1: What are the names of Japanese in foreign countries? What about his son? What about his grandson? 2. Why are so many Japanese concentrated in Central and South America?

If you have adopted a foreign nationality, call it a foreign Japanese, such as a Japanese-American. If you are still Japanese, you are called a Japanese living in a certain country, such as the Japanese living in the United States. Because Japan is sparsely populated and poor at that time, Central and South America was sparsely populated and many places needed to be developed, so many Japanese immigrated to Central and South America.
