Asobi Expo Tokyo

Sure, there are plenty of parks in Tokyo, but most of them have rather strict rules limiting how kids can run around, play ball or simply have fun in a natural way. Aiming to provide energetic young 'uns with a space to do just that, this one-day happening in Yoyogi Park opens up one of the spacious lawns for unbridled play – while volunteers will be on hand to make sure things don't get too wild.
