Just saying, the translator usually fails. XD; The best thing to do is learn the said language as well as you can and it'll be right. :3
Well it's hard to teach a language like Japanese in such a small game, so, considering there were only 100 lessons, I did pretty well. XD; I think I could've gotten to speaking level if I continued and then I could've done some kind of after-school class to continue my Japanese learning further. :3
