There are people called "Ainu" in Japan.　(アイヌ)
Of course they are Japanese.

"Indigenous people of Japan."
　
The only difference with the other Japanese.
It is that they are so called.
　
When translate description "indigenous people" to Japanese.
It become ”senjū-minzoku”. (先住民族)

Meaning of ”minzoku” is ”race” or ”ethnic group”. (民族)
In short，Ainu is associated to them.
　
But they are no different with most other Japanese.
We're the same Mongoloid in racial.
　
However，Japanese of all is a Mongoloid.
Of course，it is not the case.
　
For example，Donald Keene san of master of Japanese literature research.
(include Japan.)
　
1922, he was born in New York.
When World War II，he fought the Japanese as a U.S. Navy officer.
And 2012，he acquire Japanese nationality.
　
He is Japanese.
But he is not a Mongoloid.　

Ainu is a Mongoloid.
However，they has one genetic characteristic.

They has many genetic common with northern Asians than other Japanese.
　

・・・・・・・・・


"Japan is the place of originated of the human race."

By the way，I've never heard this theory until now.
Even if I've heard this theory until now, it would be definitely wrong.
　
Japanese ancestry.
They came from somewhere absolutely.

And until around enters the 20th century，the movement of common people were not many at Japan.

Therefore，the genetic bias by introduction route of people to Japan.
Even if there is little it, I feel a natural to it.
　
Incidentally Ainu is not an ethnic name in first place.
This is fellow by Ainu language.
