Mt. Fuji, the pride and center of Japan's heart, extends over both Shizuoka and Yamanashi prefectures. Despite being so far away, it can also be seen clearly from Tokyo.

A Little More RelaxedThe Kansai region as a whole has long been characterised as more friendly and outgoing than Tokyo and this is somewhat true. People in Osaka tend to be a bit more open and generally won't hesitate to speak to you even if you're a foreigner.
