What are the migration directions of Japan and Russia respectively?

Ten thousand years ago, Japanese aborigines were Japanese, and they were distributed all over Japan.

About 10,000 years ago, Chinese mainland people immigrated to Japan one after another. These immigrants claim to be harmonious. They have been driving the Japanese north. 300 years ago, these Japanese were only distributed in the northern part of Honshu Island and Hokkaido, and were called "Xiayi", so Hokkaido was also called "Shrimp Road". There are very few shrimps in Hokkaido so far. He nationality is basically distributed in all parts of Japan.

About 300 years ago, Japanese Kazuo people migrated abroad, mainly distributed in Hokkaido in the north, Nanyang in the south and Chinese mainland in the west.

Around the Republic of China, Japan immigrated to Korea, Northeast China, North China and Southeast Asia in a planned and step-by-step manner. By the end of World War II, there were millions of ethnic immigrants in these areas, most of whom were repatriated to Japan.

Russia was still a small country in the Song Dynasty. During the divided feudal period (similar to the Yanhuang period in China), the eastern European plain practiced rotation farming, which was similar to nomadic farming civilization. After Mongolia annexed Russia, it established puppets to fight for it, and introduced the advanced culture learned from China into Russia, so Russia quickly entered a civilized society. Under the rule of Mongols, it spread to most parts of the eastern European plain.

The puppet regime copied by Russia finally dared to break away from the Mongols. And expand everywhere. First annexed Lithuania and other countries to the west, and then occupied the lower reaches of the Volga River to the south. At the end of Ming Dynasty, Russia seized the opportunity of Manchuria Uprising in Northeast China and annexed the whole of North Asia.

After the demise of the Ming Dynasty, Russia continued to expand westward;

Expand eastward to the north of Sakhalin Island, cross the Bering Strait, and occupy Alaska.

To the south, it cut off large areas of Turkey and Iran, controlled the whole Caucasus and annexed Central Asian countries. Its sphere of influence extends to the north of the Great Wall and the whole of Iran.

Divide Poland and merge Finland into Prussia and Austria in the west.

It has always controlled most of the northern Arctic Ocean.

Although Russia has large areas that it can't conquer, its ability to immigrate to these areas is limited. Even now, there are only 20 to 30 million Russians in North Asia, far less than in Heilongjiang Province.

Recently, the Soviet Union disintegrated, Russia weakened, and the Russian population in Central Asia and North Asia continued to decline.
