Survivors of atomic bombings in Japan From Wikipedia, the free encyclopedia
Hibakusha (pronounced [çibaꜜkɯ̥ɕa] or [çibakɯ̥ꜜɕa]; Japanese: 被爆者 or 被曝者; lit. 'survivor of the bomb' or 'person affected by exposure [to radioactivity]') is a word of Japanese origin generally designating the people affected by the atomic bombings of Hiroshima and Nagasaki by the United States at the end of World War II.
The word hibakusha is Japanese, originally written in kanji. While the term hibakusha 被爆者 (hi 被 'affected' + baku 爆 'bomb' + sha 者 'person') has been used before in Japanese to designate any victim of bombs, its worldwide democratization led to a definition concerning the survivors of the atomic bombs dropped in Japan by the United States Army Air Forces on 6 and 9 August 1945.
Anti-nuclear movements and associations, among others of hibakusha, spread the term to designate any direct victim of nuclear disaster, including the ones of the nuclear plant in Fukushima.[1] They, therefore, prefer the writing 被曝者 (replacing baku 爆 'bomb' with the homophonous 曝 'exposure') or 'person affected by the exposure", implying "person affected by nuclear exposure'.[2] This definition tends to be adopted since 2011.[3]
The legal status of hibakusha is allocated to certain people, mainly by the Japanese government.
The Atomic Bomb Survivors Relief Law defines hibakusha as people who fall into one or more of the following categories: within a few kilometers of the hypocenters of the bombs; within 2 km (1.2 mi) of the hypocenters within two weeks of the bombings; exposed to radiation from fallout; or not yet born but carried by pregnant women in any of the three previously mentioned categories.[4] The Japanese government has recognized about 650,000 people as hibakusha. As of 31 March 2024[update], 106,825 were still alive, mostly in Japan,[5] and in 2024 are expected to surpass the number of surviving US World War veterans.[6] The government of Japan recognizes about 1% of these as having illnesses caused by radiation.[7] Hibakusha are entitled to government support. They receive a certain amount of allowance per month, and the ones certified as suffering from bomb-related diseases receive a special medical allowance.[8]
The memorials in Hiroshima and Nagasaki contain lists of the names of the hibakusha who are known to have died since the bombings. Updated annually on the anniversaries of the bombings, as of August 2024[update], the memorials record the names of more than 540,000 hibakusha; 344,306 in Hiroshima[9] and 198,785 in Nagasaki.[10]
In 1957, the Japanese Parliament passed a law providing free medical care for hibakusha. During the 1970s, non-Japanese hibakusha who suffered from those atomic attacks began to demand the right to free medical care and the right to stay in Japan for that purpose. In 1978, the Japanese Supreme Court ruled that such persons were entitled to free medical care while staying in Japan.[11][12]
During the war, Korea had been under Japanese imperial rule, and many Koreans were forced to go to Hiroshima and Nagasaki as a labor force. According to recent estimates, about 20,000 Koreans were killed in Hiroshima and about 2,000 died in Nagasaki. It is estimated that one in seven of the Hiroshima victims was of Korean ancestry.[13] For many years, Koreans had a difficult time fighting for recognition as atomic bomb victims and were denied health benefits. However, most issues have been addressed in recent years through lawsuits.[14]
It was a common practice before the war for American Issei, or first-generation immigrants, to send their children on extended trips to Japan to study or visit relatives. More Japanese immigrated to the U.S. from Hiroshima than any other prefecture, and Nagasaki also sent many immigrants to Hawai'i and the mainland. There was, therefore, a sizable population of American-born Nisei and Kibei living in their parents' hometowns of Hiroshima and Nagasaki at the time of the atomic bombings. The actual number of Japanese Americans affected by the bombings is unknown – although estimates put approximately 11,000 in Hiroshima city alone – but some 3,000 of them are known to have survived and returned to the U.S. after the war.[15]
A second group of hibakusha counted among Japanese American survivors are those who came to the U.S. in a later wave of Japanese immigration during the 1950s and 1960s. Most in this group were born in Japan and migrated to the U.S. in search of educational and work opportunities that were scarce in post-war Japan. Many were war brides, or Japanese women who had married American men related to the U.S. military's occupation of Japan.[15]
As of 2014, there are about 1,000 recorded Japanese American hibakusha living in the United States. They receive monetary support from the Japanese government and biannual medical checkups with Hiroshima and Nagasaki doctors familiar with the particular concerns of atomic bomb survivors. The U.S. government provides no support to Japanese American hibakusha.[15]
While one British Commonwealth citizen[16][17][18][19][20] and seven Dutch POWs (two names known)[21] died in the Nagasaki bombing, at least two POWs reportedly died postwar from cancer thought to have been caused by the atomic bomb.[22][23] One American POW, the Navajo Joe Kieyoomia, was in Nagasaki at the time of the bombing but survived, reportedly having been shielded from the effects of the bomb by the concrete walls of his cell.[24]
People who suffered the effects of both bombings are known as nijū hibakusha in Japan. These people were in Hiroshima on 6 August 1945, and within two days managed to reach Nagasaki.
A documentary called Twice Bombed, Twice Survived: The Doubly Atomic Bombed of Hiroshima and Nagasaki was produced in 2006. The producers found 165 people who were victims of both bombings, and the production was screened at the United Nations.[25]
On 24 March 2009, the Japanese government officially recognized Tsutomu Yamaguchi (1916–2010) as a double hibakusha. Yamaguchi was confirmed to be 3 km (1.9 mi) from ground zero in Hiroshima on a business trip when the bomb was detonated. He was seriously burnt on his left side and spent the night in Hiroshima. He got back to his home city of Nagasaki on 8 August, a day before the bomb in Nagasaki was dropped, and he was exposed to residual radiation while searching for his relatives. He was the first officially recognized survivor of both bombings.[26] Yamaguchi died at the age of 93 on 4 January 2010 of stomach cancer.[27]
Hibakusha and their children were (and still are) victims of severe discrimination when it comes to prospects of marriage or work[28] due to public ignorance about the consequences of radiation sickness, with much of the public believing it to be hereditary or even contagious.[29][30] This is despite the fact that no statistically demonstrable increase of birth defects or congenital malformations was found among the later conceived children born to survivors of the nuclear weapons used at Hiroshima and Nagasaki, or found in the later conceived children of cancer survivors who had previously received radiotherapy.[31][32][33] The surviving women of Hiroshima and Nagasaki, who could conceive, and were exposed to substantial amounts of radiation, went on and had children with no higher incidence of abnormalities or birth defects than the rate observed in the Japanese population.[34][35]
Studs Terkel's book The Good War includes a conversation with two hibakusha. The postscript observes:
There is considerable discrimination in Japan against the hibakusha. It is frequently extended toward their children as well: socially as well as economically. "Not only hibakusha but their children, are refused employment," says Mr. Kito. "There are many among them who do not want it known that they are hibakusha."

The Japan Confederation of A- and H-Bomb Sufferers Organizations (日本被団協, Nihon Hidankyō) is a group formed by hibakusha in 1956 with the goals of pressuring the Japanese government to improve support of the victims and lobbying governments for the abolition of nuclear weapons.[37]
Some estimates are that 140,000 people in Hiroshima (38.9% of the population) and 70,000 people in Nagasaki (28.0% of the population) died in 1945, but how many died immediately as a result of exposure to the blast, heat, or due to radiation, is unknown. One Atomic Bomb Casualty Commission (ABCC) report discusses 6,882 people examined in Hiroshima, and 6,621 people examined in Nagasaki, who were largely within 2000 meters from the hypocenter, who suffered injuries from the blast and heat but died from complications frequently compounded by acute radiation syndrome (ARS), all within about 20–30 days.[38][39]
In the rare cases of survival for individuals who were in utero at the time of the bombing and yet who still were close enough to be exposed to less than or equal to 0.57 Gy, no difference in their cognitive abilities was found, suggesting a threshold dose for pregnancies below which there is no danger. In 50 or so children who survived the gestational process and were exposed to more than this dose, putting them within about 1000 meters from the hypocenter, microcephaly was observed; this is the only elevated birth defect issue observed in the hibakusha, occurring in approximately 50 in-utero individuals who were situated less than 1000 meters from the bombings.[40][41]
In a manner dependent on their distance from the hypocenter, in the 1987 Life Span Study, conducted by the Radiation Effects Research Foundation, a statistical excess of 507 cancers, of undefined lethality, were observed in 79,972 hibakusha who had still been living between 1958–1987 and who took part in the study.[42]
An epidemiology study by the RERF estimates that from 1950 to 2000, 46% of leukemia deaths and 11% of solid cancers, of unspecified lethality, could be due to radiation from the bombs, with the statistical excess being estimated at 200 leukemia deaths and 1,700 solid cancers of undeclared lethality.[43]
