It's Ok. It takes time to master a foreign language, at least you are better than me coz I'm still struggling to learn the basic, I think the process will speed up if I get a good Japanese language instructor but in my local place it's very hard to find one. Recently I can only reckonize some of the words and pronunciation but luckily Nihongo still utilize a large portion of traditional mandarin so we can still understand the definition in certain case.
