Billboard -- The Billboard Japan Music Awards were broadcast on TV Tokyo networks on Dec. 15, with popular girl group AKB48 leading the charge with four wins and breakout star Carly Rae Jepsen scoring a pair of trophies.

With over a 100 nominees, the awards were determined by popular vote as well as yearly chart points. AKB48 went home with the same four awards that they won last year, including Artist of the Year, Top Pop Artist, Hot 100 of the Year and Hot 100 Single Sales of the Year, the latter two for "Manatsu no Sounds Good!".

AKB48, known for having over 90 members, released their fourth album "1830m" in August.

Leo Ieiri, pictured at right, won Best New Artist and BIGMAMA picked up the trophy again for Active Artist of the Year 2012 presented by Daiwa House, awarded to the artist most active within the live music scene.
