The Japanese justified their imperialism in multiple different ways, depending on what territory is in question.
For China, there was a fake attack on Japanese property, performed by the Japanese themselves, so they invaded Manchuria with the justification that their citizens were in danger.
Korea and Taiwan were justified in the sense that some countries had colonies which they used for resources and as market for their products, so the Japanese justified it in the manner that they also deserve to have such territories.
For some territories they conquered there was no real justification though, and the Japanese didn't really bothered with making excuses anymore.
I think its because the first people who came here were originally close in distance (ie. most people came from England and places near England.) When we brought slaves over, the African people along with the native people to the Americas (the native Americans) had to learn to understand us to make peace, trade, and other stuff.

Dear Friend,
I wish I could stay in town and help the town. I just dont want to get the plague and die like everyone else. If you want to come with me, I am going (Write a place). So if you want to come with me I would be glad to have the company. You know that if we still run now the plague will soon catch up to us where ever we go.
With Love,
(Your Name)
P.S. Hope to see you again.
