This one got under the radar for me. Fuyuhiko Nishi served as the fight choreographer on this one, directed by Tsukasa Kishimoto

Ken is a dancer traveling around the world in search of the ultimate form of dance. His journeys lead him to Okinawa where he becomes a pupil of an old man named Iwao Shinjyo, an Okinawan dance master. "A good dancer is also a good karate fighter," Iwao explains. At the core of his dance teaching is the art of Okinawan karate. The more Ken dances under Iwao's guidance, the more his movements take on the form of Okinawan karate.
