Zen-chan Tsū-chan (lost educational anime series; 1969-1970)
Zen-chan Tsū-chan (ゼンちゃんツーちゃん) is a Japanese educational anime series produced by Jiho Eigasha. It was aired in October 20, 1969 until January 17, 1970 on Nippon TV. Each episode is 5 minutes long.
A 15-minute traffic safety film based on the anime was later released in 1971.
Little else is known about the show; it was mentioned in a newspaper listing and Masako Nozawa was credited as voicing one of the characters.
The show has never had any reruns since 1978 when it last aired on Yomiuri Television.
The PSA film seems to have resurfaced somewhere, as two people allegedly watched it on September 24, 2016.
No episodes of the actual anime series have been signaled anywhere, though.
