There's still no trailer for Kei Nakata's Tsurugi: The Future Swordsman (Tsurugi) on the official website for the movie, but there are a few stills from it. The movie's principal cast is as follows: Yasuhisa Katô, Natsuyo Kanahama, Kenji Matsuda, Asuka Shimizu, Takayuki Katô, Kôichirô Takami, Sanae Kikuta, Masaki Sawatari, Tatsuya Horiguchi (who was also the movie's stunt coordinator), Kazuo Misaki, Masayuki Yamamoto, and Kazuhiro Nakahara. Kentarô Nojima scored the movie, and DIAMOND☆YUKAI composed/performed the theme song for it.
Nakata is the grandson of actor Kôji Nakata, and the nephew of actor Hirohisa Nakata. He himself has acted in a number of movies, including Katsuya Matsumura's All Night Long 2 (Ôru naito rongu 2)
