have you ever been to Japan?
I've never been anywhere in the Pacific Ocean over there.
I think it would be a really neat place to visit.  I have never even been out of the country. That would be a neat asian country to visit though
 The country is divided into 47 prefectures in eight regions
Is that like cities?
More like states and counties.    The population of 127 million is the world's tenth largest.
wow thats huge!  
Japanese people make up 98.5% of their population
Wow so Japan is made up almost entirely of their own people.  Not much diversity there.
Worldwide, approximately 129 million people are of Japanese descent; with only 4 million outside the country.
