In case anyone else wants to replicate this process (or in case I come back here because I forgot what I did), here's what I did to create it:
- I went to https://manual.toyota.jp/century/ and downloaded the manual - the page is in Japanese but your web browser should be able to translate it. There are three manuals listed with somewhat random looking production dates on them... my car is a 1998, so I just chose the earliest one ("August 2010 to July 2011" - file is century_201008.pdf)
- The PDF file has a password if you want to edit or convert it - I removed this using Cisdem PDF Password Remover (sorry Toyota!). Weirdly, the PC version refused to remove the password, but the Mac one worked
- I used Google's document translation service to translate the PDF. Unfortunately the translation service has a page limit of 300 pages and the manual is 344 pages, so I used Adobe Acrobat to split the document into two, translated them separately and then joined them together again
- I went through this same process for the separate "rear seat" manual (century_sheet_201008.pdf) and the navigation system manual (century_navi_201008.pdf)
- The whole thing was translated by a computer so it's not likely to win a Booker Prize
- A lot of the formatting is weird due to English not taking up quite the same space as Japanese
