How were japan's actions before and during world war two similar to germany's action over the same period

Both countries engaged in the mass killing of innocent people in conquered territories.

Both were many times evolved in highly unethical actions

Explanation:

From the concentration camps to the surprise attacks on Pearl Harbor, Japan wasn't looking so good and German was clearly "the bad guy" during the war. There were very straight up grotesque actions that were committed by those two countries. It is known that from the invasion of China in 1937 to the end of World War II, the Japanese military regime might have murdered near 3,000,000 to over 10,000,000 people.
