First Carrier Division
was an aircraft carrier unit of the Imperial Japanese Navy's First Air Fleet. At the beginning of the Pacific Campaign of World War II, the First Carrier Division consisted of the fleet carriers "Akagi" and "Kaga". The division participated in the Attack on Pearl Harbor and Indian Ocean Raid. After "Akagi" and "Kaga" were sunk at the Battle of Midway in June 1942, carriers "Shōkaku", "Zuikaku", and "Zuihō" were redesignated as the First Carrier Division.
