umm, if Takeshima played a role, it wasn't that it made the government angry and therefore want to ban K-Pop. let's be realistic here. it probably has negatively influenced popular opinion on K-Pop and the Korean Wave, and therefore has made K-Pop's popularity decrease, which made NHK not feel so inclined to include acts like KARA and SJJD (who are flops this year) and THSK (who are irrelevant).
