Looking up some info on Wiki I find out that Spectreman originally aired first in Japan in 1971. Yes, that's 40 yrs ago. Also surprising, Tokyo at the time was considered one of the most polluted cities in the world and this sci-fi TV show may have been inspired by that as it dealt with 'saving the world' themes. Later on. the show aired in the Chicago area in the later 70's on UHF. I believe it was channel 44. All I remember is that it was one crazy show with a very catchy theme song.
I think Japan now needs Spectreman
