Japan is cool and beautiful! It is kind of weird in a very nice way. It is modern and traditional in the same breath.
People of this nation have tremendous self respect and have pride in their humility. Seeing all that really makes you look into your own values. There are a lot of good things one can learn from the Japanese. One very simple thing I like is, “respect everyone and everything”.
If you are going to Japan for vacation make sure you get Japan rail pass. It is a steal.
For me, the magnificent 富士山 (Mt. Fuji) is quintessentially Japan. Mt. Fuji is the first thing that comes to my mind when I think of Japan. And yes of coarse, how can I forget the legendary bullet trains? :).
