Anime Expo announced yesterday afternoon that Morning Musume’s 3,2,1, BREAKIN’ OUT! will be the official song for this year’s Anime Expo. The group will be performing as a musical Guest of Honor.

The song was written and produced by producer Tsunku, who had this to say about AX:

I wrote this song just for Anime Expo® 2009. I imagined everybody’s smile when I wrote it, and I’m looking forward to seeing you guys at the MORNING MUSUME concert. I hope new great energy will be born at the convention from this collaboration between Japanese and US culture, and that it will last into the future.

A sample of the song is currently available at JapanFiles.com’s MySpace page. You can also pre-order the album Shouganai Yumeoibito at JapanFiles.com, which contains the song, and PLATNUM 9 DISC at this time. Both physical CDs will contain a random member’s photo card.
