There is http://www.google.com/search?sourcei...japanese+guide for incase you want to atleast try to speak to them in their own language
(it makes a difference if JP's see you as tryin' to speak to them in a way they can understand -at least i have seen for me that it does)
... i have a compilation of such guides that has pretty much all i would need to say to a JP person ... of course i can't read the characters, so i try to keep my questions or whatnot simple to maybe just a >yes please< or >no thanks<

Also there are Japanese>>>english dictionarys on the web that you can use to check what a word translation would be ... some links include :
http://www.trussel.com/f_nih.htm and
http://www.freedict.com/onldict/jap.html

I hope this helps ...
