The festival will feature Korn headlining on the first night and Black Sabbath taking the top spot on the second night. Sharon had this to say in the promo video, "Ozzfest will be back in Japan on Nov. 21 and 22 and this will be Black Sabbath's farewell. We're also announcing Korn, who are celebrating their 20th anniversary. Now you can't miss that."

While it sounds like Ozzy Osbourne's wife and manager was announced that this would be the final show in the legendary heavy metal band's career, media outlet are speculating that this will be their final Japanese appearance and part of their overall retirement tour plans.

Ozzy addressed the band's retirement plans in an interview with Metal Hammer last September. Speaking about the band's relationship for their latest studio album, 13, he also explained their final plans as a band would involve another album and tour.

"The whole Sabbath experience this time around was great We all made friends, we didn't f- around," Ozzy said, "We all knew that we had a job to do and we did it. It was a lot of fun. So we're going to do one more album and a final tour."

The next month, Ozzy told Times-Picayune, "I'm doing one more Black Sabbath tour, one more Black Sabbath album, and then we're disbanding the name, I believe. And then after that, I'll be doing my solo stuff."

He also expressed his hope that the farewell plans would involve original drummer Bill Ward. "It would be great for him to get it together and sort all the problems out for the next tour," Ozzy said. "It would be a great way for the four of us to end such a wonderful experience of being Black Sabbath, and what we achieved."
