I'll tell you what has worked for me in the past.
lets say you are looking for "buy car" in japanese
open up google's advanced search and search on "buy car" but change the "return pages written in language to": Japanese
now click on a few of the returned searches, and paste all the Japanese text into a translator like:
http://www.csse.monash.edu.au/~jwb/c...wwwjdic.cgi?9T
the translator will break down each word and translate to english, so you just need to scan your eyes down looking for "buy" and "car" or "purchase" and "automobile"
this method is rather unorthodox, and messy, but if you are really stuck, then I have found it always to work - it just takes a little patience.
Good luck.
