The British, French, and Japanese had large empires, and they had both similarities and differences when ti came to their policies.
Step-by-step explanation:
The British has the largest empire in the human history. Their imperialism was of mixed type. They had some colonies where they settled large masses of people, but also had some where they didn't do this. The British exploited the colonies but also invested in them, and even giving certain autonomy to some.
The French too had a vast empire stretching on several continents. Unlike he British though, the French had policy to not settle in people. Instead, the French tried to make allies of the people in their colonies and collaborate with them so that they can benefit economically. Another characteristic is that they didn't invested in their colonies.
The Japanese empire was in East Asia, Southeast Asia and the western Pacific. The Japanese were very cruel rulers. Not just that they tried to fully exploit the natural resources of their colonies, they were brutal toward the population. Experiments were done on live humans for development of biochemical weapons. The women were abused in millions n order to change the demographic picture. Lot of people were slathered without any particular reason for such actions.
