The Battle of Okinawa
Battle of Okinawa
(Japanese: 沖縄戦, Hepburn: Okinawa-sen) (Okinawan: 沖縄戦, translit. Uchinaa ikusa), codenamed Operation Iceberg,[19] was a major battle of the Pacific War
Pacific War
fought on the island of Okinawa by United States
United States
Marine and Army forces against the Imperial Japanese Army.[20] The initial invasion of Okinawa on April 1, 1945, was the largest amphibious assault in the Pacific Theater of World War II.[21][22] The 82-day battle lasted from April 1 until June 22, 1945. After a long campaign of island hopping, the Allies were planning to use Okinawa, a large island only 340 mi (550 km) away from mainland Japan, as a base for air operations for the planned invasion of the Japanese home islands. The United States
United States
created the Tenth Army, a cross-branch force consisting of the 7th, 27th, 77th, and 96th infantry divisions of the US Army with the 1st, 2nd, and 6th divisions of the Marine Corps, to fight on the island. The Tenth was unique in that it had its own tactical air force (joint Army-Marine command), and was also supported by combined naval and amphibious forces. The battle has been referred to as the "typhoon of steel" in English, and tetsu no ame ("rain of steel") or tetsu no bōfū ("violent wind of steel") in Japanese.[23][24][25] The nicknames refer to the ferocity of the fighting, the intensity of Japanese kamikaze attacks, and the sheer numbers of Allied ships and armored vehicles that assaulted the island. The battle was one of the bloodiest in the Pacific, with approximately 160,000+ casualties on both sides: at least 75,682 Allied and 84,166–117,000 Japanese,[26] including drafted Okinawans wearing Japanese uniforms.[16] 149,425 Okinawans were killed, committed suicide or went missing, a significant proportion of the estimated pre-war 300,000 local population.[26] In the naval operations surrounding the battle, both sides lost considerable numbers of ships and aircraft, including the Japanese battleship Yamato. After the battle, Okinawa provided a fleet anchorage, troop staging areas, and airfields in proximity to Japan in preparation for the planned invasion.

TF 56 was the largest force within TF 50 and was built around the 10th Army. The army had two corps under its command: the III Amphibious Corps, consisting of 1st and 6th Marine Divisions, and the XXIV Corps, consisting of the 7th and 96th Infantry Divisions. The 2nd Marine Division was an afloat reserve, and the 10th Army also controlled the 27th Infantry Division, earmarked as a garrison, and the 77th Infantry Divisions.[30] In all, the Army had over 102,000 soldiers (of these, 38,000+ were non-divisional artillery, combat support and HQ troops, with another 9,000 service troops),[28] over 88,000 Marines and 18,000 Navy personnel (mostly Seabees
and medical personnel).[30] At the start of the Battle of Okinawa, the 10th Army had 182,821 personnel under its command.[30] It was planned that General Buckner would report to Turner until the amphibious phase was completed, after which he would report directly to Spruance. Although Allied land forces were entirely composed of American units, the British Pacific Fleet
British Pacific Fleet
(BPF; known to the US Navy as Task Force 57) provided about ¼ of Allied naval air power (450 planes). It comprised a force which included 50 warships, of which 17 were aircraft carriers; while the British armored flight decks meant that fewer planes could be carried in a single aircraft carrier, they were more resistant to kamikaze strikes.[citation needed] Although all the aircraft carriers were provided by Britain, the carrier group was a combined British Commonwealth fleet with British, Canadian, New Zealand and Australian ships and personnel.[citation needed] Their mission was to neutralize Japanese airfields in the Sakishima Islands
Sakishima Islands
and provide air cover against Japanese kamikaze attacks. Most of the air-to-air fighters and the small dive bombers and strike aircraft were US Navy carrier-based airplanes. Japanese[edit]

The Japanese land campaign (mainly defensive) was conducted by the 67,000-strong (77,000 according to some sources) regular 32nd Army and some 9,000 Imperial Japanese Navy
Imperial Japanese Navy
(IJN) troops at Oroku naval base (only a few hundred of whom had been trained and equipped for ground combat), supported by 39,000 drafted local Ryukyuan people
Ryukyuan people
(including 24,000 hastily drafted rear militia called Boeitai and 15,000 non-uniformed laborers). The Japanese had used kamikaze tactics since the Battle of Leyte Gulf, but for the first time, they became a major part of the defense. Between the American landing on April 1 and May 25, seven major kamikaze attacks were attempted, involving more than 1,500 planes. The 32nd Army initially consisted of the 9th, 24th, and 62nd Divisions, and the 44th Independent Mixed Brigade. The 9th Division was moved to Taiwan
before the invasion, resulting in shuffling of Japanese defensive plans. Primary resistance was to be led in the south by Lieutenant General
Lieutenant General
Mitsuru Ushijima, his chief of staff, Lieutenant General
Lieutenant General
Isamu Chō and his chief of operations, Colonel Hiromichi Yahara. Yahara advocated a defensive strategy, whilst Chō advocated an offensive one. In the north, Colonel Takehido Udo was in command. The IJN troops were led by Rear Admiral
Minoru Ōta. They expected the Americans to land 6–10 divisions against the Japanese garrison of two and a half divisions. The staff calculated that superior quality and numbers of weapons gave each US division five or six times the firepower of a Japanese division. To this, would be added the Americans' abundant naval and air firepower. Military use of children[edit] In Okinawa island, middle school boys were organized into front-line-service Tekketsu Kinnōtai, while Himeyuri students

Japanese Imperial Army
mobilized 1,780 middle school boys aged 14–17 years into front-line-service. They were named "Tekketsu Kinnōtai" (ja:鉄血勤皇隊, Iron and Blood Imperial Corps). This mobilization was conducted by the ordinance of the Ministry of Army, not by law. The ordinances mobilized the student as a volunteer soldier for form's sake. In reality, the military authorities ordered schools to force almost all students to "volunteer" as soldiers. Sometimes they counterfeited the necessary documents. About half of Tekketsu Kinnōtai were killed, including in suicide bomb attacks against tanks, and in guerrilla operations. After losing the Battle of Okinawa, the Japanese government enacted new laws in preparation for the decisive battles in the main islands. These laws made it possible for boys aged 15 or older and girls aged 17 or older to be drafted into front-line-service.

Naval battle[edit]

There was a hypnotic fascination to the sight so alien to our Western philosophy. We watched each plunging kamikaze with the detached horror of one witnessing a terrible spectacle rather than as the intended victim. We forgot self for the moment as we groped hopelessly for the thought of that other man up there.

Navy's Task Force 58, deployed to the east of Okinawa with a picket group of from 6 to 8 destroyers, kept 13 carriers (7 CVs and 6 CVLs) on duty from March 23 to April 27 and a smaller number thereafter. Until April 27, a minimum of 14 and up to 18 escort carriers (CVEs) were in the area at all times. Until April 20, British Task Force 57, with 4 large and 6 escort carriers, remained off the Sakishima Islands

to protect the southern flank.[33] The protracted length of the campaign under stressful conditions forced Admiral
Chester W. Nimitz
Chester W. Nimitz
to take the unprecedented step of relieving the principal naval commanders to rest and recuperate. Following the practice of changing the fleet designation with the change of commanders, US naval forces began the campaign as the US 5th Fleet under Admiral
Raymond Spruance, but ended it as the 3rd Fleet under Admiral
William Halsey. Japanese air opposition had been relatively light during the first few days after the landings. However, on April 6, the expected air reaction began with an attack by 400 planes from Kyushu. Periodic heavy air attacks continued through April. During the period March 26 – April 30, twenty American ships were sunk and 157 damaged by enemy action. For their part, by April 30, the Japanese had lost more than 1,100 planes to Allied naval forces alone.[34] Between April 6 and June 22, the Japanese flew 1,465 kamikaze aircraft in large-scale attacks from Kyushu, 185 individual kamikaze sorties from Kyushu, and 250 individual kamikaze sorties from Formosa. While US intelligence estimated there were 89 planes on Formosa, the Japanese actually had about 700, dismantled or well camouflaged and dispersed into scattered villages and towns; the US Fifth Air Force disputed Navy claims of kamikaze coming from Formosa.[35][clarification needed] The ships lost were smaller vessels, particularly the destroyers of the radar pickets, as well as destroyer escorts and landing ships. While no major Allied warships were lost, several fleet carriers were severely damaged. Land-based Shin'yō-class suicide motorboats were also used in the Japanese suicide attacks, although Ushijima had disbanded the majority of the suicide boat battalions prior to the battle due to expected low effectiveness against a superior enemy. The boat crews were re-formed into three additional infantry battalions.[36] Operation Ten-Go[edit] Main article: Operation Ten-Go

Operation Ten-Go
Operation Ten-Go
(Ten-gō sakusen) was the attempted attack by a strike force of 10 Japanese surface vessels, led by the super battleship Yamato and commanded by Admiral
Seiichi Itō. This small task force had been ordered to fight through enemy naval forces, then beach Yamato and fight from shore, using her guns as coastal artillery and her crew as naval infantry. The Ten-Go force was spotted by submarines shortly after it left the Japanese home waters, and was intercepted by US carrier aircraft. Under attack from more than 300 aircraft over a two-hour span, the world's largest battleship sank on April 7, 1945, after a one-sided battle, long before she could reach Okinawa. (US torpedo bombers were instructed to aim for only one side to prevent effective counter flooding by the battleship's crew, and to aim for the bow or the stern, where armor was believed to be the thinnest.) Of Yamato's screening force, the light cruiser Yahagi and 4 of the 8 destroyers were also sunk. The Imperial Japanese Navy

lost some 3,700 sailors, including Admiral
Itō, at the cost of 10 US aircraft and 12 airmen. British Pacific Fleet[edit]

The British Pacific Fleet, taking part as Task Force 57, was assigned the task of neutralizing the Japanese airfields in the Sakishima Islands, which it did successfully from March 26 to April 10. On April 10, its attention was shifted to airfields on northern Formosa. The force withdrew to San Pedro Bay on April 23. On May 1, the British Pacific Fleet
British Pacific Fleet
returned to action, subduing the airfields as before, this time with naval bombardment as well as aircraft. Several kamikaze attacks caused significant damage, but since the British had armored flight decks on their aircraft carriers, they experienced only a brief interruption to their force's operations.[37][38] Land battle[edit]

The battleship USS Idaho shells Okinawa on April 1, 1945.

The land battle took place over about 81 days beginning on April 1, 1945. The first Americans ashore were soldiers of the 77th Infantry Division, who landed in the Kerama Islands, 15 mi (24 km) west of Okinawa on March 26. Subsidiary landings followed, and the Kerama group was secured over the next five days. In these preliminary operations, the 77th Infantry Division suffered 27 dead and 81 wounded, while Japanese dead and captured numbered over 650. The operation provided a protected anchorage for the fleet and eliminated the threat from suicide boats. On March 31, Marines of the Fleet Marine Force Amphibious Reconnaissance Battalion landed without opposition on Keise Shima, four islets just 8 mi (13 km) west of the Okinawan capital of Naha. A group of 155 mm (6.1 in) "Long Tom" artillery pieces went ashore on the islets to cover operations on Okinawa. Northern Okinawa[edit]

The main landing was made by the XXIV Corps
and the III Amphibious Corps
on the Hagushi beaches on the western coast of Okinawa on L-Day, April 1, which was both Easter Sunday and April Fools' Day

in 1945. The 2nd Marine Division conducted a demonstration off the Minatoga beaches on the southeastern coast to deceive the Japanese about American intentions and delay movement of reserves from there. The 10th Army swept across[39] the south-central part of the island with relative ease by World War II

standards, capturing the Kadena and the Yomitan airbases within hours of the landing. In light of the weak opposition, General Buckner decided to proceed immediately with Phase II of his plan—the seizure of northern Okinawa. The 6th Marine Division headed up the Ishikawa Isthmus and by April 7, had sealed off the Motobu Peninsula. Six days later on April 13, the 2nd Battalion, 22nd Marine Regiment, reached Hedo Point (Hedo-misaki) at the northernmost tip of the island. By this point, the bulk of the Japanese forces in the north (codenamed Udo Force) were cornered on the Motobu Peninsula. Here, the terrain was mountainous and wooded, with the Japanese defenses concentrated on Yae-Dake, a twisted mass of rocky ridges and ravines on the center of the peninsula. There was heavy fighting before the Marines finally cleared Yae-Dake
on April 18. Meanwhile, the 77th Infantry Division assaulted Ie Island (Ie Shima)—a small island off the western end of the peninsula—on April 16. In addition to conventional hazards, the 77th Infantry Division encountered kamikaze attacks, and even local women armed with spears. There was heavy fighting before the area was declared secured on April 21, and became another air base for operations against Japan. Southern Okinawa[edit]

While the 6th Marine Division
6th Marine Division
cleared northern Okinawa, the US Army 96th and 7th Infantry Divisions wheeled south across the narrow waist of Okinawa. The 96th Infantry Division began to encounter fierce resistance in west-central Okinawa from Japanese troops holding fortified positions east of Highway No. 1 and about 5 mi (8 km) northwest of Shuri, from what came to be known as Cactus Ridge. The 7th Infantry Division encountered similarly fierce Japanese opposition from a rocky pinnacle located about 1,000 yd (910 m) southwest of Arakachi (later dubbed "The Pinnacle"). By the night of April 8, American troops had cleared these and several other strongly fortified positions. They suffered over 1,500 battle casualties in the process, while killing or capturing about 4,500 Japanese. Yet the battle had only begun, for it was now realized that "these were merely outposts," guarding the Shuri Line. The next American objective was Kakazu Ridge, two hills with a connecting saddle that formed part of Shuri's outer defenses. The Japanese had prepared their positions well and fought tenaciously. The Japanese soldiers hid in fortified caves. American forces often lost personnel before clearing the Japanese out from each cave or other hiding place. The Japanese sent Okinawans at gunpoint out to obtain water and supplies for them, which led to civilian casualties. The American advance was inexorable, but resulted in a high number of casualties on both sides. As the American assault against Kakazu Ridge stalled, Lieutenant General Ushijima — influenced by General Chō — decided to take the offensive. On the evening of April 12, the 32nd Army attacked American positions across the entire front. The Japanese attack was heavy, sustained, and well organized. After fierce close combat, the attackers retreated, only to repeat their offensive the following night. A final assault on April 14 was again repulsed. The effort led the 32nd Army's staff to conclude that the Americans were vulnerable to night infiltration tactics, but that their superior firepower made any offensive Japanese troop concentrations extremely dangerous, and they reverted to their defensive strategy. The 27th Infantry Division—which had landed on April 9—took over on the right, along the west coast of Okinawa. General John R. Hodge now had three divisions in the line, with the 96th in the middle, and the 7th to the east, with each division holding a front of only about 1.5 mi (2.4 km). Hodge launched a new offensive of April 19 with a barrage of 324 guns, the largest ever in the Pacific Ocean Theater. Battleships, cruisers, and destroyers joined the bombardment, which was followed by 650 Navy and Marine planes attacking the enemy positions with napalm, rockets, bombs, and machine guns. The Japanese defenses were sited on reverse slopes, where the defenders waited out the artillery barrage and aerial attack in relative safety, emerging from the caves to rain mortar rounds and grenades upon the Americans advancing up the forward slope. A tank assault to achieve breakthrough by outflanking Kakazu Ridge failed to link up with its infantry support attempting to cross the ridge, and therefore failed with the loss of 22 tanks. Although flame tanks cleared many cave defenses, there was no breakthrough, and the XXIV Corps
suffered 720 casualties. The losses might have been greater except for the fact that the Japanese had practically all of their infantry reserves tied up farther south, held there by another feint off the Minatoga beaches by the 2nd Marine Division that coincided with the attack. At the end of April, after Army forces had pushed through the Machinato defensive line,[40] the 1st Marine Division relieved the 27th Infantry Division, and the 77th Infantry Division relieved the 96th. When the 6th Marine Division

arrived, the III Amphibious Corps took over the right flank and the 10th Army assumed control of the battle.

On May 4, the 32nd Army launched another counteroffensive. This time, Ushijima attempted to make amphibious assaults on the coasts behind American lines. To support his offensive, the Japanese artillery moved into the open. By doing so, they were able to fire 13,000 rounds in support, but effective American counter-battery fire destroyed dozens of Japanese artillery pieces. The attack failed. Buckner launched another American attack on May 11. Ten days of fierce fighting followed. On May 13, troops of the 96th Infantry Division and 763rd Tank Battalion captured Conical Hill. Rising 476 ft (145 m) above the Yonabaru coastal plain, this feature was the eastern anchor of the main Japanese defenses and was defended by about 1,000 Japanese. Meanwhile, on the opposite coast, the 1st and 6th Marine Divisions fought for "Sugar Loaf Hill". The capture of these two key positions exposed the Japanese around Shuri on both sides. Buckner hoped to envelop Shuri and trap the main Japanese defending force. By the end of May, monsoon rains which had turned contested hills and roads into a morass exacerbated both the tactical and medical situations. The ground advance began to resemble a World War I battlefield, as troops became mired in mud, and flooded roads greatly inhibited evacuation of wounded to the rear. Troops lived on a field sodden by rain, part garbage dump and part graveyard. Unburied Japanese and American bodies decayed, sank in the mud, and became part of a noxious stew. Anyone sliding down the greasy slopes could easily find their pockets full of maggots at the end of the journey.[41] On May 29, Major General
Major General
Pedro del Valle, commander of the 1st Marine Division, ordered Captain Julian D. Dusenbury of[42] Company A, 1st Battalion, 5th Marines, to capture Shuri Castle. Seizure of the castle represented both strategic and psychological blows for the Japanese and was a milestone in the campaign. Del Valle was awarded a Distinguished Service Medal for his leadership in the fight and the subsequent occupation and reorganization of Okinawa. Captain Dusenbury would later receive the Navy Cross for his actions.[42] Shuri Castle
Shuri Castle
had been shelled by the battleship USS Mississippi for three days before this advance.[43] Due to this, the 32nd Army withdrew to the south and thus the Marines had an easy task of securing Shuri Castle.[43][44] The castle, however, was outside the 1st Marine Division's assigned zone and only frantic efforts by the commander and staff of the 77th Infantry Division prevented an American air strike and artillery bombardment which would have resulted in many casualties due to friendly fire. The Japanese retreat, although harassed by artillery fire, was conducted with great skill at night and aided by the monsoon storms. The 32nd Army was able to move nearly 30,000 personnel into its last defense line on the Kiyan Peninsula, which ultimately led to the greatest slaughter on Okinawa in the latter stages of the battle, including the deaths of thousands of civilians. In addition, there were 9,000 IJN troops supported by 1,100 militia, with approximately 4,000 holed up at the underground headquarters on the hillside overlooking the Okinawa Naval Base in the Oroku Peninsula, east of the airfield. On June 4, elements of the 6th Marine Division
6th Marine Division
launched an amphibious assault on the peninsula. The 4,000 Japanese sailors, including Admiral
Minoru Ōta, all committed suicide within the hand-built tunnels of the underground naval headquarters on June 13. By June 17, the remnants of Ushijima's shattered 32nd Army were pushed into a small pocket in the far south of the island to the southeast of Itoman. On June 18, General Buckner was killed by enemy artillery fire while monitoring the forward progress of his troops. Buckner was replaced by Roy Geiger. Upon assuming command, Geiger became the only US Marine to command a numbered army of the US Army in combat; he was relieved five days later by Joseph Stilwell. The last remnants of Japanese resistance ended on June 21, although some Japanese continued hiding, including the future governor of Okinawa Prefecture, Masahide Ōta.[45] Ushijima and Chō committed suicide by seppuku in their command headquarters on Hill 89 in the closing hours of the battle. Colonel Yahara had asked Ushijima for permission to commit suicide, but the general refused his request, saying: "If you die there will be no one left who knows the truth about the battle of Okinawa. Bear the temporary shame but endure it. This is an order from your army Commander."[46] Yahara was the most senior officer to have survived the battle on the island, and he later authored a book titled The Battle for Okinawa.

Military losses[edit] American[edit]

The Americans suffered over 82,000 casualties, including non-battle casualties (psychiatric, injuries, illnesses), of whom over 12,500 were killed or missing. Battle deaths were 4,907 Navy, 4,675 Army, and 2,938 Marine Corps
personnel.[9] Several thousand personnel who died indirectly (from wounds and other causes) at a later date are not included in the total. The most famous American casualty was Lieutenant General
Lieutenant General
Simon Bolivar Buckner Jr., whose decision to attack the Japanese defenses head-on, although extremely costly in American lives, was ultimately successful. Four days from the closing of the campaign, Buckner was killed by Japanese artillery fire, which blew lethal slivers of coral into his body, while inspecting his troops at the front line. He was the highest-ranking US officer to be killed by enemy fire during the Second World War. The day after Buckner was killed, Brigadier General Claudius Miller Easley
Claudius Miller Easley
was killed by sniper fire. The famous war correspondent Ernie Pyle, was killed by Japanese sniper fire on Ie Island (Ie Shima, a small island just off of northwestern Okinawa).[54] Aircraft losses over the three-month period were 768 US planes, including those bombing the Kyushu
airfields launching kamikazes. Combat losses were 458, and the other 310 were operational accidents. On land, at least 225 tanks and many LVTs were lost. At sea, 368 Allied ships—including 120 amphibious craft—were damaged while another 36—including 15 amphibious ships and 12 destroyers—were sunk during the Okinawa campaign. The US Navy's dead exceeded its wounded, with 4,907 killed and 4,874 wounded, primarily from kamikaze attacks.[55] American personnel casualties included thousands of cases of mental breakdown. According to the account of the battle presented in Marine Corps

More mental health issues arose from the Battle of Okinawa
Battle of Okinawa
than any other battle in the Pacific during World War II. The constant bombardment from artillery and mortars coupled with the high casualty rates led to a great deal of personnel coming down with combat fatigue. Additionally the rains caused mud that prevented tanks from moving and tracks from pulling out the dead, forcing Marines (who pride themselves on burying their dead in a proper and honorable manner) to leave their comrades where they lay. This, coupled with thousands of bodies both friend and foe littering the entire island, created a scent you could nearly taste. Morale was dangerously low by the month of May and the state of discipline on a moral basis had a new low barometer for acceptable behavior. The ruthless atrocities by the Japanese throughout the war had already brought on an altered behavior (deemed so by traditional standards) by many Americans resulting in the desecration of Japanese remains, but the Japanese tactic of using the Okinawan people as human shields brought about a new aspect of terror and torment to the psychological capacity of the Americans.[16]

Japanese losses[edit] The US military estimates that 110,071 Japanese soldiers were killed during the battle. This total includes conscripted Okinawan civilians.

A total of 7,401 Japanese regulars and 3,400 Okinawan conscripts surrendered or were captured during the battle. Additional Japanese and renegade Okinawans were captured or surrendered over the next few months, bringing the total to 16,346.[56] This was the first battle in the Pacific War
Pacific War
in which thousands of Japanese soldiers surrendered or were captured. Many of the prisoners were native Okinawans who had been pressed into service shortly before the battle, and were less imbued with the Imperial Japanese Army's no-surrender doctrine.[57] When the American forces occupied the island, many Japanese soldiers put on Okinawan clothing to avoid capture, and some Okinawans would come to the Americans' aid by offering to identify these mainland Japanese. The Japanese lost 16 combat vessels, including the super battleship Yamato. Postwar examination of Japanese records revealed that Japanese aircraft losses at Okinawa were far below often-repeated US estimates for the campaign.[17] The number of conventional and kamikaze aircraft actually lost or expended by the 3rd, 5th, and 10th Air Fleets, combined with about 500 lost or expended by the Imperial Army at Okinawa, was roughly 1,430.[17] The Allies destroyed 27 Japanese tanks and 743 artillery pieces (including mortars, anti-tank and anti-aircraft guns), some of them eliminated by the naval and air bombardments but most knocked out by American counter-battery fire. Civilian losses, suicides, and atrocities[edit]

§ Last telegram Some of the other islands that saw major battles in World War II, such as Iwo Jima, were uninhabited or had been evacuated. Okinawa, by contrast, had a large indigenous civilian population; US Army records from the planning phase of the operation make the assumption that Okinawa was home to about 300,000 civilians. According to various estimates, between a tenth and a third of them died during the battle,[41] between 30,000 and 100,000. Okinawa Prefecture's estimate is over 100,000 losses,[58] while the official US Army count for the 82-day campaign is a total of 142,058 civilian casualties, including those killed by artillery fire, air attacks, and those pressed into service by the Imperial Japanese Army.[41] During the battle, American soldiers found it difficult to distinguish civilians from soldiers. It became common for them to shoot at Okinawan houses, as one infantryman wrote:

There was some return fire from a few of the houses, but the others were probably occupied by civilians – and we didn't care. It was a terrible thing not to distinguish between the enemy and women and children. Americans always had great compassion, especially for children. Now we fired indiscriminately.[59]

In its history of the war, the Okinawa Prefectural Peace Memorial Museum[58] presents Okinawa as being caught between the United States and Japan. During the 1945 battle, the Imperial Japanese Army
Imperial Japanese Army
showed indifference to Okinawans' safety, and its soldiers even used civilians as human shields or just outright murdered them. The Japanese military confiscated food from the Okinawans and executed those who hid it, leading to mass starvation, and forced civilians out of their shelters. Japanese soldiers also killed about 1,000 people who spoke in the Okinawan language
Okinawan language
to suppress spying.[60] The museum writes that "some were blown apart by [artillery] shells, some finding themselves in a hopeless situation were driven to suicide, some died of starvation, some succumbed to malaria, while others fell victim to the retreating Japanese troops."[58]

Overcoming the civilian resistance on Okinawa was aided by US propaganda leaflets, one of which is being read by a prisoner awaiting transport.

With the impending Japanese defeat, civilians often committed mass suicide, urged on by the Japanese soldiers who told locals that victorious American soldiers would go on a rampage of killing and raping. Ryūkyū Shimpō, one of the two major Okinawan newspapers, wrote in 2007: "There are many Okinawans who have testified that the Japanese Army directed them to commit suicide. There are also people who have testified that they were handed grenades by Japanese soldiers" to blow themselves up.[61] Thousands of civilians, having been induced by Japanese propaganda to believe that American soldiers were barbarians who committed horrible atrocities, killed their families and themselves to avoid capture. Some of them threw themselves and their family members from the southern cliffs where the Peace Museum now resides.[62] Okinawans "were often surprised at the comparatively humane treatment they received from the American enemy".[63][64] Islands of Discontent: Okinawan Responses to Japanese and American Power by Mark Selden notes that the Americans "did not pursue a policy of torture, rape, and murder of civilians as Japanese military officials had warned".[65] American Military Intelligence Corps[66] combat translators such as Teruto Tsubota
Teruto Tsubota
managed to convince many civilians not to kill themselves.[67] Survivors of the mass suicides blamed also the indoctrination of their education system of the time, in which the Okinawans were taught to become "more Japanese than the Japanese", and were expected to prove it.[68] Witnesses and historians reported that soldiers, mainly Japanese troops, raped Okinawan women during the battle. Rape by Japanese troops "became common"[attribution needed] in June, after it became clear that the Imperial Japanese Army
Imperial Japanese Army
had been defeated.[31][69] Marine Corps
officials in Okinawa and Washington have said that they knew of no rapes by American personnel in Okinawa at the end of the war.[70] There are, however, numerous credible testimony accounts which allege that a large number of rapes were committed by American forces during the battle. This includes claimed rape after trading sexual favors or even marrying Americans,[71] such as the alleged incident in the village of Katsuyama, where civilians said they had formed a vigilante group to ambush and kill three black American soldiers whom they claimed would frequently rape the local girls there.[72] MEXT controversy[edit] There is ongoing disagreement between Okinawa's local government and Japan's national government over the role of the Japanese military in civilian mass suicides during the battle. In March 2007, the national Ministry of Education, Culture, Sports, Science and Technology
Ministry of Education, Culture, Sports, Science and Technology
(MEXT) advised textbook publishers to reword descriptions that the embattled Imperial Japanese Army
Imperial Japanese Army
forced civilians to kill themselves in the war to avoid being taken prisoner. MEXT preferred descriptions that just say that civilians received hand grenades from the Japanese military. This move sparked widespread protests among Okinawans. In June 2007, the Okinawa Prefectural Assembly
Okinawa Prefectural Assembly
adopted a resolution stating, "We strongly call on the (national) government to retract the instruction and to immediately restore the description in the textbooks so the truth of the Battle of Okinawa
Battle of Okinawa
will be handed down correctly and a tragic war will never happen again."[73][74] On September 29, 2007, about 110,000 people held the biggest political rally in the history of Okinawa to demand that MEXT retract its order to textbook publishers regarding revising the account of the civilian suicides. The resolution stated, "It is an undeniable fact that the 'multiple suicides' would not have occurred without the involvement of the Japanese military and any deletion of or revision to (the descriptions) is a denial and distortion of the many testimonies by those people who survived the incidents."[75] In December 2007, MEXT partially admitted the role of the Japanese military in civilian mass suicides.[76] The ministry's Textbook Authorization Council allowed the publishers to reinstate the reference that civilians "were forced into mass suicides by the Japanese military", on condition it is placed in sufficient context. The council report stated, "It can be said that from the viewpoint of the Okinawa residents, they were forced into the mass suicides."[77] That was not enough for the survivors who said it is important for children today to know what really happened.[78] The Nobel Prize-winning author Kenzaburō Ōe
Kenzaburō Ōe
wrote a booklet which states that the mass suicide order was given by the military during the battle.[79] He was sued by revisionists, including a wartime commander during the battle, who disputed this and wanted to stop publication of the booklet. At a court hearing, Ōe testified "Mass suicides were forced on Okinawa islanders under Japan's hierarchical social structure that ran through the state of Japan, the Japanese armed forces and local garrisons."[80] In March 2008, the Osaka Prefecture Court ruled in favor of Ōe, stating, "It can be said the military was deeply involved in the mass suicides." The court recognized the military's involvement in the mass suicides and murder-suicides, citing the testimony about the distribution of grenades for suicide by soldiers and the fact that mass suicides were not recorded on islands where the military was not stationed.[81] In 2012, Korean-Japanese director Pak Su-nam announced her work on the documentary Nuchigafu (Okinawan for "only if one is alive") collecting living survivors' accounts to show "the truth of history to many people", alleging that "there were two types of orders for 'honorable deaths'—one for residents to kill each other and the other for the military to kill all residents".[82] In March 2013, Japanese textbook publisher Shimizu Shoin was permitted by MEXT to publish the statements that "Orders from Japanese soldiers led to Okinawans committing group suicide" and "The [Japanese] army caused many tragedies in Okinawa, killing local civilians and forcing them to commit mass suicide."[83] Aftermath[edit]

Ninety percent of the buildings on the island were destroyed, along with countless historical documents, artifacts, and cultural treasures, and the tropical landscape was turned into "a vast field of mud, lead, decay and maggots".[84] The military value of Okinawa "exceeded all hope". Okinawa provided a fleet anchorage, troop staging areas, and airfields in proximity to Japan. The US cleared the surrounding waters of mines in Operation Zebra, occupied Okinawa, and set up the United States
United States
Civil Administration of the Ryukyu Islands, a form of military government, after the battle.[85] In 2011, one official of the prefectural government told David Hearst of The Guardian:

You have the Battle of Britain, in which your airmen protected the British people. We had the Battle of Okinawa, in which the exact opposite happened. The Japanese army not only starved the Okinawans but used them as human shields. That dark history is still present today – and Japan and the US should study it before they decide what to do with next.[86]

Effect on the wider war[edit] Because the next major event following the Battle of Okinawa
Battle of Okinawa
was "the total surrender of Japan," the "effect" of this battle is more difficult to consider. Due to the surrender, the next anticipated series of battles – an invasion of the Japanese homeland – never occurred. (Therefore, all military strategies on both sides which presupposed this apparently-inevitable next development were immediately rendered moot.) Some military historians believe that the Okinawa campaign led directly to the atomic bombings of Hiroshima and Nagasaki, as a means of avoiding the planned ground invasion of the Japanese mainland. This view is explained by Victor Davis Hanson
Victor Davis Hanson
in his book Ripples of Battle:

... because the Japanese on Okinawa ... were so fierce in their defense (even when cut off, and without supplies), and because casualties were so appalling, many American strategists looked for an alternative means to subdue mainland Japan, other than a direct invasion. This means presented itself, with the advent of atomic bombs, which worked admirably in convincing the Japanese to sue for peace [unconditionally], without American casualties.

Meanwhile, many parties continue to debate the broader question of "why Japan surrendered", attributing the surrender to a number of possible reasons including: the atomic bombings,[87][88][89] the Soviet invasion of Manchuria,[90][91] and Japan's depleted resources.[92][page needed][93] Memorial[edit] In 1995, the Okinawa government erected a memorial monument named the Cornerstone of Peace
Cornerstone of Peace
in Mabuni, the site of the last fighting in southeastern Okinawa.[94] The memorial lists all the known names of those who died in the battle, civilian and military, Japanese and foreign. As of June 2008, it contains 240,734 names.[95] Modern US base[edit] Significant US forces remain garrisoned on Okinawa as the United States Forces Japan, which the Japanese government sees as an important guarantee of regional stability,[96] and Kadena remains the largest US air base in Asia. Local residents have protested against the size and presence of the base.[97][98] See also[edit]
