Hi! I am a native Japanese who lives in Germany.
Every day, I write academic articles both in Japanese and English, so it is no problem to proofread your writtings. I will finish every job within a day, and I will quickly answer any questions you ask.
Before coming to Germany, I was a research assistant at a University in Tokyo, and I used to translate/proofread the papers written by international students. I know it is tough for non-native speakers to write in Japanese, but I understand the points that they should be aware.
I'm looking forward to hearing from you.
With Best regards
Yuta
