[1] During the Second World War, three films about Fuku-chan were made for propaganda purposes and in 1982 they were adapted into an anime television series.
[2] The series' protagonist is the five-year-old street boy Fukuo “Fuku-chan” Fuchida, who mostly plays pranks on the people around him.
[3] Recurring characters include Fuku-chan's friend Kumi, playmate Namiko and her younger brother Kiyo, the cheeky twins Doshako and Garako, and Ganchan, who always annoys the other children at preschool.
The one-reel short film Uwanosora Hakase was made from a script by Yokoyama and directed by Maeda Hajime with a team of 18 over a period of eight months.
A multiplan camera was constructed for production, but could only be used to a limited extent due to the general lack of material and employees.
The screenplays were written by Masaki Tsuji, Toshiyuki Kashiwakura, Noboru Shiroyama and Hiroko Naka.
