the Namikaze clan is wind type chakra based...
their specialty is the ShunShin no Jutsu / Body Flicker Technique..
Later, Yondaime modified it, thus he created the Flying Thunder God Justu..
the Shunshin no Jutsu was later then passed on to Kakashi Hatake, and to Obito too, but he died... :kakashi:
Namikaze Clan is now gone in Konoha.. Naruto was supposed to be the last of Namikaze, but since he took after his mothers last name, which Uzumaki.. so that makes Minato the last of his clan... unless there are still others left, which i doubt of... :kakashi:
