Just like Canada, America, or anywhere else, no one city is going to give you a wholistic Japanese experience, but that doesn't mean you can't have a full and complete experience somewhere. I worked in an office with a handful Japanese people. One was from Hokkaido, a couple from north Honshu, one from Tokyo, one from Wakayama, one from Hiroshima and one from Kyushuu. It was funny how the spheres of knowledge for NATIVE Japanese people was very limited. People inthe east knew the east intimately, but people from the west had no idea what they were talking about. I could talk about Kansai with the person from Wakayama, but places and things I assumed all Japanese knew were complete mysteries to those only a couple hundred miles away.

As a JET you are never going to know about all of Japan, but you will get to know about someplace intimately.
