Ryūichi Yokoyama

His series Edokko Ken-chan (江戸っ子健ちゃん), created in 1936, quickly achieved great success and was the first manga to be adapted as a live-action film (1937).

In the same year, the Fuku-chan (フクちゃん) spin-off came out,[2] which became the most popular manga of its time[3] and influenced several other artists, including Osamu Tezuka.

For Hyaku Baku (百馬鹿), which came out from 1968 to 1970 in the magazine Manga Sunday, he received the 1979 prize from the Japan Cartoonists Association Award.

In 1955, Yokoyama directed the short film Onbu Obake (おんぶおばけ, Piggyback Ghost),[6] which was performed only once in front of a special audience.

With veteran animator Maeda Hajime, work became more organized, with Yokoyama's role in the productions gradually fading into the background, even though he was officially credited as director.

However, Yokoyama's commitment to animation films was already exhausted during the production of Otogi Manga Calendar and he turned away from the industry, leaving it to the emerging studios from 1963 onwards.
