Japanese book translation

I am looking for an English editor who can edit the English manuscript comparing the original Japanese book. The book is of the non-fiction genre, so the translator should be knowledgeable of relevant terminology in the subject area. There is no specific deadline for this project, so the translator will have the flexibility to complete the project at their own pace. The translator should strive to translate the nuance of the book as opposed to just a literal translation. Experience in Japanese book translation is preferred.
The original Japanese book is selling on Amazon Japan. Thank you.
