There are two common types of e-books for Japanese novels: EPUB and PDF. EPUB is a reflowable e-book format where the text itself can be read, making it easier to preserve the chapter structure after translation. There are two versions of PDF: one is the text version exported by the publisher, and the other is the picture version obtained by scanning the book. The processing focus of the two is different. Choosing the right path first can save a lot of rework time.

After reading this article, you will be able to distinguish how to process Japanese EPUB and PDF, know whether to choose translation only or bilingual comparison when outputting, and also know which parts of the translation need to be checked by yourself.

Before you start: Confirm these points first

  1. Confirm that the file can be opened normally: Use the reader to turn a few pages to see if the text, table of contents, and illustrations are normal. If the file is damaged or the pagination is disordered, the translation will also have problems. Eliminating this first can avoid detours.
  2. Check whether there are encryption restrictions: Some genuine e-books are copyright protected and cannot be exported or imported. In this case, you should deal with it through the formal method of the book purchasing platform or reader, and do not try to bypass the protection.
  3. Determine whether it is a text version or a scanned version: Try to select a piece of text in the PDF and copy it. If it can be selected, it is the text version; if it cannot be selected and only pictures can be seen, it is the scanned version. This determines whether you need OCR to assist in checking the original text.
  4. Determine the purpose and output method: For personal reading, you can choose translation only; when you need to check the settings and terminology against the original text, choose bilingual comparison. The translation is recommended for personal use only and is not intended for public release or sale without authorization.
  5. Pay attention to vertical arrangement and phonetic notation: Japanese novels are sometimes arranged vertically, and there may also be jingana (small phonetic characters) in the text. How these contents are presented in the translation should be read page by page in the results, and do not assume that there is no problem.
