Free music event in Yoyogi Park. There are two stages and a huge host of stalls selling arts and crafts, organic coffee, and, of course, the usual selection of fast food and beer. The vibe is all very free-spirited and hippy-loving with hand-painted murals, open-to-anyone wigwam tents, and so on. Certainly one of the bigger events to kick off the spring, and the fact that it takes places during the cherry blossom season helps draw in the crowds from Yoyogi Park across the road. See the official website for the full-line up of artists. The event runs from midday until 8pm (from 10am on the Sunday).
