TheJapan Confederation of A- and H-Bomb Sufferers Organizations[a], often shortened toNihon Hidankyō (日本被団協,Nihon Hidankyō), is a group that represents survivors (known ashibakusha) of theatomic bombings of Hiroshima and Nagasaki. It was formed in 1956.
Nihon Hidankyōlobbies both the Japanese government for improved support of the victims and governments worldwide for theabolition of nuclear weapons.[1] Their activities included recording thousands of witness accounts, issuing resolutions and public appeals, and sending annual delegations to variousinternational organisations, including theUnited Nations, to advocate for global nuclear disarmament.[2]
The organisation was awarded the2024 Nobel Peace Prize "for its efforts to achieve a world free of nuclear weapons and for demonstrating through witness testimony that nuclear weapons must never be used again".[2][3]

Nihon Hidankyo is a nation-wide organisation formed by survivor groups of atomic bomb victims fromHiroshima and Nagasaki in eachprefecture.[4] The fallout fromCastle Bravo, a thermonuclear weapon test conducted atBikini Atoll by the United States in 1954, caused acute radiation syndrome in residents of neighbouring atolls and 23 crew members of the Japanese fishing vesselDaigo Fukuryū Maru. This led to the formation of theJapan Council against Atomic and Hydrogen Bombs in Hiroshima the following year.[5] Inspired and supported by this movement, atomic bomb survivors established Nihon Hidankyo on 10 August 1956, at the second annual conference of the council in Nagasaki.[6]
However, the movement's solidarity was jeopardised when the council became actively involved in theanti-U.S.-Japan Security Treaty movement alongside the left-leaningJapan Socialist Party in 1959.[7] A large number of supporters withdrew from the council, and with the support of the conservativeLiberal Democrats, a new organisation, led by Masatoshi Matsushita, leader of the staunchly anti-communistDemocratic Socialist Party, was established.[8] In 1961, when theSoviet Union resumed nuclear tests, the communist wing of the council refused to denounce them, which led to severe internal tension.[9] This led to a further split in the movement, with a Japan Socialist Party-backed group that denounces nuclear tests by any nation breaking away as a new council.[10] These tensions withinanti-nuclear movements caused some prefectural Hidankyos to split at the local level as well, such as in Hiroshima, where there are both Socialist Party-backed and Communist Party-backed Hidankyos with the same name. The nationwide organisation itself decided not to align with any political movements in 1965, after they became highly politicised.[4]
As of October 2024, Nihon Hidankyo's activities include:[11]
Advocacy for the abolition of nuclear weapons and demands for state compensations
Petitioning actions towards the Japanese government, the United Nations and other governments
Elimination and removal of nuclear weapons, establishment of an internationaltreaty for nuclear disarmament, holding of international conferences, enactment of non-nuclear laws and enhancement of hibakusha support measures
Raising awareness of the realities of the atomic bombings both domestically and internationally
Research, study, publication, exhibitions and gatherings on atomic bomb damage
