Several pioneers in 1917
Shimokawa Ōten, Kitayama Seitarō and Kōuchi Jun’ichi released works in 1917. NFAJ identifies Kōuchi’s Namakura Gatana as the oldest surviving Japanese animated film. Its online collection of 64 films from 1917–1942 offers evidence of early production, not a count of everything made in those years.
Wartime commissions
Military propaganda commissions affected production. Momotarō no Umiwashi, released in 1943, marked a medium-length development; Momotarō: Umi no Shinpei followed as a feature in 1945. Animation served education and propaganda as well as entertainment. Expanding technical scale does not itself establish progress in the purposes it served.
Reorganization and the colour feature
Postwar groups and companies repeatedly reorganized. Toei acquired Nichidō Eiga in 1956 and released Hakujaden in 1958, a major colour-feature milestone. Yokoyama Ryūichi’s Otogi Production followed a different, smaller-scale route. No one studio supplies the entire industry’s history.
A weekly television series in 1963
Mushi Production’s Astro Boy began on January 1, 1963: 24-minute episodes in a run of 193. Regular television schedules supported series production. Features continued, while original video animation later added another route. Toei’s 1986 Shōnan Bakusōzoku is one company example, not the first OVA in Japan. By the late 1970s, younger fan communities and animation magazines also helped popularize the term anime. OVA identifies original animation initially released for home-video media, distinct from a cinema or television premiere followed by video. Dallos, released in 1983, is an early example; later streaming or broadcast does not change that initial release route.
Magic and friendships for a different television audience
Sally the Witch began in 1966 and ran until 1968. Its young princess comes from a magical kingdom to live among human friends. Toei describes the series as animation for girls, combining fantasy with humour and sentiment. Magical adventures and everyday friendships gave this television series a distinct audience and story world.
A gradual change in tools and circulation
Toei’s chronology records completion of its CATAS image-production software in 1991, digital systems in 1997 and networked production and digital drawing in 2000. Overseas sales, subcontracting and later online distribution broadened circulation. Adoption differed by company and task; the industry did not become digital everywhere in one year. Production tools and distribution are separate questions. Cinema, television, home media and online delivery can coexist, and one work can circulate through different routes by territory. Wider online access does not mean every work is exclusively commissioned by a platform. A signed June 2026 Finance commentary describes a change in financing as well: alongside television sponsorship, publishers, manufacturers and other participants can invest through a production committee and share rights and returns. This connects animation with publishing, merchandise and distribution. It is the writers’ industry analysis, rather than a rule governing every project.
