I've been to Japan at least 11 times, never for any great length of time (9 days at the most). I look at it as there being 2 versions of Japan as far as experience; basically the foreign version (in my case American), and the Japanese version. Unfortunately, mainly because I don't speak the language, I fall into the American version. To give an example, take any American movie where the characters for one reason or another go to Japan. It's still an American movie from the perception of an American irregardless of the sights and sounds projected. Take a Japanese movie or TV show, that may even have scenes from the same location, and there's a completely different atmosphere. The language, music, etc. Everything else can be exactly the same (seeing same buildings in Tokyo, or seeing Mt. Fuji), but due to which country is producing the program will make a difference in the overall atmosphere.
