The popular Japanese music group AAA announced Tuesday it will split up on Dec. 31, with the five current members planning to pursue solo careers.

After its debut in 2005 with the single "Blood on Fire," the group, which previously consisted of five men and one woman, achieved mainstream success and made seven appearances on NHK's annual "Kohaku" song festival on New Year's Eve.

The announcement comes after the departure of group leader Naoya Urata, 37, on Dec. 31 last year.

The remaining five are all in their 30s and decided to take their careers in different directions, the group said.

"It will be a sudden announcement to everyone who always supports us, but we will continue to give our best performance with the same thanks this year," the group said in a statement.
