Yamashita Tomohisa (a.k.a.�Yamapi) revealed through a recent interview that he'd like to work with JYJ's Jaejoong in the future. "Jaejoong and I promised to work together someday. I really want to do it if there is any chance," he said. The two became close while TVXQ was promoting in Japan, even attending a Lady Gaga benefit concert together. Additionally, Yamapi's sister, Yamashita Rina, and his mother are huge TVXQ fans. Yamapi is a member of NEWS, one of Japan's biggest pop groups, and he's contracted under Johnny's Entertainment, Japan's largest agency. He's currently visiting Korea to promote his solo album, "SUPERGOOD, SUPERBAD", and recently performed "Party Don't Stop" on Mnet's�"M! Countdown". He first gained recognition in Korea through his role in "Code Blue", a Japanese medical drama that enjoyed a great deal of popularity both at home and abroad. Gauging his growing popularity in Korea, Mnet Media and Johnny's were in talks about potentially debuting Yamapi. Indeed, both parties were gratified to learn that he was greeted by�over 200 fans at the airport when he flew in a few days ago. When asked about his popularity, Yamapi gave a shy laugh and said, "It's awkward for me to talk about my popularity with my own mouth. My goal is just to work hard and receive the fans' love." Yamapi also promised fans that he'd "study Korean hard" so that he could create a full Korean album soon. Source: SPN, TV Report Tip: Cindy, Yae
