I lived in Japan for more than 6 years and also got N1 level on it's language test. I have studied Japanese in Malaysia for 2 years , 4 years of University and worked 2 years in Japan therefore i know all sorts of Japanese grammar and vocabulary. I might not be native but I can assure you that my pronouncation is fairly good. As for Chinese and English they are both kind of my mother tongue because I have been speaking it since young. So I am confident I can help you with all 3 languages. I would love to have a good conversation with you and fix your grammar , vocabulary and of course pronouncation along the way. I usually don't assign homework but I will ask you questions upon your next class. Please contact me if you have any questions!
