Despite these continuing controversial and hurtful issues, Korean pop culture is very popular in Japan. Dubbed the "[[Korean wave]]", Korean singers, movies, and television dramas are avidly consumed. The [[Nihon Keizai Shimbun]] attributes the success of Korean wave to the pioneering efforts of [[Winter Sonata]], which has been avidly consumed by Japanese people especially of women 40 years or older. A novel based on the drama has sold over 1.2 million copies and over 400,000 copies of DVD compilation has been sold. However, there has been a backlash; a book published in 2005 was usually translated as "[[Manga - Hating the Korean Wave|Hate the Korean Wave]]". It sold well enough that a sequel was released.
