JYJ's return to Japan has set fire to their popularity.

Yoochun's 'Rooftop Prince' was released in Japan as a DVD and Blu-Ray, and it also started airing on DATV. Almost immediately, 'Rooftop Prince' became the #1 borrowed DVD, sweeping #1-5 on the Tsutaya DVD rental charts. Not only that, but a 'Rooftop Prince' cafe has opened in Shibuya. It serves up the�omelette�and yakult that Yoochun enjoyed in the drama, and is one of the hottest places to visit by fans.

On top of Yoochun's success,�Jaejoong's 'Code Name: Jackal' is set to release in Japan soon, and JYJ's label revealed that it was chosen as the #1 most-anticipated movie opening during the week by 96% of voters. His DVD is currently #1 on HMV, Amazon, and the Oricon DVD charts as well.

An on-site manager said, "After JYJ finished their legal battle in Japan and had their successful Japanese concert, their popularity has grown even more. Junsu's 'Uncommitted' ranked #1 on Amazon charts again after the concert even though it was released last year."
