More about the research:
In recent years, more archaeological and genetic evidence have been found in both eastern China and western Japan to lend credibility to this argument. Between 1996 and 1999, a team led by Satoshi Yamaguchi, a researcher at Japan's National Science Museum, compared Yayoi remains found in Japan's Yamaguchi and Fukuoka prefectures with those from early Han Dynasty (202 BC-8) in China's coastal Jiangsu province, and found many similarities between the skulls and limbs of Yayoi people and the Jiangsu remains.[8] Two Jiangsu skulls showed spots where the front teeth had been pulled, a practice common in Japan in the Yayoi and preceding Jōmon period. The genetic samples from three of the 36 Jiangsu skeletons also matched part of the DNA base arrangements of samples from the Yayoi remains.
Surprisingly, Japanese also display the highest frequency of haplogroup O3a5, which is a Han Chinese and Sino-Tibetan specific O3 branch.
Xue et. al.
Japanese
Haplogroup O3a5 (O3e) 10/47= 23%
This frequency is about 5% higher than the frequency of O3a5 among Manchus, Koreans and other Northeast Asians.
For North Koreans, the frequency of O3a5 is even lower than some Tungusic populations. Overall, the Koreanic haplogroup O3 were the least influenced by Sinitic populations.
Whereas pure haplogroup C3 (M217-no subclade) was observed at a high frequency among Tungusic (20%) and Koreanic (16%) populations. The frequency of haplogroup C3 among Japanese was only 1%. This means Japanese origins were NOT from Siberia.
Haplogroup D was observed among Japanese (25%) and Tibetans (40%). Was also observed among Han Chinese, Mongolians and Koreans.
DNA sequence SNP study done by Japanese researchers in 2005.
Biggest contributor of DNA of each East Asian people is bolded
Korean DNA sequence is made up of:
40.6% Uniquely Korean
21.9% Chinese
1.6% Ainu
17.4% Okinawan
18.5% Unidentified
Japanese DNA sequence is made up of:
4.8% Uniquely Japanese
24.2% Korean
25.8% Chinese
8.1% Ainu
16.1% Okinawan
21% Unidentified
Chinese DNA sequence is made up of:
60.6% Uniquely Chinese
1.5% Japanese
10.6% Korean
1.5% Ainu
10.6% Okinawan
15.2% Unidentified
The biggest components in Japanese are Chinese, Korean, Okinawan.
It's a fact that Korean peninsula was not as isolated as Japanese islands. But, this meant one people could settle on the peninsula, but Japan became an island of migrants. This is maybe why Koreans have the least Japanese and Chinese components, whereas Japanese and Chinese have higher Japanese and Chinese components to their DNA.
Overall, Japanese are closest to Tibetans. And Ainu are divergent from Jomon, as they were influenced by Siberians, just like Koreans. Evidence is the haplogroup C3 (no subclade) occurs at moderately high frequencies among these populations.
it is very interesting.
every thing is solved....for me
the Japanese by method of Mitochondrial DNA
Mitochondrial DNA - Wikipedia
the korean and the Japanese are very simillar...( that is,matrilineal. mother lineage)
( Korean is not south korean. I mean korean who is living southern part of south korea like Pusan or kaya)
korean is more similar with ainu than the Japanese
Y Chromosome father lineage(paternal line)
korean and the Japanese are quite different because of
D(Yap+)
most okinawan and Ainu have D(Yap+)
Why is it so similar by the method of mitochondria, and is it very different by the method of the chromosome?
only women came to Japan as Yayoi? I dont think so

As for the movement in the group, men was more numerous .
How about Latin America?
How about example of the Pacific Ocean islands?
How about India?
After the 16th century, present Latin American nations were conquered by Spain and Portugal. It is chiefly men that came.
As a result, there are a lot of Y chromosomes of the Caucasian lineage in Latin American nations.
However,The Caucasian origin is few by mitochondria method
most of type is native ppl'
so are polynasia, Guam....
Aryan (one race of Caucasian) invaded India from Central Asia 3000 years or more ago, and the upper layer hierarchy was formed for India.
As a result, there are many patrilineal more than the matrilineal...
accoding to descendant Genghis Khan Research
the Y chromosome goes over the cultural barrier by the occupation of the short term of around 100 and does not spread..
The ruler should be in the top in the society until race's uniting for long long time.
Top management in the ancient society of which the Jomon people fused with Yayoi shows that the Jomon was farther more than Yayoi.
In short, the Jomon people conquered the people village of Yayoi where it had emigrated with high probability
Small number of people comparatively people who made the Jomon people an ancestor were in top management in the society, and people of a lot of yayoi were ruled.
The pattern excluding this is impossible.
so is language.
The mark of an ancient Korean language is not seen at all in Japan.
