Does Naruto have Earth as chakra nature? During the fight between Neji and Naruto, Naruto comes out of earth to finish his final blow on Neji. So does he possess earth element as his chakra nature?
No, in that particular fight, he just (dug a hole and) hid underground to surprise Neji.  No part of that used Earth chakra or Earth jutsu.  I don't think he even knew any Earth jutsu.  He eventually got access to all chakra types due to the Six Paths mode, but still, he was never seen doing any specific Earth jutsu.
