Is Japanese language mixture of Altaic-Tungus & Malayo-Polynesian? Are Japanese people the mixture of normadic people from East Siberia and Pacific islands?

Of all native Japanese I've met in person or in internet forums,nearly all would answered Korean peninsula,China's NE region/coastal region ( Jiangsu/Zhejiang provinces ),and some Pacific Islands plus indigenous Ainu.

What do you expect from this forum for a such question?
Most likely you can still get better answer from wikipedia, or you can try here:

rockbatam, trolls such as Sacima, aka Lucifer, expect flames and bickering to fulfill their emotional complexities that come from their mental retardeness. Don't try to communicate with an individual such as he. For mental rejects such as himself only speak the language of a mental reject.

thanks for info.
I was bit naive.

maybe this might help a little bit
