Yesterday Japan’s MX TV Japan aired this episode of K-BEST that featured JYJ. They have also done a feature on JYJ on February 27th (found here with English subtitles).
Even though there are no subtitles, the episode is mainly comprised of the members performing on stage. This episode mainly covered the Seoul Showcase held on October 12, 2010. It quite thoroughly cover the Showcase, showing clips of the members performing Be the One, Found You, Be My Girl Remix (including the dance moves^^) and Empty. The MCs also complimented JYJ and their popularity– Yuchun on the love he enjoyed in the drama Sungkyunkwan Scandal and the award he received, Jaejoong on the Telecinema Movie Heaven’s Postman, and Junsu on his musicals.
As in the previous episode, a huge picture of Jaejoong is displayed next to the TV in the MC’s talk room ^^…

I’m very thankful to this program Japan K-Best for giving due recogniton to JYJ for the 2nd time. What an awesome 6.4 min of JYJ feature on tv broadcast. I hope there could be one like this in Korean TV (except Arirang TV which also feature JYJ sometimes).
