Most summer music festivals that claim to take place in Tokyo are actually held off in the wilds of Chiba or Ibaraki. But not World Happiness: this one-day event unfurls on the loveliest bit of landfill in the capital, right next to Shin-Kiba station. Convenience aside, it's also a family friendly affair – there's even a 'parent ticket' for people taking children with them. The fest was started in 2008 by Yellow Magic Orchestra's Yukihiro Takahashi and art director Mitsuo Shindo, and has featured Takahashi and his old bandmates every year since. YMO will be doing their thing again for the 2011 edition, with the group's Ryuichi Sakamoto also appearing in his regular duo with laptop guitarist Christian Fennesz. The bill features veteran acts such as rock trio Little Creatures and hip-hoppers Schadaraparr alongside relative newcomers like indie weirdos Shinsei Kamattechan and Rolling Stones wannabes Okamoto's. One word of advice: it's worth getting your ticket early, as the crowd is segmented into blocks and latecomers risk ending up miles away from the main stage.
