Group 2PM and 2AM rose to No. 5 on Japan's Oricon charts with their hit song, "One Day."

A recent documentary on the group, "Beyond The Story of One Day 2pm & 2AM," helped raise their profile into the top 10 spot on Oricon Billboard. The two groups jointly released the song and sold over 55,000 copies.

The documentary gives viewers a sneak peek into the lives and workings of K-Pop bands, and is now a full-fledged representative of K-pop.

2AM commented on the documentary, "You'll see a very different side of us that you can't see when we're on stage. We're all very candid and we have so much we want to share with our fans."

2PM continued to say, "We used to collaborate a lot with 2AM, but we've been so busy lately, it was difficult to do that. I'm glad we had this opportunity. I hope the viewers will get to know us better."

Both groups are scheduled to perform at Seoul Olympics Park Gymnastics Stadium sponsored by JYP, part of the 2012 JYP Nation tour.
