All Japan immigrated to Brazil.

As far as I know, Japan began to immigrate to Brazil a long time ago. At first, because the people at the bottom of Japan were poor and could not live a normal life in Japan, they had to emigrate. Especially when Japan launched a large-scale war of foreign aggression, the people at the bottom of Japan were miserable and had to move to other countries to protect their lives. So Brazil may be the best choice in the eyes of the Japanese.

In fact, in the early 20th century, Japan began to immigrate to Brazil in large numbers. At that time, the people at the bottom of Japan were too poor to live normally in Japan. As a paradise, there is no war in Brazil, and a large number of civilians began to immigrate to Brazil. After the Meiji Restoration in Japan, with the rapid development of domestic capitalism and the enhancement of military strength, the bottom farmers in Japan began to become extremely poor and even bankrupt.

When there was no war in Brazil, Japanese civilians could not live a normal life. Brazil was in the stage of economic development and needed a lot of labor, so the Japanese went to Brazil in large numbers to survive. Japan's small territory, lack of resources, unable to survive the Japanese forced to live overseas, seeking survival. At that time, Brazil was in the stage of economic development, and many places in Brazil were growing coffee on a large scale, which required a lot of labor.

From this perspective, there are so many Japanese in Brazil, which is the result of a large number of Japanese immigrants. In fact, it was all due to Japan's foreign aggression at that time. Originally, the people at the bottom of their own country had a bad life and were allowed to display weapons and equipment that they could not produce, regardless of the lives of the civilians at the bottom. Therefore, a large number of low-class civilians have to go to other countries to seek a way to survive.
