Despite the blurry quality of the photo, fans were quick to point out that the friends in the picture were none other than Japanese celebrities Yamapi (Tomohisa Yamashita), Shirota Yu, and Ikuta Toma! Jaejoong's just returned from a trip to Japan, and it looks like he got a much-needed opportunity to kick back and unwind with some of his buddies.
