Three times
American all the way in this case. She wnats to experience your country and be farewelled in true American style. Good memories for her to broadcast on her arrival in Japan.
As part of the farewell party/dinner, make a speech, and mention that you wish one day that you can go to Japan to visit her.
Let her know that you are very interested in the culture and country.
Keep in touch. Email's, regualr letter's, exchange books, etc.
You are lucky that you have a friend soon in Japan, and she is lucky that she has one in America.
EMBRACE!! Both be very happy that you have known each other..
A gift is from the heart.. Make sure that you include an American flag for her, and even better, An Australian one
Good luck to you and good luck for a safe flight for Shiori
