Cosquín en Japón (コスキン・エン・ハポン, Kosukin en Hapon) is a three-day South American folk festival held annually in Kawamata, Fukushima, Japan.
In 1955, Yasumitsu Naganuma (長沼 康光), a resident of Kawamata and Argentinian folk enthusiast, formed Norte Japón, otherwise known as the Northern Japan South American Music Alliance (北日本中南米音楽連盟).
In 1975, the Alliance held the first Cosquín en Japón event at the Kawamata Welfare Center (川俣町福祉センター), with 13 amateur groups performing.
During the Japanese hosting of the 2002 FIFA World Cup, residents of Kawamata, at the urging of Argentina, formed a Japanese-style cheer club to cheer on the Argentinian team.
