Hi,

there are many differences between Japan and the US. The most striking ones are the following:
- land is very narrow, so expect a small room, narrow roads, no big open spaces, many people;
- there are many more constraints here that you just have to accept than in the US;
- if you are a white heterosexual boy, this will probably be the first time you experience being a minority;
- people are more candid and friendly in the US, while human relationships are more complex in Japan

In addition, if you go to Tokyo or Osaka, and you do not come from New York or Chicago, this may be the first time you experience living in a real metropolis.
