Roppongi Hills Sakura Festival 2017

Always one of the most popular happenings on the spring calendar at Roppongi Hills, this 'urban hanami experience' sees 14 of the complex's restaurants set up food stalls around the Arena, where traditional (and less traditional) music performances also take place throughout the weekend. On April 1 and 2, the rooftop garden at the complex, which is usually closed to the public, can be visited for free.
