I love Japan as well even though I've never been there. I hear it is a very safe country with a low crime rate, and very clean as well. Many people live to a ripe old age, and I like the fact that they have an Emperor and the old temples are very beautiful.
I would like to visit Japan someday. The only thing that would make me hesitate to stay there long-term is the earthquakes. Since Japan is on the pacific "ring of fire" they are prone to earthquakes as are other countries that ring the pacific ocean. Despite that, I hope that we both get to visit that amazing land someday.
You complemented my post very well, there is also this, low crime rate, they show a lot of respect and education with garbage, with honor with people, in short, it's a really sensational place, now I feel more like going there too haha.
Earthquakes are also another thing that happens there, it's complicated and I would be afraid of them too.
