What was not an allied power in early war?

In the early stages of World War II, the primary Allied Powers included the United Kingdom, France, and China, along with later additions like the Soviet Union and the United States. However, one notable country that was not part of the Allied Powers initially was Italy, which was aligned with Germany as part of the Axis Powers until it switched sides in 1943. Other countries, such as Japan, were also part of the Axis and not aligned with the Allies during the early war period.
