Anoriginal net animation (ONA), known in Japan asweb anime (ウェブアニメ,webu anime), is ananime that is directly released onto theInternet.[1][2] ONAs may also have been aired on television if they were first directly released on the Internet. The name mirrorsoriginal video animation, a term that has been used in the anime industry forstraight-to-video animation since the early 1980s.
A growing number of trailers and preview episodes of new anime have been released as ONA. For example, the anime movie ofMegumi can be considered an ONA. ONAs have the tendency to be shorter than traditional anime titles, sometimes running only a few minutes.[3] There are many examples of an original net animation, such asHetalia: Axis Powers, which only last a few minutes per episode. But while that was true for the beginning of the 2010s, this began to change in the second half of the decade as full series began to be licensed exclusively for streaming services likeNetflix,Amazon Prime Video, andDisney+.
Most animation in Japan is made for television or for other audio-visual formats, which include ONAs that can be viewed on television, mobile devices or computers.[4]
