The unit was formed on 10 February 1942 by combining one division (buntai) from Chitose Air Group that was previously stationed in the Central Pacific, and two divisions from Takao Air Group that participated in the conquest of the Philippines and Dutch East Indies. They operated the new Mitsubishi G4M "Rikko" Navy Type 1 Attack Bomber aircraft. That same month, the group was deployed to Rabaul, New Britain to support Japanese operations during the early stages of the New Guinea Campaign, at first as part of the 24th Air Flotilla and from April as part of the 25th Air Flotilla.
