The first ever Ozzfest in Japan is set to debut May 2013. The festival is born out of a partnership between Sharon Osbourne and Japanese promoter, Hayashi International Promotion.

The two day festival will take place the weekend of May 11-12^th at the Makuhari Messe arena, just outside of Tokyo. Headlining day one will be Slipknot, while day two headliners will be Black Sabbath (featuring Ozzy Osbourne, Geezer Butler, and Tony Iommi). The rest of the lineup remains unknown.
