An investigation of global policy with the Yamato race as the nucleus is when a group of people, usually scientists and experts, study how people of the Yamato race—who are a part of the race of people living in Japan—are affected by various laws and policies around the world. They look into how people are treated and what kind of impact different laws and policies have on the lives of people in the Yamato race and their culture. They also study how this impacts people of other races and cultures, too.
