Mammals were tiny shrew-like creatures that lived in the shadow of the first dinosaurs.

Before it split all the continents were together
You and all the other creatures could tiptoe over

It wasn't till after the plates started drifting in different directions that created different land formations and then there was volcanism that created Japan on top of tectonic plates

So yes I am sure at one time point Japan was filled with immigrants and such before it's current status

200. million. years. ago. is. not. 20,000. years. ago.

My gosh, It's the interwebz. You don't even have to know anything anymore. Just search it.
