Time Out says
If you're looking for a way to celebrate the long weekend with a bang, this is it: seven years after starting life at Crane's Hollywood Tavern in LA, the mother of all backyard parties finally arrived in Tokyo in 2011. Now in its sixth year (2012 was a no-show), The Do-Over never provides lineup details in advance, maintaining the element of surprise all the way to the end. Nevertheless, expect a tight group of top-grade DJs, free-flowing drinks and tasty grub in the perhaps less than sexy surrounds of Oi Racecourse (aka Tokyo City Keiba). Entry is free, but you need to sign up in advance to get in.
