I am extremely interested in the history of Japan.  Do you know anything about Japan? Have you ever been there or want to visit in the future?
I know the first people were more than likely from prehistoric times.
Cool. I am also interested in prehistory.  Would you say they were first there in the Paleolithic, Mesozoic, or neolithic era?  Where did they come from before they were in Japan?
I would say the Paleolithic era since tools were first used and humans kinda sprang up during this time.
Ok, I can accept that answer.  So the first Japanese were probably hunter gatherers who moved from place to place in search of food.  I guess they found rice there. Is rice native to Japan?
I am really not sure but I know its the most important grain for nutrition and for calories and that over 20 percent of calories come from rice so I know rice is very important to Japan.
