If you are now in Japan you might be interested in visiting the Naruto exhibition which is currently being held at the 52nd floor of Roppongi Hills. The exhibition is opened until June 28th. Not only you will find Naruto and his friends at the exhibition but also in the streets of Roppongi which have been decorated for the occasion. You can collect the characters of the popular TV show that you find in the streets and participate in a “Stamp Rally” contest. You can find more info at the official website.
