CNBLUE made their debut in Japan last year and last week we reported that they would make their comeback in Japan with a new single titled 'I Don't Know Why'. The single was released earlier today (16th) in Japan and contains a bonus track titled 'Lie'. CNBLUE will be having a live tour all over Japan, and the concert tickets were sold out within minutes. The three locations for the concerts include 'Namba Patch' in Osaka on the 16th (7PM), 'Bottom Line' in Nagoya on the 18th (6PM), and 'Shibuya-AX' in Tokyo on the 20th (6PM). Thanks to Jasmine for the tip and remember to support the group by purchasing the music. [gallery]
