There were about 90 different Air Groups in the Japanese Navy Air Force. These were known as Kokutai's. These Air Groups were either assigned Names or Numbers. (The Japanese Army Air Force referred to their Air Groups as Sentai's.)

The Named Air Groups were linked to either a particular air command or an air base in Japan. When the Air Groups left Japan they were usually issued with an Air Group number. e.g. the Kanoya Air Group became the 253rd Air Group.

  • Air Group Type of

Number Aircraft

  • 200 - 399 Fighter Groups
  • 400 - 499 Float Planes
  • 600 - 699 A mixture of aircraft

Air Groups were usually divided into 3 or 4 squadrons or Hikotai's. A Squadron based on an aircraft carrier or other vessel usually had the name of the aircraft carrier assigned to their squadron name. A squadron normally comprised 12 to 16 aircraft commanded by either a junior Lieutenant or Warrant Officer or experienced Chief Petty Officer. Most pilots were non commissioned officers.

There were usually 4 Flights or Sections (Shotai's) of between 3to 4 aircraft in each Squadron. By 1944 it was normal for a Flight to comprise 4 aircraft.
