Was the Japanese attack on Pearl Harbor a success or failure from the Japanese point of view? Explain.

From the Japanese point of view, the attack on Pearl Harbor was a success in the sense that it achieved surprise and inflicted significant material damage on the U.S. Pacific Fleet. However, it was ultimately a failure because the U.S. forces recovered and managed to remain in the war, eventually defeating Japan. This invalidated the majority of the war plan designed around the attack on Pearl Harbor.
