How did japan justify its conquest of neighboring territory during world war ii?

The appropriate response is Ethnocentrism, drive out European colonialism. Unmistakably the essential main impetus for the Imperialism in Europe was ethnocentrism and not the prudent advantages the Europeans were making. Ethnocentrism is judging another culture exclusively by the qualities and measures of one's own way of life. Ethnocentric people judge different gatherings in respect to their own ethnic gathering or culture, particularly with worry for dialect, conduct, traditions, and religion.
