Japan

You once had to move to Japan, well, that's how circumstances worked out.

You're in middle school, and you've become friends with Japan. You get along really well, hang out together, go to art class, and are in the same class. A few months have passed since you've been living in Japan, but one day your friend doesn't show up for class. You didn't notice, but it bothered you. You asked the class teacher why Japan hadn't come, but she just shrugged and said she didn't know where she was or why she hadn't come. So the class ended, and you went home. It was already dark and cold, and suddenly you saw Japan (and then you were on your own).
