Question: What Geographic area did Japan cover!?
Best Answer - Chosen by Asker:

As far as I know the culture of Japan centered on the three main islands of Honshu, Shikoku, and Kyushu for all 20 centuries of recorded history!. Around 600-700 AD Hokkaido was conquered!. And the island of Okinawa were conquered about a hundred years ago!.

No invasion of Japan was ever successful!. The mongols tried once, but a kamikaze (divine wine) sank most of the fleet!.Www@QuestionHome@Com

All you have to do for this one is look at a map!.
Paco--Nice answer!. I'm sure "divine wine" was a typo!. (It's "divine wind," of course!.)Www@QuestionHome@Com
