All these 8 regions can be good places to visit, but can anyone visited these regions understand Japan may be a bit over statement. Japan and its culture is very complex and must be hard to fully understand for foreigners by just visiting some regions. One thing you may agree is that there are two different perspectives of Japanese culture characteristics. One is the traditional perspective, the other is current ever changing perspective. These two are mixed in so many layers To form today's Japan. So you may want to experience both, in order to grasp what makes Japan so Japan. For that purpose, even if you have only limited time in Japan, you can enjoy experiencing these two different perspectives in just going around in Tokyo. You just need a real good guide who can show you around with deep knowledge of Japanese culture.
