Japanese with Chieko N.

I am a native Japanese speaker. I'm now living in the USA but also in Japan and go back and forth here and Tokyo. So I know the Japanese trend well from comics to businesses. I have long working experience as engineering manager at some major international companies in japan. I know it is difficult for you to communicate with Japanese workers because there are a lot of business custom differences between Japan and other countries. If you feel something wrong in your communication with Japanese, please let me know it. I believe I can give you some tips on each specific situation. I have the teaching credential of general science for middle and high school students certified by the Japanese University and I have successfully passed the Japanese language Teaching Competency Test authorized by the Society for Teaching Japanese as a Foreign Language in Oct 2016. Regarding the textbooks, I will adjust the textbooks and materials used in my lessons according to the student's level, requirements and goals. I have many textbooks and workbooks for the Japanese language learners which I bought in Japan recently. They include textbooks for the Japanese language proficiency Test (JLPT) N1 -N5.
