October 20th, 2014I’m not in Japan yet, but since I’m going there for Mars, I think I can answer you a few questions:
1. Japanese people eat far more than only sushi.
There are so many kinds of dishes with noodles, rice and fish you shouldnt fix yourself on something that can be found so often abroad. But naturally, you will be able to eat some when you are in Japan.
2. If you had enough Luck to be able to visit a Miku-Concert during holidays or such, be aware of the fact that most japanese host-families won’t like it, but indeed prefer to show you a bit of the country, also shrines and temples.
As an exchange student, you can’t just easily take a day off to go to a concert, since you are there for school and not to live some Manga-Pop Culture.
3. Your host family usually speaks a bit English but it is an advantage for you and your japanese if they don’t, cause you’ll learn to express yourself in Japanese then instead of always falling back to english. They will understand if you make some faults and helpfully correct you.
4. Let the Japanese people decide your name. If they really have problems with it they’ll tell you and you can find a solution together, but already starting with a changed name could be seen as offensive and strange.
I don’t know if there are any other reasons for you to go to Japan, but as far as I can see my conclusion for you would be to plan a trip or somthing to Japan, where you can plan everything yourself rather than visiting a school there.
But I know neither you nor can I say much about you, and it still is your choice ^^
BTW: If you already have a Japanese friend, have you already asked him those questions?
Hope this can at least help you a bit then °v°
