Since we had such a great reception, we’re already in dialogue about a 2014 Ozzfest Japan!" H.I.P. promoter Kaori Hayashi adds, "I feel we created a perfect storm with an amazing Japanese and international lineup." "It was an extreme honor to have been invited to play the first show of two shows at the first-ever Ozzfest in Japan," says Clown from SLIPKNOT. "It's always a beautiful thing to be a part of something that is brand new for the fans. As always, our love for the Japanese people goes without saying, and we are relieved that we finally got back to Japan. Everyone went off at the show, making it completely incredible…but it’s always like that when we go to Japan. Thank you to everyone for having us and you can rest assured we will always be back. We love you." Billboard Japan had this to say about Ozzfest Japan: "Many music fans have been hoping and waiting for years for Ozzfest to come to Japan…from SABBATH reforming at Ozzfest Japan to the new BLACK SABBATH album, the first thing I want to do is thank the 'gods of metal' from the bottom of my heart for this wonderful sequence of events."
