2PM's fifth Japanese single 'Masquerade' will be used as the opening theme song for Nihon TV's 'Happy Music' in November.

Pre-sales for 'Masquerade' began on the 15th and showed explosive popularity by sweeping #1-3 on Tower Record's chart. They maintained the top three spots for eight consecutive days from October 15 to the 23rd, which proved 2PM's great popularity in Japan. There is high anticipation for their single because more albums were urgently created due to the massive amount of orders. The group has also ranked first on Japan's largest mobile ringtone chart.

Famous Japanese music composers NA.ZU.NA and M.I, who have worked with popular Japanese singers like Arashi, Koda Kumi, and SMAP, have collaborated to produce "Masquerade". "Masquerade" is a dance track about the heartbreaking story of a person who is caught in forbidden love. 2PM's vocals along with the sad melody, bring out the emotions in the song. In the album jacket photo, the members of 2PM have been drawing attention for their masculine charm and anticipation is high for live performances of their 'mask dance' choreography for this track.

The massive popularity of their new single 'Masquerade' is what led to the decision to make it the opening theme song for 'Happy Music'.

On another note, 2PM will be holding an Asian Tour at the end of the year, and at the beginning of next year they will hold  an Arena Tour in Japan.
