A number of high-level defectors from the Democratic People's Republic of North Korea have stated that 3 Ninjas Kick Back was a childhood favorite of Kim Jong Un, now Supreme Chancellor of the DPRK. He was apparently so taken with the film that his father, Kim Jong Il, reportedly commissioned a remake with Korean actors.
Despite being released before 3 Ninjas em Apuros (1995), this film was actually shot at a later time.
Michael Treanor was unable to return as Rocky because he had quit acting by then.
Despite being set in Japan, all the Asian songs on the soundtrack are Korean.
Max Elliott Slade was the only brother from the first film, to return for the second film. Michael Treanor and Chad Power did not return and were replaced by Sean Fox and J. Evan Bonifant.
