Air raids on Japan

September 1945 the Japanese government offered to provide material for 300,000 small temporary houses to evacuees, but the emphasis of its policies in this year and 1946 was to stop people returning to the damaged cities. The reconstruction of 115 cities began in 1946, and this work was conducted in line with guidelines developed by the Japanese government. The Allied occupation authorities were not involved in the urban rebuilding effort, but allowed this work to go ahead despite criticizing it as inappropriate to Japan's status as a defeated country. Requisitions of land and buildings for use by the occupation force and a requirement that the Japanese government prioritize the construction of housing for the Allied troops interfered with reconstruction, however. In many cities rebuilding was accompanied by a process of land readjustment which sought to improve the urban layout, though the success of both such readjustment and rebuilding programs varied between locations. Overall, most of the new buildings constructed were of poor quality, and it was not until well after the war that major

Japanese forces; the majority of the losses were due to flying accidents. The attacks had a limited impact on Japanese civilian morale but forced the Japanese military to reinforce the home islands' air defenses at the expense of other areas. These results did not justify the large allocation of Allied resources to the operation, however. Moreover, the diversion of some supply aircraft flown between India and China to support XX Bomber Command's efforts may have prevented the Fourteenth Air Force from undertaking more effective operations against Japanese positions and shipping. The official history of the USAAF judged that the difficulty of transporting adequate supplies to India and China was the most important factor behind the failure of Operation Matterhorn, though technical problems with the B-29s and the inexperience of their crews also hindered the campaign. The adverse weather conditions common over Japan also limited the effectiveness of the Superfortresses, as crews that managed to reach their target were often unable to bomb accurately due to high winds or cloud cover.

3018: 3205:. As a result, few of the subsequent Allied raids were intercepted. The effectiveness of Japanese anti-aircraft batteries also decreased during 1945 as the collapse of the national economy led to severe shortages of ammunition. Moreover, as the anti-aircraft guns were mainly stationed near major industrial areas, many of the raids on small cities were almost unopposed. Imperial General Headquarters decided to resume attacks on Allied bombers from late June, but by this time there were too few fighters available for this change of tactics to have any effect. The number of fighters assigned to the Air General Army peaked at just over 500 during June and July, but most frontline units had relatively few serviceable aircraft. During the last weeks of the war Superfortresses were able to operate with near impunity owing to the weakness of the Japanese air defenses; LeMay later claimed that during this period "it was safer to fly a combat mission over Japan than it was to fly a B-29 training mission back in the United States". 3053:, sinking three small warships and 12 merchant vessels, before the fleet sailed east to avoid a typhoon and replenish its supplies. Its next attacks against Japan took place on 9 and 10 August, and were directed at a buildup of Japanese aircraft in northern Honshu which Allied intelligence believed were to be used to conduct a commando raid against the B-29 bases in the Marianas. The naval aviators claimed to have destroyed 251 aircraft in their attacks on 9 August and damaged a further 141. On 13 August, TF 38's aircraft attacked the Tokyo region again and claimed to have destroyed 254 Japanese aircraft on the ground and 18 in the air. Another raid was launched against Tokyo on the morning of 15 August, and the 103 aircraft of its first wave attacked their targets. The second wave aborted its attack when word was received that Japan had agreed to surrender. Several Japanese aircraft were shot down while attempting to attack TF 38 later that day, however. 3689:

bombing caused to Japan's economy, however, as the Allied naval blockade also contributed to general breakdown which occurred from late 1944. Statistics compiled by the USSBS show a correlation between the number of B-29 sorties directed at different industries and the amount by which their production declined, but air attacks were not the only reason for these differences. In addition to the heavy bomber attacks, the operations by Allied aircraft carriers tightened the blockade by disrupting Japanese coastal shipping; the naval aircraft were unable to carry enough bombs to seriously damage Japanese industrial plants, however. Compounding the effects of the air attacks, Japan's rice crop of 1945 failed. The resulting shortage of rice caused widespread malnutrition, and mass starvation would have occurred had the war continued. In financial terms, the Allied air campaign and attacks on merchant ships destroyed between one third and a quarter of Japan's wealth.

factory in Tokyo on 10 August. The next day, President Truman ordered a halt to the bombing due to the possibility that it would be interpreted as a sign that the peace negotiations had failed. On 11 August, Spaatz issued a new targeting directive for any renewed attacks that reduced the emphasis on bombing cities in favor of intensified attacks on transport infrastructure. On 13 August, B-29s dropped copies of the Japanese government's conditional offer to surrender over Japanese cities. Negotiations appeared to be stalled, and on 14 August Spaatz received orders to resume the bombing campaign. Arnold requested the largest attack possible, and hoped that USASTAF could dispatch 1,000 aircraft against the Tokyo region and other locations in Japan. In fact, 828 B-29s escorted by 186 fighters (for a total of 1,014 aircraft) were dispatched; during the day precision raids were made against targets at Iwakuni, Osaka and Tokoyama and at night the cities of

2869: 3460: 2462:; 300,000 houses were destroyed in Osaka. This attack marked the end of the first phase of XXI Bomber Command's attack on Japan's cities. During May and June the bombers had destroyed much of the country's six largest cities, killing between 112,000 and 126,762 people and rendering millions homeless. The widespread destruction and high number of casualties from these raids caused many Japanese to realize that their country's military was no longer able to defend the home islands. American losses were low compared to Japanese casualties; 136 B-29s were downed during the campaign. In Tokyo, Osaka, Nagoya, Yokohama, Kobe, and Kawasaki, "over 126,762 people were killed ... and a million and a half dwellings and over 105 square miles (270 km) of urban space were destroyed." In Tokyo, Osaka and Nagoya, "the areas leveled (almost 100 square miles (260 km)) exceeded the areas 2299: 3788:. While conventional attacks inflicted more damage and casualties on Japan than the atomic bombs, discussions of the air campaign have been focused on the use of nuclear weapons. Shortly after the atomic bombings an opinion poll found that about 85 percent of Americans supported the use of atomic weapons, and the wartime generation believed that they had saved millions of lives. Criticisms over the decision to use the bombs have increased over time, however. Arguments made against the attacks include that Japan would have eventually surrendered and that the attacks were made to either intimidate the Soviet Union or justify the Manhattan Project. In 1994, an opinion poll found that 55 percent of Americans supported the decision to bomb Hiroshima and Nagasaki. When registering the only dissenting opinion of the judges involved in the 3720: 1854: 2812: 2082:, was made against the Musashino aircraft plant in the outskirts of Tokyo on 24 November 1944. Only 24 of the 111 B-29s dispatched attacked the primary target, and the others bombed port facilities as well as industrial and urban areas. The Americans were intercepted by 125 Japanese fighters but only one B-29 was shot down. This attack caused some damage to the aircraft plant and further reduced Japanese civilians' confidence in the country's air defenses. In response, the IJAAF and IJN stepped up their air attacks on B-29 bases in the Mariana Islands from 27 November; these raids continued until January 1945 and resulted in the destruction of 11 Superfortresses and damage to another 43 for the loss of probably 37 Japanese aircraft. The IJA also began launching 2860:

the B-29s, however. Many of Japan's major harbors, including those of Tokyo, Yokohama and Nagoya, became closed to shipping. During the last weeks of the war, B-29s continued to drop large numbers of mines off Japan and the campaign was expanded into Korean waters. The 313th Bombardment Wing lost only 16 B-29s during mine-laying operations. Overall, mines dropped by Superfortresses off the home islands sank 293 ships, which represented 9.3 percent of all Japanese merchant shipping destroyed during the Pacific War and 60 percent of losses between April and August 1945. Following the war, the USSBS assessed that the Twentieth Air Force should have placed a greater emphasis on attacking Japanese shipping given the effectiveness of these attacks.

LeMay's plan called for precision attacks on important industrial targets on days when the weather over Japan was clear and incendiary attacks guided by radar on overcast days. As both the cities and industrial facilities targeted were relatively small, the B-29 force would be sent against multiple locations on days in which attacks were conducted. This targeting policy, which was labeled the "Empire Plan", remained in force until the last days of the war. 2049: 3062: 2518:, Mizushima and Akashi in southern Honshu. Most of the factories targeted were badly damaged. Four days later, 510 B-29s escorted by 148 P-51s were sent against nine factories in southern Honshu and Shikoku. Heavy clouds over the region meant that many bombers attacked targets of opportunity individually or in small groups, and little damage was done to the raid's intended targets. Cloudy weather prevented any further large-scale precision attacks until 24 July, when 625 B-29s were dispatched against seven targets near Nagoya and Osaka. Four of the factories attacked suffered heavy damage. Renewed cloudy weather prevented any further Empire Plan precision attacks in the last weeks of the war. 2127:

area attacks. In late December 1944 Arnold decided to relieve Hansell of his command. Seeing LeMay's success in improving XX Bomber Command's performance, Arnold thought LeMay could solve the problems at XXI Bomber Command, and replaced Hansell with him. Hansell was informed of Arnold's decision on 6 January, but remained in his position until mid-January. During this period, XXI Bomber Command conducted unsuccessful precision bombing attacks on the Musashino aircraft plant in Tokyo and a Mitsubishi Aircraft Works factory in Nagoya on 9 and 14 January respectively. The last attack planned by Hansell was more successful, however: a force of 77 B-29s crippled a

Superfortress was shot down during this attack, and all members of its crew were rescued after the aircraft ditched into the sea. This raid marked the end of the first firebombing campaign as XXI Bomber Command had exhausted its supplies of incendiary bombs. The Command's next major operation was an unsuccessful night precision attack on the Mitsubishi aircraft engine factory conducted on the night of 23/24 March; during this operation five of the 251 aircraft dispatched were shot down. B-29s also began to drop propaganda leaflets over Japan during March. These leaflets called on Japanese civilians to overthrow their government or face destruction.

Nevertheless, 458 heavy bombers and 27 P-51s reached the city and the bombardment killed 3,960 Japanese and destroyed 3.15 square miles (8.2 km) of buildings. On 5 June 473 B-29s struck Kobe by day and destroyed 4.35 square miles (11.3 km) of buildings for the loss of 11 bombers. A force of 409 B-29s attacked Osaka again on 7 June; during this attack 2.21 square miles (5.7 km) of buildings were burnt out and the Americans did not suffer any losses. Osaka was bombed for the fourth time in the month on 15 June when 444 B-29s destroyed 1.9 square miles (4.9 km) of the city and another 0.59 square miles (1.5 km) of nearby

a strong defense that downed two Superfortresses and damaged another 64; another eight B-29s were lost to other causes. The Americans claimed 18 Japanese fighter "kills" as well as another 30 "probables" and 16 damaged. Nagoya was attacked again by 457 B-29s on the night of 16 May, and the resulting fires destroyed 3.82 square miles (9.9 km) of the city. Japanese defenses were much weaker by night, and the three bombers lost in this attack crashed due to mechanical problems. The two raids on Nagoya killed 3,866 Japanese and rendered another 472,701 homeless. On 19 May 318 B-29s conducted an unsuccessful precision bombing raid on the

2487: 1874:. A small number of sophisticated shelters were constructed for air defense headquarters and to protect key telephone facilities. However, less than two percent of civilians had access to bombproof air-raid shelters, though tunnels and natural caves were also used to protect civilians from B-29 raids. Following the outbreak of war, the Home Ministry expanded the number of firefighters, though these generally remained volunteers who lacked adequate training and equipment. Civilians were also trained to fight fires and encouraged to swear an "air defense oath" to respond to attacks from incendiary or high explosive bombs. 3542: 2970: 2252: 2103: 225: 214: 203: 192: 181: 170: 3387: 2222:

Arnold's targeting directive for XXI Bomber Command, which specified that urban areas were to be accorded the second-highest priority for attacks after aircraft factories. The directive also stated that firebombing raids should be conducted once M-69 bombs had been tested in combat and the number of B-29s available was sufficient to launch an intensive campaign. LeMay did not seek Arnold's specific approval before launching his firebombing campaign, however, to protect the USAAF commander from criticism if the attacks were unsuccessful.

justifications for authorizing the surrender. To achieve this, the American Twentieth Strategic Air Force, in concert with its Allies, dropped 160,800 tons of bombs on the Japanese home islands. Of this total, 147,000 tons of bombs were dropped by the B-29 bomber force. Around 90 percent of the American tonnage fell in the last five months of the war. The financial cost of the campaign to the United States was $ 4 billion; this expenditure was much lower than the $ 30 billion spent on bomber operations in Europe, and a small proportion of the $ 330 billion the US Government spent on the war.

a million lost their homes; postwar estimates of deaths in this attack have ranged from 80,000 to 100,000. Damage to Tokyo's war production was also substantial. Japanese opposition to this attack was relatively weak; 14 B-29s were destroyed as a result of combat or mechanical faults and a further 42 damaged by anti-aircraft fire. Following the attack on Tokyo, the Japanese government ordered the evacuation of all schoolchildren in the third to sixth grades from the main cities, and 87 percent of them had departed to the countryside by early April.

3289: 2898:. The actual Japanese aircraft losses in this operation are uncertain, however; the Imperial General Headquarters admitted losing 78 aircraft in dogfights and did not provide a figure for those destroyed on the ground. TF 58's ships were not attacked during this period in Japanese waters, and on 18 February sailed south to provide direct support to the landings on Iwo Jima. The Task Force attempted a second raid against the Tokyo area on 25 February, but this operation was frustrated by bad weather. The American ships sailed south, and attacked 247: 45: 2840: 2332: 2950:

their losses as 161 of the 191 aircraft they committed in the air and an unspecified number on the ground. From 23 March, TF 58 conducted strikes against Okinawa, though its aircraft made further sweeps of Kyushu on 28 and 29 March. Following the landing on 1 April, TF 58 provided air defense for the naval force off Okinawa and regularly conducted patrols over Kyushu. In an attempt to stem the large-scale Japanese air attacks against the Allied ships, part of TF 58 struck at kamikaze aircraft bases on Kyushu and

2783:. On the night of 6/7 July the 315th Bombardment Wing destroyed the Maruzen oil refinery near Osaka, and three nights later it completed the destruction of the Utsube refinery. The wing had conducted 15 operations against Japanese oil facilities by the end of the war. During these attacks it destroyed six of the nine targets attacked for the loss of four B-29s. However, as Japan had almost no crude oil to refine due to the Allied naval blockade of the home islands these raids had little impact on the country's war effort. 3170: 2698: 134: 2450: 2551: 12234: 3375:" atomic bomb over the center of the city. The resulting explosion killed tens of thousands of people and destroyed about 4.7 square miles (12 km) of buildings. The six American aircraft involved in this attack returned safely to the Marianas. Postwar estimates of casualties from the attack on Hiroshima range from 35,000 to 50,000 fatalities and 69,000 to 151,000 injured. More subsequently died as a result of radiation and other injuries. Of the survivors of the bombing, 171,000 were rendered homeless. 3550: 2982:

aircraft, but the two forces often operated separately. On 10 July TF 38's aircraft conducted raids on airfields in the Tokyo region, destroying several aircraft on the ground. No Japanese fighters were encountered in the air, however, as they were being kept in reserve for a planned large-scale suicide attack on the Allied fleet. Following this raid TF 38 steamed north, and began a major attack on Hokkaido and northern Honshu on 14 July. These strikes continued the next day, and sank 8 of the 12

gun range, the well-built B-29s were often able to sustain large amounts of damage. Due to the difficulty of intercepting and downing B-29s, the Japanese fighter pilots increasingly perceived their efforts as being futile. From August 1944 Japanese aircraft occasionally conducted suicide ramming attacks on B-29s, and several specialized kamikaze fighter units were established in October; by the end of the war, ramming tactics had destroyed nine B-29s and damaged another 13 for the loss of 21 fighters.

were destroyed. The cities were almost undefended and no B-29s were lost to Japanese actions. This operation was judged a success, and set the pattern for XXI Bomber Command's firebombing attacks until the end of the war. As the campaign continued and the most important cities were destroyed, the bombers were sent against smaller and less significant cities. On most nights that raids were conducted, four cities were attacked, each by a wing of bombers. Two-wing operations were conducted against

both fighters and bombers, and the city of Kagoshima was frequently bombed. Seventh Air Force B-24 Liberators also bombed the railway terminals in the port of Nagasaki on 31 July and 1 August. While these raids were focused on tactical targets, the Okinawa-based aircraft made several strategic attacks against industrial facilities; these included an unsuccessful raid on a coal liquefaction plant at Ōmuta on 7 August. Bombers of the Fifth and Seventh Air Forces also made firebombing attacks against

developing strategies for the air campaign against Japan, developed plans for a two-stage campaign against 22 Japanese cities. The JTG also recommended that precision bombing attacks on particularly important industrial facilities continue in parallel to the area raids, however. While this campaign was intended to form part of preparations for the Allied invasion of Japan, LeMay and some members of Arnold's staff believed that it alone would be sufficient to force the country's surrender.

3761:, who served as an officer in the Army Air Forces under General Curtis LeMay during the bombings of Japan, LeMay once said that had the United States lost the war they would have been tried for war crimes, McNamara agrees with this assessment. McNamara believed that, "He (LeMay), and I'd say I, were behaving as war criminals." and that "LeMay recognized that what he was doing would be thought immoral if his side had lost. But what makes it immoral if you lose and not immoral if you win?" 3476:

until 20 September. During this period the B-29s flew almost 1,000 sorties and delivered close to 4,500 tons of supplies. Eight aircraft crashed during these missions and another was damaged by a Soviet fighter over Korea. The 3d Photographic Reconnaissance Squadron, which had operated over Japan throughout the bombing campaign, also continued its photo reconnaissance and mapping flights over the home islands during this period. While Spaatz ordered that B-29s and fighters fly continuous

in urban areas. The planners estimated that incendiary bomb attacks on Japan's six largest cities could cause physical damage to almost 40 percent of industrial facilities and result in the loss of 7.6 million man-months of labor. It was also estimated that these attacks would kill over 500,000 people, render about 7.75 million homeless and force almost 3.5 million to be evacuated. The USAAF tested the effectiveness of incendiary bombs on Japanese-style buildings at

industrial areas frequently intercepted American air raids between 24 November 1944 and 25 February 1945, and inflicted significant losses for a period. The number of fighters available declined from late January, however. Poor coordination between the IJAAF and IJN also continued to hamper Japan's defensive efforts throughout this period. The Americans suffered few losses from Japanese fighters during the night raids which were conducted from March 1945 until the end of the war.

1841:). By late June the air defense units in the home islands were assigned 260 fighters, and could draw on approximately 500 additional aircraft during emergencies. Additional anti-aircraft gun batteries and searchlight units were also established to protect major cities and military bases. The GDC's authority was strengthened when the army units in the Eastern, Central and Western military districts were placed under its command in May. The IJN defensive fighter units stationed at 2118:. The first two of these attacks on 13 and 18 December used precision bombing tactics, and damaged the city's aircraft plants. The third raid was a daylight incendiary attack which was conducted after the Twentieth Air Force directed that 100 B-29s armed with M-69 bombs be dispatched against Nagoya to test the effectiveness of these weapons on a Japanese city. Hansell protested this order, as he believed that precision attacks were starting to produce results and moving to 2726: 2398: 2075:; this was the first American aircraft to fly over the city since the Doolittle Raid. Further F-13 sorties were conducted during early November to gather intelligence on aircraft factories and port facilities in the Tokyo–Yokosuka area. The F-13s were generally able to evade the heavy anti-aircraft fire they attracted and the large numbers of Japanese fighters that were scrambled to intercept them as they flew at both high speed and high altitude. 3118:

initially fiercely contested, from early July onwards they encountered little opposition as the Japanese aircraft were withdrawn so that they could be preserved for later operations. Between 1 and 13 July, the Americans flew 286 medium and heavy bomber sorties over Kyushu without loss. As the fighters met few Japanese aircraft, they were mainly used to attack transportation infrastructure and targets of opportunity; these included at least two

For instance, 33 American airmen were killed by IJA personnel at Fukuoka, including 15 who were beheaded shortly after the Japanese Government's intention to surrender was announced on 15 August. Mobs of civilians also killed several Allied airmen before the Japanese military arrived to take the men into custody. In addition to these killings, most captured B-29 crewmen were brutally interrogated by the Kempeitai. 2706:

kept copies of these leaflets. On the night of 27/28 July, six B-29s dropped leaflets over 11 Japanese cities warning that they would be attacked in the future; this was intended to lower the morale of Japanese civilians and convince them that the United States was seeking to minimize civilian casualties. As these cities were very weakly defended, the warnings did not increase the risks facing the American bomber forces. Six of the cities (

In the first of these raids 520 B-29s destroyed 5.3 square miles (14 km) of southern Tokyo with 17 aircraft lost and 69 damaged. The second attack involved 502 B-29s and destroyed 16.8 square miles (44 km) of the city's central area, including the headquarters of several key government ministries and much of the 1573:. These leaflets did not have any effect on Japanese civilians, but demonstrated that China could potentially conduct small scale air attacks on the area. The Japanese military later incorrectly concluded that the ROCAF had aircraft capable of mounting attacks at a range of 1,300 miles (2,100 km) from their bases, and took precautions against potential raids on western Japan when Chinese forces launched an offensive during 1939. 2510:; both facilities were badly damaged. A single group of Superfortresses also attempted to bomb a Kawasaki Aircraft Industries factory at Akashi but accidentally struck a nearby village instead. The next day, XXI Bomber Command bombers escorted by 107 P-51s successfully attacked six different factories in the Tokyo Bay region. Precision bombing raids were also conducted on 22 June, when 382 B-29s attacked six targets at Kure, 3049:, sinking an aircraft carrier, three battleships, two heavy cruisers, a light cruiser and several other warships. Most of the surviving large warships of the Japanese navy were sunk in this attack. A force of 79 USAAF Liberators flying from Okinawa participated in this attack on 28 July. Allied casualties in this operation were heavy, however, as 126 aircraft were shot down. On 29 and 30 July the carrier aircraft struck at 1905:

2011, the Osaka District Court handed down a similar ruling, adding that the government did not violate its constitution in its treatment of bombing victims. This judgement stated that there had not been "unreasonable disparity" in how civilians, soldiers, and atomic bomb survivors were treated, and that the government had showed "no gross deviation from its discretionary right in not legislating for redress measures".

The city was attacked again by 61 B-29s on 21 November and by 17 bombers on 19 December. XX Bomber Command made its ninth and final raid on Japan on 6 January 1945 when 28 B-29s once again struck Ōmura. During the same period the command conducted a number of attacks on targets in

operations and complicated the process of launching and recovering the bombers. By March 1945 the USAAF's commanders were highly concerned about the failure of the campaigns mounted from China and the Mariana Islands, and believed that the results to date made it difficult to justify the high costs of the B-29 program and also threatened their goal of demonstrating the effectiveness of independent air power.

3201:, but by this time the fighter force's effectiveness had been greatly reduced due to high rates of casualties in training accidents and combat. Due to the poor standard of the remaining pilots and the deployment of P-51 Mustangs to escort B-29s, the Japanese leadership decided in April to withdraw their remaining fighters from combat. These aircraft were placed in reserve to counterattack the anticipated 2099:, specifically developed to damage Japanese urban areas. The aircraft plant was attacked on 27 November and 3 December and was only lightly damaged as high winds and clouds prevented accurate bombing. The incendiary raid conducted on the night of 29/30 November by 29 Superfortresses burnt out one tenth of a square mile, and was also judged to be unsuccessful by the Twentieth Air Force's headquarters. 2263:—was carried out against Tokyo on the night of 9/10 March, and proved to be the single most destructive air raid of the war. XXI Bomber Command mounted a maximum effort, and on the afternoon of 9 March 346 B-29s left the Marianas bound for Tokyo. They began to arrive over the city at 2:00 am Guam time on 10 March, and 279 bombers dropped 1,665 tons of bombs. The raid caused a massive 1499:(IJN) fighter aircraft, many of which were obsolete, as well as 500 Army-manned and 200 IJN anti-aircraft guns. Most of the IJAAF and IJN formations in the home islands were training units which had only a limited ability to counter Allied attacks. The Army also operated a network of military and civilian observation posts to provide warning of air attack and was in the process of building 3239:. There was, however, no international treaty or instrument protecting a civilian population specifically from attack by aircraft at the time. As a result of the cabinet directions, captured Allied airmen were subject to trial and possible execution. The frequency of such executions differed between military districts, however. While no airmen were executed in the Tōbu district (eastern 2994:, including 70 out of the 272 small sailing ships which carried coal between the islands. Once again no Japanese aircraft opposed this attack, though 25 were destroyed on the ground. The loss of the train ferries reduced the amount of coal shipped from Hokkaido to Honshu by 80 percent, which greatly hindered production in Honshu's factories. Cities on Hokkaido such as Hakodate, 2373:

On 24 April the Tachikawa aircraft engine factory at Yamato near Tokyo was destroyed by 131 B-29s. An attack on the aircraft arsenal at Tachikawa six days later was aborted due to cloud cover; some of the heavy bombers attacked the city of

2164:. However, these attacks were frustrated by high winds and cloud cover and little damage was inflicted. A firebombing raid conducted against Tokyo by 172 B-29s on 25 February was considered successful as it burnt or damaged approximately one square mile of the city's urban area. This attack was a large-scale test of the effectiveness of firebombing. 1633:. The Japanese air defense units were taken by surprise, and all the B-25s escaped without serious damage. The aircraft then continued to China and the Soviet Union, though several crashed in Japanese-held territory after running out of fuel. Japanese casualties were 50 killed and over 400 wounded. About 200 houses were also destroyed. 2068:, who had also participated in Eighth Air Force operations against Germany. XXI Bomber Command B-29s flew six practice missions against targets in the Central Pacific during October and November in preparation for their first attack on Japan. On 1 November, an F-13 photo reconnaissance variant of the B-29 from the 2226:, was aware of the change in tactics though and provided support. The decision to use firebombing tactics represented a move away from the USAAF's previous focus on precision bombing, and was believed by senior officials in the military and US Government to be justified by the need to rapidly bring the war to an end. 2123:

In light of the poor results of the precision bombing campaign and the success of the 25 February raid on Tokyo, and considering that many tons of incendiaries were now available to him, LeMay decided to begin firebombing attacks on Japan's main cities during early March 1945. This was in line with

To maximize the effectiveness of the firebombing attacks, LeMay ordered the B-29s to fly at the low altitude of 5,000 feet (1,500 m) and bomb by night; this represented a significant change from the Command's standard tactics, which focused on high-altitude daylight bombing. As Japan's
