Five Elements Ninjas

Five Elements Ninjas (Chinese title: 五遁忍術) is a 1982 Hong Kong martial arts film directed by Chang Cheh. The film is about a Chinese martial arts school that finds itself outclassed by their rivals, so they hire an elite ninja from Japan to destroy the school. The lone survivor of the massacre learns the secrets of ninjutsu and seeks revenge against the ninja. Although only starring one member of the famed Venom Mob in Lo Mang, the film very much is in the spirit of director Cheh's later Venom Mob films.
