Answer:
Great Britain
Explanation:
Up until 1941, the only country fighting the Nazis was Great Britain. France and Belgium were sadly occupied by the Nazis during this time.
Japan, on the other hand, was not directly involved in the war against the Nazis until later in 1941 when they attacked the United States at Pearl Harbor. But it's important to note that there were also resistance movements and individuals fighting against the Nazis in various occupied countries.
Hope this helps!
