Shin-Ei Animation

Shin-Ei Animation Co., Ltd. (Japanese: シンエイ動画株式会社, Hepburn: Shīn'eī Dōga Kabushiki-gaisha) is a Japanese animation studio owned by TV Asahi and founded in Tokyo in 1965 as A Production by Daikichirō Kusube, who was previously an animator for Toei Animation.

Shin-Ei Animation's history begins in December 1965 as A Production (Aプロダクション, Ei Purodakshon) by Daikichirō Kusube who was then a former animator at Toei Animation.

Disgruntled by the rigid hierarchy prevalent in Toei Animation he, and a couple of his colleagues, formed A Production, and immediately got into a partnership with the newly-formed Tokyo Movie, under the condition that Kusube would remain independent.

For ten years, A Production served as Tokyo Movie's primary subcontractor for animation as well as co-production.

In 1976, after Tokyo Movie founded Telecom Animation Film, they offered Kusube to lead the division. However, knowing that he would lose his independence, he refused, cut all ties with Tokyo Movie and restructured his company to Shin-Ei Animation (シンエイ動画, Shin-ei Douga).

Shin-Ei Animation is best known as the animation studio behind two anime series, Doraemon and Crayon Shin-chan, which have aired on TV Asahi since 1979 and 1992 respectively; Shin-Ei Animation has since produced television series and films of the two anime series.

In 2010, TV Asahi had acquired the animation studio.

In April 2017, SynergySP became a subsidiary of the company.
