Kamikaze

Also known as: Divine Wind · Shinpu Tokubetsu Kogekitai · Tokkotai · Tokko

Definition

Kamikaze (Japanese: 神風, “divine wind”) was the World War II tactic of deliberately crashing explosive-laden aircraft into Allied ships, first organized by the Imperial Japanese Navy in the Philippines in October 1944 as conventional air power collapsed. The units’ official name was Shinpū Tokubetsu Kōgekitai — “Divine Wind Special Attack Unit,” the same characters read “kamikaze” — recalling the typhoons that dispersed Kublai Khan’s invasion fleets in 1274 and 1281; the generic term was tokubetsu kōgekitai, abbreviated tokkōtai or tokkō. (Wikipedia, Wiktionary)

The tactic entered the war over Philippine waters. At Mabalacat Airfield near Manila on October 19, 1944, Vice Admiral Takijirō Ōnishi, commanding the First Air Fleet, told officers of the 201st Flying Group that crashing a Zero with a 250-kilogram bomb into an American carrier was the only certain method left; on October 25, 1944 — the day of the Battle off Samar — the first organized strikes flew, and the escort carrier USS St. Lo became the first major warship sunk by a kamikaze, struck at 10:51 and destroyed by magazine explosions half an hour later. (Wikipedia, Wikipedia — USS St. Lo) From Leyte Gulf through Lingayen Gulf to Okinawa, roughly 3,800 pilots died in the attacks, killing more than 7,000 Allied naval personnel; about 19 percent of attacks succeeded, sinking some 45 ships — none larger than an escort carrier — and altering no campaign’s outcome.

Examples and Analogies

A manned missile: a kamikaze sortie was a bomb given a pilot — the aircraft aimed as a weapon rather than a weapon delivered by an aircraft — which is why the United States Navy has called the tactic a precursor of the modern cruise missile; purpose-built successors like the rocket-powered Yokosuka MXY-7 Ohka (“Baka” to the Americans), deployed from March 1945, completed the logic as a piloted flying bomb. (Wikipedia)
The twenty-fourth volunteer: at Mabalacat, Commander Asaichi Tamai asked 23 student pilots to volunteer and all raised both hands; Lieutenant Yukio Seki, chosen as the 24th, reportedly said he would go “because I was ordered to” — the compact between enthusiasm and command the whole program reproduced. (Wikipedia)
One hit, one carrier: St. Lo’s fate showed the physics — a single smoking Zero, diverted from USS White Plains, banked into the escort carrier at 10:51; its bomb detonated on the hangar deck among fueled aircraft, and the ship was gone within about thirty minutes with 113 of her 889 men killed or missing. (Wikipedia — USS St. Lo)

Usage Scenarios

1. Studying the Battle of Leyte Gulf

Historians treat October 25, 1944 — the dual-origin first day on which pre-planned strikes from Davao opened against Taffy 1 at 07:40 while Ōnishi’s Luzon-based units sank St. Lo — as the kamikaze’s point of entry into the war, the moment this wiki’s Battle off Samar and Battle of Leyte Gulf entries record as the start of the suicide-attack era. (Wikipedia, Wikipedia — USS St. Lo)

2. Tracing the Liberation Campaign of 1944–1945

Researchers of the Philippine liberation follow the tactic’s escalation through the archipelago — from Leyte Gulf in October 1944 to the December 1944–January 1945 strikes that climaxed at Lingayen Gulf, where kamikazes were the decisive naval threat to the Luzon landings and Japan ended the Philippine fighting having “expended every aircraft” it had in the islands. (Wikipedia — Battle of Lingayen Gulf)

3. Analyzing Anti-Air and Damage-Control Doctrine

Naval analysts credit the weapon with forcing the countermeasures of 1945 — dispersed formations, radar pickets, combat air patrols, massed anti-aircraft fire — and the damage-control lessons of hangar-deck fires among fueled aircraft, the failure sequence that destroyed St. Lo. (Wikipedia, Wikipedia — USS St. Lo)

4. Linguistic and Ethical Study

Scholars of language trace the word’s journey — from the 1281 typhoon, through the special attack units, to a postwar English noun for any suicidal act — a case study in how a military tactic becomes a metaphor. (Wiktionary, ConceptNet)

Strategies

Certainty traded for scale: Ōnishi’s rationale — that conventional attack’s hit probability had fallen so far that only the crash was sure — made each sortie reliable (about 19 percent hit) while consuming pilots Japan could not replace, the trade the whole program ran on. (Wikipedia)
Mass over accuracy: at Okinawa from April 6, 1945, Operation Kikusui saturated defenses with massed waves — 30 or more US warships sunk or knocked out in the first effort, at the cost of 1,465 aircraft. (Wikipedia)
Escort and diversion: first-day tactics paired the suicide aircraft with escorting aces and exploited smoke and simultaneous multi-direction dives to defeat concentrated gunfire. (Wikipedia)
For researchers: carry the precise claims — St. Lo was the first major warship sunk by a kamikaze; HMAS Australia had been blooded by a possibly unorganized crash on October 21, 1944; the day’s first organized strikes hit Taffy 1 — and avoid “first kamikaze attack,” which names no single event. (Wikipedia, Wikipedia — USS St. Lo)

Security and Safety Measures

The fleet’s answer — density and distance: combat air patrols, radar picket destroyers, and massed anti-aircraft barrages (“the big blue blanket”) were the standing countermeasures, designed to break up raids before the final dive. (Wikipedia)
Hangar-deck discipline: St. Lo was lost because the strike found fueled and rearmed aircraft below decks; the doctrine that followed treated fueling and rearming cycles and magazine flooding as life-or-death timing decisions, not housekeeping. (Wikipedia — USS St. Lo)
Rescue and survival drill: the survival of more than three-quarters of St. Lo’s crew, pulled from the water by consorts within minutes, reflected the screen’s rescue discipline, repeated across the kamikaze war’s casualty lists. (Wikipedia — USS St. Lo)
War graves: ships sunk by kamikazes in Philippine waters, from St. Lo off Samar to Ommaney Bay in the Sulu Sea, rest with their dead and are treated as protected war graves rather than dive sites. (Wikipedia — USS Ommaney Bay)
Source discipline: survivor testimony still revises details — even St. Lo’s pilot is stated only as “perhaps” Lieutenant Seki — so claims should carry the standard account’s own qualifications. (Wikipedia — USS St. Lo)

Historical Context

The name reached back seven centuries: the typhoons of 1274 and 1281 that wrecked Mongol invasion fleets were remembered as divine winds protecting Japan, and the weapon’s designers borrowed the story’s sanctity for units whose title, Divine Wind Special Attack Unit, classical poetry reinforced in the subunits’ names. The decision was born of desperation in the Philippines: after American carrier raids destroyed Japanese air strength, Ōnishi — taking command of the First Air Fleet as the Leyte landings of October 20, 1944 opened the campaign — concluded that skill-based attack could no longer reach the enemy’s carriers, and on October 19 at Mabalacat assembled the volunteers whose first mission flew five days later. (Wikipedia)

The Philippine record then set the pattern. On October 25, 1944 the first organized strikes hit the escort carriers covering the Leyte beachhead — opening against Taffy 1 at 07:40, as this wiki’s Battle off Samar entry records, while Seki’s Shikishima unit fell on Taffy 3 around 10:50 and sank St. Lo in the same hour the gun battle off Samar ended. The escort carrier group lost Ommaney Bay in the Sulu Sea on January 4, 1945, and at Lingayen Gulf, January 3–13, 1945, roughly a hundred or more attackers hit about 47 ships and killed some 738 shipboard personnel, wounding 1,282, in the tactic’s greatest concentration against a single landing — a British general died on New Mexico’s bridge and an American rear admiral of wounds from Louisville’s strike. At Okinawa, Kikusui mass attacks knocked the fleet carriers Franklin, Bunker Hill, and Enterprise out of the war, and the destroyer Callaghan, sunk July 29, 1945, was the last major victim; last attacks were recorded on August 20, 1945. The assessment stands as the surveys left it: about 45 ships sunk, none larger than an escort carrier, at the cost of thousands of pilots — a weapon that could not turn the tide it was invented to turn.

Challenges and Controversies

The “First Attack” Question

Accounts differ on which strike of October 25, 1944 deserves the designation “first” — the pre-planned attacks from Davao that opened on Taffy 1 at 07:40, or Ōnishi’s Luzon units that sank St. Lo — and earlier unorganized crashes (HMAS Australia, October 21, 1944, which killed her captain) complicate any simple origin story; the settled facts, as this wiki’s Leyte Gulf entry also concludes, are the date and the first ship sunk. (Wikipedia, Wikipedia — USS St. Lo)

Strategic Assessment

The evaluations diverge on emphasis, not arithmetic: the U.S. Strategic Bombing Survey counted 2,550 sorties and 475 hits for 18.6 percent effectiveness, Air Force analyses credit about 2,800 attackers with 34 ships sunk and 368 damaged, and Bill Gordon’s 2007 compilation lists 47 ships sunk — but every accounting ends with the same verdict, that the attacks delayed operations and killed thousands without saving Leyte, Luzon, or Okinawa. (Wikipedia)

The Volunteer Question

The program’s volunteer framing — all 23 student pilots raising both hands at Mabalacat, Seki going “because I was ordered to” — sits against the documented social pressure of the era, and the historiography and survivor memoirs continue to argue over how much choice the pilots had; the primary record preserves both the volunteers’ assent and the commanding officers’ misgivings without resolving them.
