Wow. I just got back from my two-week homestay in Japan, and man was it amazing! I finally feel like I understand some of the stuff on this forum after going to Japan...and found out I was worrying about the dumbest things! Yes, I was a monster, because my host family was all around 4'8" or so and I'm 5'10", but it wasn't a big deal. No, my host parents didn't speak English, but I did have a dictionary/phrasebook and we made do. Well, long story short, it was awesome! Definitely the trip of a lifetime. I'm now considering moving to and working in Japan. Any comments?
The only thing I can think of to say is make sure it's something you really want to do. Same thing was told to me when I decided to go to Canada for college.
