International acts Weezer, Fall Out Boy and Franz Ferdinand are among the first acts confirmed for headline slots at this year's Fuji Rock Festival, Japan's leading annual outdoor music event.

The 13th edition of the festival will take place July 24-26 on its usual site at the Naeba ski resort in Japan's mountainous Niigata prefecture. Tokyo-headquartered promoter Smash Corporation, which stages the event, has also confirmed Patti Smith and Ben Harper for this year's festival. Fuji Rock traditionally attracts a total audience of around 100,000 over its three days.

Animal Collective, Bad Brains, The Melvins and The Funky Meters will also be playing the 2009 event. The festival also features a dance/electronica element, which this year will include overseas acts Basement Jaxx, Royksopp, System 7 and Simian Mobile Disco.

As always, the festival bill will include a smattering of international performers with Japanese links -- this year including Canada-based, New York City-born singer/songwriter Justin Nozuka, whose mother is Japanese. And Northern Ireland electronica act Japanese Popstars will also be on the bill -- although their Japanese connection stretches no further than their chosen name.
