Welcome: About


  • I met Mary Nishikawa for the first time at a paper writing workshop held at Kurume University. After receiving kind and useful feedback on my writing, I  requested editing of my English paper to submit to a journal. We chatted in LINE [I could communicate in Japanese with her] which helped in promptly refining the contents. The paper was accepted by my target journal. — Shunichi Kawakami, MS Physical Therapy, Kyushu Nutrition Welfare University/Kurume University School of Medicine Graduate School

  • Ms. Mary Nishikawa had worked as an editor at Nippon Roche Research Center. She advised young Japanese researchers and communicated well with them. I have recommended her to some famous professors, and there is no doubt that she impresses them with her sincere and gentle character. She is full of ability and gets along well with professional people. — Yasuhiro Furuichi, PhD, Biotechnology Division Head, Nippon Roche Research Center​​, GeneCare Research Institute (former positions)

  • I worked with Mary when I was editorial manager at the Foreign News Department of the Medical Tribune. As a medical writer and editor, she wrote and edited many news articles about medical research published in journals such as the New England Journal of Medicine, Lancet and Nature. She is always professional, and her work speaks for itself. she has dedicated herself to our department and without her devotion we could not have produced so many interesting articles.  — Hideto Masukawa, medical writer

  • Mary's talks are well organized and prepared, her voice has a comfortable tone and pitch, and her slides are easy to follow. Yoshiyuki Kajiwara, PhD, researcher

  • Mary Nishikawa's seminar on how to write a scientific manuscript in English was impressive and useful. All of the young investigators were excited to learn. You will have scientific fun communicating with Mary. If you do , you will become a wonderful international scientist. Takemi Otsuki, MD, PhD, Steering Committee Chair, Kawasaki Medical Society
