The 721st Naval Air Group (第七二一海軍航空隊, Dai Nana-Futa-Hito Kaigun Kōkūtai ) was an aircraft and airbase garrison unit of the Imperial Japanese Navy (IJN) during the Pacific campaign of World War II. This air group was organised for use in suicide attacks. It was otherwise known as the God Thunder Corps (神雷部隊, Jinrai Butai).
Kamikaze, officially Shinpū Tokubetsu Kōgekitai, were a part of the Japanese Special Attack Units of military aviators who flew suicide attacks for the Empire of Japan against Allied naval vessels in the closing stages of the Pacific campaign of World War II, intending to destroy warships more effectively than with conventional air attacks. About 3,800 kamikaze pilots died during the war, and more than 7,000 naval personnel were killed by kamikaze attacks.
The Yokosuka MXY-7Ohka is a purpose-built, rocket-powered human-guided kamikaze attack aircraft employed by Japan against Allied ships towards the end of the Pacific War during World War II. Although extremely fast, the very short range of the Ohka meant that it had to be carried into action as a parasite aircraft by a much larger bomber, which was itself vulnerable to carrier-borne fighters. In action during the Battle of Okinawa in 1945, Ohkas were able to sink or damage some escort vessels and transport ships but no major warships were ever sunk. Improved versions which attempted to overcome the aircraft's shortcomings were developed too late to be deployed. Allied troops referred to the aircraft as "Baka Bombs".
The Yokosuka D4Y Suisei is a two-seat carrier-based dive bomber developed by the Yokosuka Naval Air Technical Arsenal and operated by the Imperial Japanese Navy from 1942 to 1945 during World War II. Development of the aircraft began in 1938. The first D4Y1 was complete in November 1940 and made its maiden flight at Yokosuka the following month.
The Mitsubishi G4M was a twin-engine, land-based medium bomber formerly manufactured by the Mitsubishi Aircraft Company, a part of Mitsubishi Heavy Industries, and operated by the Imperial Japanese Navy from 1940 to 1945. Its official designation is Mitsubishi Navy Type 1 attack bomber and was commonly referred to by Japanese Navy pilots as Hamaki due to the cylindrical shape of its fuselage and its tendency to ignite after a hit. The Allied reporting name was "Betty".
The Nakajima C6NSaiun was a carrier-based reconnaissance aircraft used by the Imperial Japanese Navy Air Service in World War II. Advanced for its time, it was the fastest carrier-based aircraft put into service by Japan during the war. The Allied reporting name was Myrt.
The Imperial Japanese Navy Air Service (IJNAS) was the air arm of the Imperial Japanese Navy (IJN). The organization was responsible for the operation of naval aircraft and the conduct of aerial warfare in the Pacific War.
During World War II, Japanese Special Attack Units, also called shimbu-tai, were specialized units of the Imperial Japanese Navy and Imperial Japanese Army normally used for suicide missions. They included kamikaze aircraft, fukuryu frogmen, and several types of suicide boats and submarines.
The 1st Air Fleet, also known as the Kidō Butai, was a name used for a combined carrier battle group comprising most of the aircraft carriers and carrier air groups of the Imperial Japanese Navy (IJN) during the first eight months of the Pacific War.
Warrant Officer Kenji Yanagiya was a member of the Imperial Japanese Navy's Zero fighter aces who fought the Battle of Solomon Islands in October 1942 – June 1943. He is best known as the only escort fighter pilot of the Yamamoto mission to have survived the war.
During World War II, a series of Japanese air attacks on the Mariana Islands took place between November 1944 and January 1945. These raids targeted United States Army Air Forces (USAAF) bases and sought to disrupt the bombing of Japan by Boeing B-29 Superfortress heavy bombers operating from the islands. The Japanese lost 37 aircraft during this operation, but destroyed 11 B-29s and damaged a further 43. Preparations were also made for commando raids on the bases in early and mid-1945 but these did not go ahead.

The Misawa Air Group was an aircraft and airbase garrison unit of the Imperial Japanese Navy (IJN) during the Pacific campaign of World War II. This article covers first generation, second generation, renamed unit the 705th Air Group, and re-organised unit the 706th Attack Squadron also.
The 343rd Naval Air Group was an aircraft and airbase garrison unit of the Imperial Japanese Navy (IJN) during the Pacific campaign of World War II. Created in late 1944 due to the desperate situation of Japan in the closing stages of the war, the 343rd was composed of the best surviving ace fighter pilots the Imperial Navy had at the time, with Captain Minoru Genda in command. This unit was equipped with the best airplane Japan had left by then, the Kawanishi N1K2-J Shiden-Kai, known as George by the Allies; this aircraft could compete with the best wartime Allied fighters, namely, the F6F Hellcat, the P-51 Mustang and the F4U Corsair.
Hideki Shingō was a fighter pilot officer in the Imperial Japanese Navy (IJN) during World War II. He participated in various battles and campaigns throughout the Pacific War and survived the war.
