With cherry blossom season running late this year, it looks like the revelers at Harukaze 2012 will have to enjoy their hijinks without the hanami this time around. But never mind: this free party still promises to be a lot of fun, with a wide range of bands and DJs playing across three stages during the weekend, complemented by a skate ramp, market stalls, NGO booths and vendors selling hippy-friendly food and drink. Acts to look out for include reggae singer Likkle Mai, '70s-style fusion jam band Sardine Head and a jam session involving Rovo violinist Yuji Katsui, and there'll be a 'parade with no name' through the streets of Shibuya from 2pm on Sunday afternoon. The organisers hope to encourage punters to 'consider [contemporary] issues from alternative cultural perspectives', and they've hit on one neat alternative wheeze of their own: the event is being powered by fuel made from – wait for it – PET bottle caps.
