In the long course of historical development, people from some neighboring countries will come to China to do business or settle down.
Over time, as the population increases, an ethnic minority will be formed and gradually become a part of the Chinese nation, such as Koreans, Russians, Jing, etc. Japan is also our neighbor, so why hasn't the "Japanese nation" or "Yamato" been formed?
This has to start with history.
At the latest in the Qin Dynasty, the Central Plains Dynasty had exchanges with Japan, and the most direct evidence is Xu Fu's eastward crossing.
When it came to the Eastern Han Dynasty, the Japanese slave state also sent tribute, and was given a gold seal by Emperor Guangwu of the Han Dynasty, which later resurfaced in Japan in the 18th century and became an important material evidence of early Sino-Japanese exchanges.
In the Sui and Tang dynasties, with the progress of shipbuilding technology (although there will still be many people capsizing and dying in the sea to feed fish), the Japanese vassal states that admired the Central Plains Dynasty sent students to the Central Plains many times to learn various advanced cultures and systems, and even entered the court as officials.
Of course, we will also send some people to Japan to spread the cultureSuch as the famous Jianzhen six crossings to Japan.
Please note that it was the six crossings that succeeded, which shows that although the navigation technology at that time had improved, it was still not very good.
Because of this, until the modern Industrial Revolution, very few Japanese were able to successfully immigrate to the Central Plains by boat, and they were unable to form a minority.
In modern times, Japan began to carry out organized and premeditated migration.
After the Meiji Restoration, Japan's national strength rose sharply, and it embarked on the road of colonial expansion, and every time it invaded a place, it immigrated a large number of people to the local area, hoping to achieve actual control of a certain place by "mixing sand".
After the Russo-Japanese War in 1905, Japan began to immigrate in large numbers in the northeast of China, and through various incentive policies, ignorant people were encouraged to go to the northeast of China to open up wasteland, so as to implement the purpose of doves occupying magpies' nests.
After the September 18 Incident in 1931, the Japanese army occupied the entire Northeast region, simply stopped pretending, had a showdown, and directly organized a large number of "pioneer groups" to enter the Northeast region of China through immigration.
The sinister idea of Japanese imperialism was to dilute the proportion of the local population through a large number of immigrants, and to achieve the goal of completely controlling the three northeastern provinces through colonial education and other means of assimilation.
According to the statistics of Japan's "Greater East Asia Province", 300,000 immigrants came to Northeast China through the "pioneer group" at that time.
This is only the number of agricultural immigrants, not including the number of Japanese troops, Japanese merchants, and Japanese ** at all levels, if they all add up, the number can really be terrifying.
Fortunately, the wolf ambitions of the Japanese were not realized, and they were defeated and surrendered on August 15, 1945.
At the beginning, some of the immigrants of the "pioneer group" were bewitched by Japanese militarism, and when the Soviet Red Army entered the northeast region, they chose "jade shattering", and some were captured by the Soviet Union and went to Siberia to build railways.
After the end of World War II, our country did not have a good impression of these Japanese expatriates, and it would be good if we were willing to repatriate them back to Japan, so how could we let them stay and let them become a minority?
So from March to September 1946, about 1.4 million Japanese nationals were repatriated.
After the founding of the People's Republic of China, repatriation activities continued, and nearly 100,000 Japanese nationals were identified and repatriated to Japan.
So far, those Japanese who entered our country through the "pioneer group" have basically been repatriated.
Of course, there will be a few Japanese expatriates who are not recognized, some are orphans, and some are incognito and difficult to identify, and the overall number is very small.
In addition, through years of cultural education and life influence, they have long spoken Chinese and integrated into the Chinese nation.
No matter from any point of view, there is no need for the existence of "Japanese" or "Yamato" in Japan.
