I just spent a six-month internship in Japan without speaking the language. People there are very polite and helpful. They will take as much time as necessary to understand what you want to say.

And while you're there you'll automatically learn some of the greetings and words in the local language. Try to apply what you've learned and they'll be delighted to see you try to speak the language.

If you ever get the chance to see the world, don't let something like a language barrier hold you back. Just go.
