Pearl Harbor is a lagoon harbor on the island of Oahu, Hawaii, west of Honolulu. It's been long visited by the Naval fleet of the United States, and it's the headquarters of the United States Pacific Fleet. This is the site of the attack on Pearl Harbor by the Empire of Japan on December 7, 1941, which was the immediate cause of the United States' entry into World War II.
