Hello! I'm new here. I'm not really a frequent flyer, but I have a business trip coming up and need some advice about the travel. This seems to be a good place to get that sort of thing, so here I am.

I'm going to be going to Japan. Pretty sure the Tokyo area, but I don't know which airport I'll be flying into/out of yet. I think likely Haneda?

When I arrive, what can I expect from the customs agents? Is it going to be difficult because I don't speak Japanese? I've traveled outside the US before, but only to English speaking countries, so I really don't know what to expect where that's not the case. I am going to try to learn a bit of Japanese, but this is a sudden trip, so I doubt I'll be able to get anything beyond a few basic phrases (like "please," "thank you," "hello," "goodbye," and "where is the bathroom?")

What about security when I leave? I know the drill in US airports (as much as that's possible...), but have no idea what to expect in Japan. Is there somewhere I can find that information?

Of particular interest to me is how breastmilk is handled. I will have several days worth of it with me when I return. I will need to have it frozen, in order for it to not spoil on the trip, and would prefer to avoid having it go through the x-ray. I've done that before in the US. Is that an option in Japan?

Also, does anyone know if it's going to be a problem with customs when I get back in the US?

Thank you very much for any assistance you can provide me!
