The Imperial Japanese Navy fielded naval paratroopers during World War II.
 The troops were officially part of the Special Naval Landing Forces (SNLF or "Rikusentai").
 They came from the 1st, 2nd and 3rd Yokosuka SNLFs.
 The 2nd Yokosuka took no part in any airborne operations and became an island defensive base unit.
 They were under the operational control of the Imperial Japanese Navy Air Service (IJNAS or "Dai-Nippon Teikoku Kaigun Koku Hombu").
 "Rikusentai" paratroopers should not be confused with the Imperial Japanese Army paratroopers, known as "Teishin".
The Yokosuka B4Y, (Navy Type 96 Carrier Attack Bomber), carrier torpedo bomber was used by the Imperial Japanese Navy Air Service from 1936 to 1943.
 The B4Y replaced the Mitsubishi B2M2 and was the last biplane bomber used operationally by the Imperial Japanese Navy.
 The Allied reporting name was "Jean".
Captain Eikichi Kato was a senior officer in the Imperial Japanese Navy during World War II.
 Kato was the senior officer of the Imperial Japanese Navy forces on the Bonis Peninsula and Buka Island during the latter stages of World War II.
A Kōkūtai (航空隊 ) was, during World War II and in the Imperial Japanese Navy, a type of aerial combat unit, similar to the Air Groups in service in the other armies and navies of the time (called "Group" in the British Royal Air Force, "Gruppe" in the German Luftwaffe, "Groupe" in the French Armée de l'Air etc.).
 Although belonging to the Imperial Navy the Japanese Kōkūtai could be based at land or on board naval aircraft carriers and were constituted by hundreds of men and aircraft (that latters were distributed in smaller units called Hikōtai, the equivalent of squadrons).
 For example, the famous 343 Kōkūtai (a fighter group, divided in three Hikōtai) was based at land while the 652nd Kōkūtai (a bomber group) was carrier-based.
 As in general in the Imperial Japanese Navy Air Service, most pilots and aircrew members of a Kōkūtai were non-commissioned officers.
The bombing of Chongqing (, Japanese: 重慶爆撃 , from 18 February 1938 to 23 August 1943) was part of a terror bombing operation conducted by the Imperial Japanese Army Air Service and Imperial Japanese Navy Air Service on the Chinese provisional capital of Chongqing, authorized by the Imperial General Headquarters.
