hi kaesarx before u starts learning japanese, lets check points. first, japanese have two kinds of letters (50 each) and uncountable Kanji charactors. maybe this is ur first and biggest barrier of ur japanese learning. however u speaks Spanish, so i think u can pronunciate japanese naturally. i think grammars r not so special. then, japanese has too many kinds of pattern to expless. between men/women, casual/formal/business, colloquial/literary or so. therefore i think u need to decide what do u want to do by japanese. if u want to read something, read them. if u want to read something, watch them. if u want to talk, do it. u can get a lot of stuffs about/made in japan on the web. good luck..^^
