にほん　の　ぶんか　が　すき　で、　にほん　に　すみたい　から、　にほんご　を　まなびたい　です。 nihon no bunka ga suki de, nihon ni sumitai kara, nihongo wo manabitai desu. I like japanese culture, i want to live in japan, that is why i want to learn japanese. or you could say: にほんご　を　まなびたいです。　なぜ　なら、　ぶんか　が　すき　で、　にほん　に　すみたい　です。 nihongo wo manabitai desu. naze nara, bunka ga suki de, nihon ni sumitai desu. I want to learn Japanese. The reason is, i like the culture, i want to live in japan. I think both means pretty much the same thing. There is probably some difference in what you put emphasis in, but the i dont think it's so big differense :) Hope it helped!
