In May, I went to a concert of K-pop artist for the first time with my friend. That artist is a girls group called TWICE. Unlike Japanese girls group called idol, singing and dancing were both very good and surprised. TWICE is somewhat distinctive and there are some differences from other Korean groups. That means that three of the nine members are from Japan. Not only from Korea, there are other members from Taiwan. It is a multinational group. In the talk scene, Japanese members talk to audience in Japanese. So we can communicate with the members at the concert. It does not happen that Because you can not understand Korean, you do not know what they are talking about. I did not know that much about them, but it was very famous in Japan, I was listening to songs sometimes and not only singing but the content was so much fun that concert was very interesting. They plan to hold a concert again in autumn, so I would like to go again.
