The difference between Ninjutsu and Aikido essentially would be that Aikido is a fairly modern martial art. And Ninjutsu has a little bit longer history. Essentially, there are some similarities between the philosophy and certain elements of movement. Of course, there are similarities between all Japanese martial arts. Maybe one major difference would be that we wear black gis. And Aikido usually wears a white gi. Yeah, that's just a little bit about the difference between Aikido and Ninjutsu.
