A negative changes what you must select.
This question does not ask for a correct name from the group of four; it asks for the exception. Selecting the USA identifies a real occupation power but overlooks the negative wording.
Japan was involved in the war, but on a different side from the four occupation powers in Germany. The Tripartite Pact joined Japan, Italy and the German Reich. Japan’s surrender was signed on 2 September 1945.

The other three answers
The other three choices are incorrect precisely because they were real occupation powers.
USA
The USA administered one of the four occupation zones. It is not an exception to the group.
Soviet Union
The Soviet Union administered the Soviet occupation zone. It explicitly belongs to the four Allied occupation powers.
France
France was also one of the four occupation powers and had its own occupation zone.
“Allied” depends on historical context.
In general language, any states in an alliance can be called “allied”. Here, however, “Allied occupation powers” identifies the specific four powers in Germany after 1945. Japan’s alliance with Germany does not make it one of those powers.
The answer does not judge Japan’s population today or current relations between states. It identifies a historical role after World War II.
