->''"Domo Arigato, Mr. Roboto!"''
-->-- '''Music/{{Styx}}''', "[[Music/KilroyWasHere Mr. Roboto]]"

A cultural movement in American pop-culture which had precursors in TheSixties, but began fully in TheEighties and ending at the finale of the TurnOfTheMillennium (if it's really ended at all). The movement marked an intense trend towards heavy interest in Eastern Culture, especially Japanese, and its influence therein on American pop-culture.

Somewhat of a counterpart to the BritishInvasion; whereas the BritishInvasion marked a heavy influence of British music and musicians on the music industry, the Japanese Invasion marked a heavy influence of Japanese visual media on American visual media, especially animation and comics.

The Invasion can be noted to have begun as early as the release of ''Film/TheMagnificentSeven'' - a remake of the Creator/AkiraKurosawa film ''TheSevenSamurai'' - in 1960; its counterpart in the animation world came the following year with ''Alakazam the Great'' - the dubbing of the OsamuTezuka film, JourneyToTheWest.

Throughout the 1960s, films from Japan, especially Creator/AkiraKurosawa films, were brought over to the US - at first through remakes, and then as the originals themselves. At the same time, cartoons that would one day be known worldwide as {{Anime}} were dubbed and shown on children's TV as novelty series - most notably, Anime/AstroBoy, Anime/SpeedRacer, and {{Gigantor}}.

Throughout TheSeventies, it was in animation during this decade that Japan began to exhibit its influence on American culture the most. Japanese animation companies had proven proficient enough - and most importantly, ''inexpensive'' enough - that animation studios began outsourcing work to Japan, primarily for Inbetweening. The incoming funds for animation from America, combined with the overall success of Japan's manufacturing industries, created an environment ripe for animation, and established the careers of many of the industry's pillar directors. By the end of the decade, SpaceBattleshipYamato was brought to the US under the title {{Starblazers}}, becoming the harbinger of things to come.

Samurai films continued to be brought over, as a counterpart to Chinese and Hong Kong Kung-Fu movies, but were generally regarded as schlock entertainment, barring the works of Akira Kurosawa. "Ninja" entered the American Vernacular, and became exceedingly prominent in film, TV, and especially comic books. Finally, Japanese films were thrown a saving throw in the last years of the decade, in the form of a ScienceFantasy film known as ''[[Film/ANewHope Star Wars]]''. Heavily influenced by Eastern philosophy and mysticism, Samurai aesthetics, and directly based on the works of Akira Kurosawa, StarWars became the link between the East and the West in storytelling.

Following {{Starblazers}} came the dub, ''Anime/BattleOfThePlanets'', and it became glaringly obvious to US investors that Japan couldn't just create inexpensive animation, but inexpensive ''gorgeous'' animation. TheEighties is impossible to imagine without Japan's influence, as pop-culture of the day was inundated with animation from Japan. Combining Japanese highly-detailed animation techniques with American investment capabalities (read: deep pockets), made possible ''WesternAnimation/TheTransformers'', ''Franchise/GIJoe'', ''WesternAnimation/SilverHawks'', ''WesternAnimation/ThunderCats'', and many other cartoons which pervaded the decade, some of which remain popular even today.

Just as the influx of American funds into Japan helped create the animation of TheSeventies, the greater influx in TheEighties allowed for a boom of animation in Japan, with shows like {{Voltron}} and {{Robotech}} becoming as popular in the US, if not more so, than their American-originated counterparts. Slowly, American audiences became aware of that these shows were part of a distinctly Japanese artform. The seminal moment of anime in the US came with the release of ''Manga/{{Akira}}'' in national theaters. With no localization whatsoever, and shown completely uncut, ''Akira'' forced the American public to acknowledge that Japanese animation was, for all intents and purposes, an entirely different style of animation than Western Animation. In response to this realization came the nomenclature, "Japanimation."

TheEighties brought with it, too, the rise of home VideoGames, and out of the rubble of the VideoGameCrash of 1983 came a small Japanese company who would drive the industry for the next 20 years: Creator/{{Nintendo}}.

The latter half of the 1980s saw more and more imports of Japanese products, as well, with part of their marketability being that they WERE from Japan. Electronic companies like Sony, and car companies like Mazda, didn't try to hide their Japanese roots; instead, they rather reveled in the fact. As Film/BackToTheFuture said it, "the best stuff in the world comes from Japan," had become an accepted truth in the US, superseding the previous belief that the US produced the best products in the world. During this time, the karate craze saw a revival with TheKarateKid film series.

TheNineties saw the height of the Invasion, as interest in anything Japanese-related became hot-selling items, especially Japanese visual media. Fansubs became prominent in media black markets as a way to see "Japanimation" shows which hadn't been brought over to the US. Manga, originally published in left-to-right format in the US, emerged for the very first time, with the most prominent being RanmaOneHalf. Shows were being dubbed and broadcast on television, to varying degrees of success, and those deemed "too intense" for broadcast were relegated to video-only status. And, of course, {{Hentai}} brought to light to the US the idea of [[AllAnimeIsNaughtyTentacles naughty tentacles]], and with it the stigma of AllAnimeIsHentai. By about 1995, however, bad dubbing, bad video transfers, and the ever-present hentai in the children's sections of video rental stores (AnimationAgeGhetto, remember) left interest in Japanese media relatively low. However, the style was granted one last saving throw just as popularity seemed to be waning the most.

First, the rise of Cartoon Network and the establishment of {{Toonami}}, an action-oriented animation block on TV first brought back shows like ''WesternAnimation/ThunderCats'', and then rebroadcast the {{Macross}} Saga of {{Robotech}}; following, it broadcast the original run of ''Anime/SailorMoon'', which proved successful enough to warrant the dubbing of ''more'' episodes which had never been dubbed before. The {{Pokemon}} TV series began airing on broadcast TV, as well, which attracted younger audiences. Finally, it was the broadcast of {{Funimation}}'s newly-acquired series, DragonBallZ served as the HeroicSecondWind for Japanese animation. In the span of about two years, "Japanimation" went from being a dying fad, to the household "anime" that is known today.

Japanese games, especially those from {{Sega}} and Creator/{{Nintendo}}, flooded the market and re-centered the video game industry from California to Japan. Mario and Sonic, two Japanese creations, became the iconic generals of the ConsoleWars, while ''{{Pokemon}}, StreetFighter, Franchise/TheLegendOfZelda, Franchise/{{Castlevania}}, Franchise/FinalFantasy, {{Starfox}}, {{Metroid}}, {{Kirby}}'', and others put the question into the mind of many Americans whether the US would ever regain prominence in the video game world.

The Turn of the Millennium brought with it the advent of TheInternet, and solidified the ubiquity of Japanese culture in the US. Suddenly, these strange foods like Pocky and Ramune become wanted items, which by the end of the decade would become relative mainstays in comic shops and gaming stores. Ebay and Internet shops made it possible to buy products directly from Japan, and these Japanese companies were not blind to the possibility of marketing in the US. While still found primarily in hobby, game, and comic shops, many products, such as snap-together mecha models, vinyl figurines, mini-figurines, wallscrolls, etc. have become as commonplace as American goods, and have only been altered insomuch as being printed with English text.

The full effect on visual media came to a head when Western animation began to adopt {{Animesque}} qualities. Some shows, such as WesternAnimation/TeenTitans and WesternAnimation/TotallySpies played this to the nines, made as stereotypically Japanese as possible, sometimes including Japanese openings. Others, such as MegasXLR used the visuals as an obvious homage to their influences. ''KappaMikey'''s premise necessitated it to be {{Animesque}}. Still others, now the vast majority, like Samurai Jack, WesternAnimation/{{Ben 10}}, and WesternAnimation/AvatarTheLastAirbender, simply were {{Animesque}} because that was the style the animators preferred, without any conscious effort to make an "Western Anime".

TheNewTens, on the other hand, have seen a backlash of sorts, as the Invasion seems to be reeling back from American shores. More recent works are treated by some with either indifference or outright disgust, which was ironically helped by the same ubiquity made possible in part through TheInternet: [[SturgeonsLaw more mediocre works]] became available to audiences in contrast to the [[ImportFilter relatively filtered novelties]] of TheNineties and the TurnOfTheMillennium. Combined with a persistent AnimationAgeGhetto, [[BiasSteamroller the apparent lack of reliable, professional critics' references]], the industry's (perceived) ever-greater focus on [[PanderingToTheBase pandering to the]] {{otaku}} market at the expense of casual and foreign fans, a cynical Western gaming community that tends to treat Japanese games as DeaderThanDisco, and the tumultuous times faced by American anime companies (due in thanks to piracy, NetworkDecay, and the general economy) along with the rough times the general Japanese economy faces (which has been ongoing since 1990), it's no surprise that some pessimistic observers are thinking that "anime is dead" (among other things). But that said, with the resurgence of popularity in eastern gaming, the revival of {{Toonami}} and the continued general presence of Japanese culture, calling the Invasion over may be premature.

Also noteworthy is that Japanese visual media has had an impact on other English-speaking Western countries, particularly Canada, Australia, and to a lesser extent the UK. It is present on mainstream television in Canada and Australia, and works such as Canada's ''ComicBook/ScottPilgrim'' or Australia's OELManga ''TheDreaming'' demonstrate its influence on the media of those countries.
