Ozzfest Japan

Ozzfest may leave quite an impression on Japan next year. The longtime hard rock and metal festival turned a few heads earlier this year when it was announced that Slipknot and Black Sabbath would headline the two-night destination festival in Japan. Now comes word that four more heavy hitters have signed on to play.

The news keeps coming out of the Black Sabbath camp. Not long after it was revealed that the band was planning an April 2013 release and Australian tour, the group was officially confirmed for Japan's inaugural Ozzfest. They'll headline night two on May 12 at Makuhari Messe in Chiba City, Japan, while Slipknot have now been confirmed to finish out night one on May 11.
