Shingo Katori, one of the members of Japan's top pop group SMAP, stars as Ninja Hattori-kun in the latest live-action adaptation of the hit manga / live-action TV / anime series. NIN X NIN Ninja Hattori-kun The Movie was a hit when it was released in theaters last August because this latest adventure maintains the tongue-in-cheek humor that has made this character so popular for the last 40 years! Hattori-kun becomes the classic "fish out of water" after he decides to travel to Edo in the hope of perfecting his skills. He gets more than he bargained for when he finds himself transported into the strange world of modern day Tokyo.
