im not sure if rasengan is considered a jutsu or not, since it doesnt actually involve hand seals, its just a ball of chakra, but if it is, then its ninjutsu

i wonder if the 64 hands of hakke and gentle fist actually fall into ninjutsu though.....it seems in the naruto world, alot of things that involve hand combat go into taijutsu regardless of the manner in which chakra is involved
