Previously documented genetic contributions were confirmed from two ancient groups. The first was Japan’s indigenous culture of hunter-gatherers dating to roughly 15,000 years ago, the start of what is called the Jomon Period. The second was a population of Northeast Asian origins who arrived at about 900 BC, bringing wet-rice farming during the subsequent Yayoi Period.

Modern Japanese possess approximately 13% and 16% genetic ancestry from those two groups, respectively, the researchers determined.

But 71% of their ancestry was found to come from a third ancient population with East Asian origins that arrived at roughly 300 AD.

These migrants appear to have had ancestry mainly resembling the Han people who make up most of China’s population.

At precisely this period Japan also suddenly got writing and its architecture/cultural traits, which all happen to closely resemble Chinese culture. i.e the islands were colonized by Chinese settlers. The aboriginal natives were exterminated/bred out.

Japan is rightful Chinese clay.

And even with all those genetic similarities, you will have a hard time finding two groups of people who hate each other more than these two. If one wants to point fingers, if would be easy to point to the Japanese as the villans of this story but life is always more complicated than that.

Genetics means nothing compared to social and cultural elements, Igor. I imagine that most people in the former Republics of Yugoslavia have very similar genetic background, what difference did that make?

Remove foreign influences and we're best friends. We call all croats/serbs/bosniaks 'nasi' or 'our people' when abroad. It's all foreign imported animosity propped up by foreign empires. Division and conquest. Bosnia and Croatia are now controlled by Brussels. Serbia remains independent.

There was a major influx of Han Chinese migrants from mainland China during the Kofun period from the 3rd to the 7th centuries. One Kofun sample from the period (KOFUN) carried Y-DNA haplogroup O3a2, which is a major Han lineage, covering 35% of the Han Chinese population today. However, the frequency of this Chinese haplogroup is 19%-24% in the modern Japanese population, while the Jomon D1b lineage makes up 25%-55% in Japanese males. The study probably overestimated the demographic impact of the Han migration due to its limitations, thus underestimating the Jomon genetic heritage.

Our initial screening focused on 14 ancient skeletal remains excavated from six archaeological sites across the archipelago (see note S1). High levels of endogenous human DNA were preserved in 12 of these samples (Table 1), which were then further shotgun-sequenced to higher coverage, ranging from 0.88× to 7.51× (Fig. 1 and table S1). Nine of the 12 samples are associated with the Jomon culture, representing the west and central parts of the archipelago and four different stages of the Jomon period (Initial, Early, Middle, and Late Jomon) (Fig. 1). The remaining three samples date to ~1.3 ka ago, falling within the Kofun period. We confirm that all newly sequenced genomes show postmortem damage patterns (fig. S1) and a low level of modern human contamination (<2.15%) (Table 1 and table S2). Our kinship analysis confirms that all pairs of individuals are unrelated (fig. S2). Mitochondrial haplogroups for all Jomon individuals belong to the N9b or M7a clades, which are strongly associated with this population (11–14, 22) and rare outside of Japan today (23). The three Jomon males (table S3) belong to the Y chromosome haplogroup D1b1, which is present in modern Japanese populations but almost absent in other East Asians (24). In contrast, the Kofun individuals all belong to mitochondrial haplogroups that are common in present-day East Asians (25), while the single Kofun male has the O3a2c Y chromosome haplogroup, which is also found throughout East Asia, particularly in mainland China (26).

But 71% of their ancestry was found to come from a third ancient population with East Asian origins that arrived at roughly 300 AD to launch what is called the Kofun Period, bringing various cultural advances and developing centralized leadership. These migrants appear to have had ancestry mainly resembling the Han people who make up most of China’s population.


Is that a resemblance in the same way Wikipedia https://en.wikipedia.org/wiki/Genetic_h ... ast_Asians says East Asians and sometimes claims SEA are closely related to Han?
No comment on relations to Korean?

The Japanese originated from probably a roughly 50/50 mix, one from an ancient and in some ways more primitive human group that once inhabited Lake Baikal (Siberia) all the way towards Sakhalin Island (located just North of Hokkaido), and the other from the Southern Chinese coastal region of Zhejiang. The Ainu (of Northern Japan) descend mainly descend from the first group. This is a strange group, they have lighter color skin, almost a little bit Caucasian facial features and thicker Northern European-like hair, but they probably are closest related to the "Negrito" group, which is the Black people who once lived all across South Asia, and perhaps even in China in extremely ancient prehistoric times even before the Mongoloid peoples, who were the ancestors of the Chinese, migrated there from further north in Asia. These Black people are closest related to the Australian aborigines and the Andaman Islanders off the coast of India. I think I can see some of those "Black" facial features, just a little bit, in the appearance of the Ainu, with their nose shape.

It sounds crazy, but this is the best I have been able to put together from all the pieces and trying to look the DNA evidence.

It is believed that both groups began populating Japan, one from the north and the other from the south, at the same time.

I am far from an expert in this, but living in China for many years, know that Japanese uses three different written scripts and one is basically Chinese. If it’s Chinese, I can recognize it in Japan even though the Japanese word is different obviously than the Chinese (普通话) word.

One example is being in Tokyo trying to catch a taxi. An empty taxi with have a light that says “空车” which means “empty car” or taxi available. Same in Osaka or Shanghai. The character for alcohol is 酒。爱 is “love”. There are many more I am sure.

Sort of make sense that the ancient Japanese people came from China and Korea and came across to the island in antiquity. Mongols and Chinese. The old Mongolian empire under Genghis Khan and there after tried to take over Japan but conditions made it impossible for them to do so.

The old 1970’s show Barney Miller had a scene where Dietrich the resident genius tell Yemana the Japanese/American cop that basically his people came from
China. So it’s fairly common knowledge.

The Japanese arrived in three waves.
A theory is now widely accepted in Japan that there are two types of ethnic subtypes, Jomon and Yayoi.
https://factsanddetails.com/japan/cat16 ... -5284.html

The Jomon probably populated Japan first and came from the South, the coast of China. Today the Jomon-type is more common in Japan's Southernmost islands such as Okinawa. Later another group of peoples came from the Korean peninsula, named the Yayoi. This group overwhelmed the original Jomon population in central Japan, which became the heart of Japanese civilization. These are ancestors of the population that inhabited Southern Korea at that time. The population that inhabits Korea today descend in part from this group but more from population who came from what was at that time further North.

In my view, it's possible that the Ainu originated from a mixture of the original Jomon, and the people who came from Siberia. Before the Yayoi came who would form the backbone of the mainstream modern Japanese civilization.

The Jomon were probably a little more Polynesian and Austronesian type, perhaps somewhat ethnically related to modern Cambodians, inhabiting the coast of southern China in very ancient times. The traditional ethnic group in the Cantonese region of China seems like it might consist of a partial mix of this type.

discussing theory on the origins of the Japanese language:
"An increasingly popular theory along that line posits that the mixed nature of Japanese results from its Austronesian lexical substratum and the Altaic grammatical superstratum. According to one version of that hypothesis, a language of southern origin with a phonological system like those of Austronesian languages was spoken in Japan during the prehistoric Jōmon era (c. 10,500 to c. 300 BCE). As the Yayoi culture was introduced to Japan from the Asian continent about 300 BCE, a language of southern Korea began to spread eastward from the southern island of Kyushu along with that culture, which also introduced to Japan iron and bronze implements and the cultivation of rice. Because the migration from Korea did not take place on a large scale, the new language did not eradicate certain older lexical items, though it was able to change the grammatical structure of the existing language. Thus, that theory maintains, Japanese must be said to be genetically related to Korean (and perhaps ultimately to Altaic languages), though it contains Austronesian lexical residues. The Altaic theory, however, is not widely accepted."

Some genetic comparisons have shown that Japanese are most closely related (40-45%) to Neolithic Northern Chinese Yellow River populations. This probably would have come through the Korean peninsula, since the population living in Southern Korea at that time was probably more closely related to the Chinese Yellow River population (which was the original ancestry of the Chinese civilization).

Baloney.

After the Soviet Union fell, Yugoslavia got into financial trouble. At that point, ethnic conflict returned. It didn't disappear, it was simply repressed.

The other matter is your OP is nuts.

Japan is wealthier and more advanced than China. That they share some genetics is not an argument to let China screw them up as badly as the Chinese government has screwed up China.

Beyond that, Japan is xenophobic. They correctly perceive China as an enemy, not as part of their family.
