Bombing of Tokyo



The bombing of Tokyo by the United States Army Air Forces took place during the Pacific campaigns of World War II. The U.S. mounted a small-scale raid on Tokyo in April 1942, with larger morale effects. Strategic bombing and urban area bombing began in 1944 after the long-range B-29 Super Fortress bomber entered service, first employed from China and thereafter the Mariana Islands. B-29 raids from those islands commenced on November 17, 1944 and lasted until August 15, 1945, the day Japan capitulated. The air raid of 9-10 March 1945 was one of the most destructive bombing raids in history.

Doolittle Raid


The first raid on Tokyo was the Doolittle Raid of 18 April 1942, when sixteen B-25 Mitchells were launched from USS Hornet to attack targets including Yokohama and Tokyo and then fly on to airfields in China. The raid was the retaliation against the Japanese attack on Pearl Harbor. The raid did no damage to Japan's war capability but was a significant propaganda victory for the United States. Launched prematurely, none of the attacking aircraft reached the designated airfields, either crashing or ditching (except for one aircraft which landed in the Soviet Union, where the crew was officially interned and secretly repatriated). Two crews were captured by the Japanese in occupied China.

B-29 raids


The key development for the bombing of Japan was the B-29 bomber plane, which had an operational range of 3,250 nautical miles (6,019 km); almost 90% of the bombs dropped on the home islands of Japan were delivered by this type of bomber. Once Allied ground forces had captured islands sufficiently close to Japan, airfields were built on those islands (particularly Saipan and Tinian) and B-29s could reach Japan for bombing missions.

The initial raids were carried out by the Twentieth Air Force operating out of mainland China in Operation Matterhorn under XX Bomber Command, but these could not reach Tokyo. Operations from the Northern Mariana Islands commenced in November 1944 after the XXI Bomber Command was activated there. The B-29s of XX Bomber Command were transferred to XXI Bomber Command in the spring of 1945 and based on Guam.

The first raid using low-flying B-29s carrying incendiary bombs to drop on Tokyo was in February 1945 when 174 B-29s destroyed around one square mile (3 km²) of the city. Changing their tactics to expand the coverage and increase the damage, 335 B-29s took off to raid on the night of 9–10 March, with 279 of them dropping around 1,700 tons of bombs. Fourteen B-29s were lost. Approximately 16 square miles (41 km²) of the city were destroyed and some 100,000 people are estimated to have died in the resulting firestorm, more than the immediate deaths of either the Hiroshima or Nagasaki atomic bombs. The US Strategic Bombing Survey later estimated that nearly 88,000 people died in this one raid, 41,000 were injured, and over a million residents lost their homes. The Tokyo Fire Department estimated a higher toll: 97,000 killed and 125,000 wounded. The Tokyo Metropolitan Police Department established a figure of 124,711 casualties including both killed and wounded and 286,358 buildings and homes destroyed. Richard Rhodes, historian, put deaths at over 100,000, injuries at a million and homeless residents at a million. These casualty and damage figures could be low; Mark Selden wrote in Japan Focus:

"The figure of roughly 100,000 deaths, provided by Japanese and American authorities, both of whom may have had reasons of their own for minimizing the death toll, seems to me arguably low in light of population density, wind conditions, and survivors' accounts. With an average of 103,000 inhabitants per square mile (396 people per hectare) and peak levels as high as 135,000 per square mile (521 people per hectare), the highest density of any industrial city in the world, and with firefighting measures ludicrously inadequate to the task, 15.8 sqmi of Tokyo were destroyed on a night when fierce winds whipped the flames and walls of fire blocked tens of thousands fleeing for their lives. An estimated 1.5 million people lived in the burned out areas."

The destruction and damage were greatest in the parts of the city to the east of the Imperial Palace. Over 50% of Tokyo was destroyed by the end of World War II.

Other attacks
Additional missions against Tokyo targets were carried out by twin-engine bombers and by fighter-bombers.

Aftermath
Damage to Tokyo's heavy industry was slight until firebombing destroyed much of the light industry that was used as an integral source for small machine parts and time-intensive processes. Firebombing also killed or made homeless many workers who had been taking part in war industry. Over 50% of Tokyo's industry was spread out among residential and commercial neighborhoods; firebombing cut the whole city's output in half.

The Imperial Palace was surrounded by areas destroyed by firebombing. The main Palace itself (Kyūden), home of the Imperial General Headquarters, took heavy damage by fire, even though bombing it was specifically prohibited by USAAF order.

Emperor Hirohito's viewing of the destroyed areas of Tokyo in March, 1945, is said to have been the beginning of his personal involvement in the peace process, culminating in Japan's surrender five months later.

After the war, Tokyo struggled to rebuild. In 1945/1946, the city received a share of the national reconstruction budget roughly proportional to its amount of bombing damage (26.6%), but in successive years Tokyo saw its share dwindle. By 1949, Tokyo was given only 10.9% of the budget; at the same time there was runaway inflation devaluing the money as Japan was spending more than it was bringing in from taxes. Occupation authorities such as Joseph Dodge stepped in and drastically cut back on Japanese government rebuilding programs, focusing instead on simply improving roads and transportation. Tokyo did not experience fast economic growth until the 1950s.
