‘Hate Korea’ and ‘Hate China’ as Taste-Net Right and Nationalism in Contemporary Japan In this article, I examine the emergence of Net Right and their nationalism, represented by ‘Hate Korea’ and ‘Hate China.’ Although 2 Channel, the most largest anonymous internet forum in the Japanese-based internet, is considered to be the source of Hate Korea and Hate China movements, it is impossible to consider 2 Channel as Hate Korea and Hate China intrinsically, because those posts are only a part of 2 Channel. Net Right, referring to people who continue to leave right-wing posts repetitively, expressing hate South and North Koreas and China as anti-Japan countries or ‘specified Asia’, emerged from 2 Channel since the early 2000's. They are clearly differentiated from existing right-wing activists, in that they are centered on the internet and do not express the respect toward the Imperial House of Japan. As conlcusion, I argue that ‘Hate Korea’ and ‘Hate China’ in the Japanese-based internet reflect a new kind of nationalism, so-called ‘nationalism as play’ and the gap disparity in contemporary Japan. Therefore, it is necessary for us not only to examine the discourses of Hate Korea and Hate China, but to pay attention to the backgrounds that Hate Korea and Hate China have emerged from.
