Weaboos - I need your help!

I'm a highschool senior in an international studies class. A group of Japanese students is going to visit my school, and I get to lead one around and show them my disgusting American lifestyle and school curriculum and whatnot. Based on my teacher's assumption and previous experience with this type of thing, he's told us that the Japanese students probably won't know a whole lot of English, or will understand it but be rather shy about speaking it.

Anyway...I would like to know how to say a few basic things in Japanese, or know a few basic customs, etc. etc. And I'd like to learn it from you guys, for purposes of amusement and because I don't trust phrasebooks (as if Anonymous is more reliable). Also, for those of you who know what you're talking about, what would a Japanese student travelling to the US expect out of their American hosts?

Also, instead of trying to make them feel comfortable, should I just kidnap them? There's about 40, I think I could start a decent shoe factory/ninja clan with that many.

Lol, they came today. It was the most kawaii fucking day of my life.

First of all, the girls were all wearing the full-on, stereotypical Japanese schoolgirl outfits. They all had cool cameras and phones and mini computer dictionaries. They hardly understood us at all, and were very shy about speaking. Then I took three of them (girls) to my sculpture class and I gave them clay. One of them copied what I had been making, and another one made a cute little elephant. My friend was acting like a fool so I told them "He is crazy." to which they giggled and literally responded, "Rearry!?" Then my friend made a hideous clay bird for them, which they liked, and returned his gift by making an origami crane. Anyway...The whole day was sorta like that, and at the end, I got their email addresses :D

Thanks for your halp, Anon, I didn't use any of it but whatever :)
