Following BoA's successful Japanese debut, K-pop group TVXQ (동방신기, known as "Tōhōshinki" in Japan) debuted in Japan in 2005 under a procedure similar to BoA's. TVXQ did not promote that they were Korean and their ballad-style songs fit well into J-pop's typical sound. TVXQ's first and second albums released in Japan were minor successes, peaking on the Oricon Charts at twenty-five and ten respectively. However, on January 16, 2008, TVXQ reached the top of the Oricon Charts with their sixteenth Japanese single "Purple Line". This made them the first Korean male group to have a number-one single in Japan. They have since had remarkable success with their comebacks. In 2018 they even beat the legendary Japanese band B'z by accumulating over 1.2 million people to their concerts. Since the start of the Korean Wave, the Japanese market has seen an influx of Korean pop acts such as SS501, Shinee, Super Junior, Big Bang, KARA and Girls' Generation. In 2011, it was reported that the total sales for K-pop artists' increased 22.3% between 2010 and 2011 in Japan. Some Korean artists were in the top 10 selling artists of the year in Japan.
