29.6% 03/22/1986 (Sat) *6:30pm-*7:00pm Fuji TV Gegege no Kitarou (3rd Series)
There were some shows listed on here that had multiple television series, so I have indicated which series the list is referring to. For example, Gegege no Kitarou has had five different television series produced (excluding Hakaba Kitarou). The one that aired at the date indicated is the 3rd series, which I noted in parenthesis. I did the same with the other shows like Lupin The Third.
The only show I didn't do this with was Dokonjo Gaeru. This is because its airdate does not match either of the two television series. However, I assume that it's the first series on reruns, because the second series did not premiere until 1981.
If I made any mistake, mention it and I'll make the correction.
