Northeast Asian cultural regionalisation claims contentious roots throughout many periods of Asian history, yet this regionalisation process has noticeable new connections to modern and contemporary globalisation; here we find significant increases in economic transactions and cultural interactions in the region during the 1970s and the 2010s. The purpose of this chapter is to analyse Asian cultural commonality, difference, and asymmetry through the exportation of anime and its arrival on television in South Korea. At the same time, Koreans have indigenised, plagiarised, recombined, and managed to create huge fandom networks to elaborate on this transregional visual culture, from the high postwar period to the present. The chapter highlights an integrative transregional animation culture, the impact of Korean fan culture related to Japanese anime, and their appreciation and recombination of the source material—through fan sites and amateur production—in an age of increased xenophobia between the two nations.
