Background

After
Giretsu operations were to be undertaken at night, beginning with air strikes by bombers. After this, commando units would be inserted onto the target airfield by crash landing their transports. The fact that there was no provision for extraction of the strike force, along with the rejection of surrender in Japanese military doctrine at the time, meant that the Giretsu ground operations were effectively suicide attacks.
The attack against the Marianas was scheduled for December 24, 1944, but was called off after American raids damaged the planned refueling airfields on Iwo Jima. After the Marianas raid was cancelled plans were made to attack airfields on Iwo Jima captured by the United States Marine Corps in March, but these too were cancelled when the Iwo Jima garrison fell.

By the end of April the TAF had two Marine Aircraft Groups ashore giving it six F4U Corsair squadrons and two night fighter squadrons equipped with Grumman F6F Hellcats[12][14] TAF initially maintained a CAP of 12 aircraft overhead however as the kamikaze threat grew it increased to 32 aircraft overhead with an additional 12 aircraft on ground alert.[15] For the month, TAF aircraft flew 3,521 combat air patrols sorties and were responsible for assisting in the shooting down of 143 enemy aircraft.[16]

Preparation and Organization
The Japanese Sixth Air Army began preparations for the attack in early May. Led by Captain Okuyama, the raid force moved from Nishitsukuba to Kumamoto as it continued to prepare for the assault. Aircraft for the raid came from the Third Independent Air Unit based in the vicinity of Hamamatsu. The raid force consisted of 120 commandos broken up into a headquarters section and five flights, each containing twenty men. They were to be transported by twelve Mitsubishi Ki-21s stripped of their guns and with additional forward and rear exits added to assist raiders with exiting.[17] The timing of the raid was also meant to coincide with the withdrawal of Lieutenant General Mitsuru Ushijima's 32nd Army from the Shuri Line in southern Okinawa.[18]
On May 18, Imperial Japanese Army headquarters approved the operation and issued orders for it to take place on May 23. The raid was to precede as part of Operation Kikusui VII, one of a number of large Kamikaze attacks flown against US forces in the vicinity of Okinawa. Operations on May 23 were cancelled due to poor weather in the vicinity of the target airfield.[19]
Execution of Raid
Twelve Japanese bombers departed from an airfield near Kengun, Japan on the evening of May 24 with 136 commandos aboard. The flight to Okinawa would take 4 hours. Each plane had its flight crew and 12 commandoes aboard. Shortly after take-off, four planes developed engine trouble and returned to base. Three more of the bombers were successfully intercepted by American night fighters while en route to Okinawa.[3]

Just after 8pm on May 24, Japanese bombers began to strike targets at both Ie Shima and Yontan Airfields. At 2225 the first of the remaining Giretsu Sally bomber approached Yontan Airfield at very low level and was successfully engaged by Marine anti-aircraft gunners of the 1st Provisional Antiaircraft Artillery Group who were tasked with defending the field.[21][22] Five minutes later, three more Japanese aircraft appeared at low-level over Yontan and were observed attempting to land before being shot down or crash landing. A small number of Giretsu survived this wave and began their mission of attacking aircraft on the airfield.[3] A fourth aircraft was shot down south of the airfield and its severed wing fell and hit an anti-aircraft position killing two Marines from the 16th Antiaircraft Artillery Battalion.[20] A fifth aircraft successfully evaded anti-aircraft fire and was able to belly land approximately 100 meters from the control tower.[3] Immediately upon landing, approximately 10-12 commandos were able to disembark and begin their assigned mission of destroying aircraft on the airfield.[23] The attackers flung grenades and attached incendiary devices to aircraft as chaos initially reigned amongst large numbers of aircraft maintenance and airfield services personnel in the vicinity.[24]
Among the first to engage the Japanese attackers was 1stLt Maynard Kelly who was working in the Yontan air traffic control tower that evening. Eventually, led by 1stLt Clark C. Campbell and Technical Sergeant Chandler M. Beasley from VMF(N)-542, the Marines on the field were able to organize a disciplined resistance and begin to engage the remaining Japanese commandos.[24] Fighting continued throughout the night into the early morning. The last of the Japanese attackers was killed at 1255 on May 25 about a quarter of a mile behind Marine Aircraft Group 31's headquarters building.[25] After the raid, two Marines from the 8th Antiaircraft Artillery Battalion discovered a Japanese officer sleeping in the jungle near the airfield and shot him in the head for which they were court-martialed.[25] One member of the raiding party survived and was able to make his way across the battlefield, reaching the Thirty-Second Army Headquarters (Okinawa) around June 12.[26]

Aftermath
Operation Kikusui VII, another large kamikaze raid which ran in conjunction with the raid on Yontan, took place between May 23–25. It consisted of 387 Navy planes and 174 Army planes (of which 107 Navy planes and 61 Army planes were kamikazes). The achievements of this raid were quite small compared to the previous operations, with only 1 transport sunk and 1 escort aircraft carrier damaged.
For his actions during the attack, 1stLt Maynard C. Kelley was posthumously awarded the
The Japanese considered the Yontan Raid a success so a second large-scale "giretsu" attack was planned with the objective being American bases in the Marianas. The specific intent of this follow on raid was to destroy B-29 Superfortress bombers that were bombing the Japanese mainland. This second raid was to be much larger than the first with 60 transports and 900 commandos planned for the nights of 19–23 August 1945 (Operation Ken-gou). On August 15, Japan surrendered and the operation was canceled.[3]
