If you fully devote yourself to studying Japanese, how hard is it to learn and how long would it take to get to a level where you can hold conversations in most situations without difficulty and express complex ideas? I've asked a few people this question and some people have said Japanese is an extremely hard language to become conversational in and others have told me it's simplier than French and very easy to learn, I'm told people find Japanese hard because it's so different, yet once you get used to the difference Japanese becomes fairly simple and easy to learn.
You thoughts on it?
EDIT: I'm talking about spoken Japanese, I know full well "fluently" writting Japanese is a ***** to learn a takes years.
