This may have nothing to do with this post, but when I lived in Japan I used go "home" at least once every three years just to see what has changed or not changed as DutchBaka mentioned.
As I, for the last 35 years consider Japan "home", my real home, and I am now in the US, I visit at least once a year and sometimes twice a year until the time comes when I will eventually move back there permanently and probably die there.
To be honest, I would be living in Japan today, but my brother died 4 years ago and I promised him I would care for his dog who was abused and tortured (and missing most of her front teeth, probably from being kicked in the face) and was set for death the day after my brother adopted her, that I cannot break my promise to him or give her to another family who may not care for her as well as we do as she truly is a wonderful companion. Call me weird or crazy, but as much as I want to move back to Japan, I cannot do it yet. I will stay until she leaves this plane of existance. It's the least I can do. After she passes I will return "home".
