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.
