The word "jutsu" is simply a Japanese word for "technique." The idea of ninja jutsus is very common in anime and manga, and definitely predates Naruto. As long as you aren't using a jutsu name copied directly from Naruto, you should be fine (and even some of the names are likely to be public domain, as they are mentioned in Japanese ninja folklore).
For example, the body substitution technique, "kawari no jutsu" pops up frequently in a wide variety of anime and manga whenever ninjas are mentioned. Similarly, I can probably name 5 or 6 animes that use the shadow-clone technique, "kagebunshin no jutsu."
