toshio Mimura) bore a strong resemblance to Super Giant. For release in America, these two movies were compiled into a TV movie titled Prince of Space.
