Moonlight Mask
Whereas Super Giant (Starman) is Japan's first celluloid superhero (i.e.: he debuted in "movies" in 1957), it was Moonlight Mask (Gekko Kamen) who set the standard as Japan's first live-action TV superhero, and was a huge success with children. Television was new in Japan, so many children who did not have a TV set were gathered around to watch it at a friend's or neighbor's house. Children also bought toy capes, sunglasses, masks and pistols, and played Moonlight Mask in schoolyards and backyards (but as with every children's superhero, Japanese or American, Moonlight Mask was not without liability casualties; see Liability issues and cancellation below).
