it's nice to see people apologize for confunding a bit things.

As for ANCIENT Japan, did you know that Japan does not "appear in History" until 57 AD and the first reference comes from Chinese histories, where it is referred to as "Wa."

Due to their division, Japan is a late-comer in Asian history, they started writing their histories around 600 AD and this historical writing culminates in 700 AD in the massive chronicles, "The Record of Ancient Matters" and the "Chronicles of Japan". These chronicles tell about a legendary Japan, deriving the people of Japan from the gods themselves (oh, well, I already heard this story somewhere else).


Some questions stay open (if you want to bother...):

Where did the Japanese come from? Why did they settle the islands? How was it before history was written down?
