The Fight! Iczer One original voice anime was first released in 1985. It features Cthulhu, robots and naked anime girls. A recent TV broadcast in Japan thought the best way to handle the adult scenes was with giant black bars.
Note: the bars on the side are for the correct aspect ratio.
Oh, and a notice to viewers to watch the watch the parts of these scenes that could be shown on Television Kanagawa (see below).
Surely, there’s a more artful way to edit these scenes for TV than giant black bars.
