Scooby-Doo and the Samurai Sword

The Mystery Inc. gang travels to Japan for a martial arts tournament, racing against the vengeful Black Samurai and his Ninja warriors to find the legendary Sword of Fate, an ancient blade fabled to possess extraordinary supernatural powers. Along the way, they must outsmart Sojo, their bodyguard turned nemesis, and help Daphne Blake's friend Miyumi, who initially betrays them before joining forces. With the help of a sushi shop owner and samurai, Matsuhiro, the gang eventually retrieves the Sword of Doom, breaks the Black Samurai's curse, and saves Japan from his evil plans.
