"We are excited for the opportunity to bring Ozzfest to Japan for the first time ever,” says Sharon Osbourne. “We’ve got the perfect combination of Western and Japanese bands. Ozzfest is also thrilled to be presenting Black Sabbath’s first-ever performance in Japan.”

Despite Japan reigning as the second largest music market in the world, Ozzfest Japan 2013 will represent the first major international music festival to ever travel to the country.

"We are thrilled to open a new chapter for this legendary festival in Japan,” H.I.P. President Massy Hayashi says of the significance of bringing Ozzfest to Japan. “I think it will be the perfect chance to bring together the very best international rock music and also give us a chance to show how far Japanese rock has come in recent years.”
