In the 1960s and in the latter decades of the 20th century, Gensuikyo has teamed up with protest movements in Australia, New Zealand and elsewhere to protest against French nuclear weapons in the Pacific.
Since 2000 Gensuikyo has been a vocal and active member of worldwide civil society movements putting pressure on the nuclear-armed states to engage in genuine nuclear disarmament. Japan, with Gensuikyo at the forefront, sent between 800 and 1,000 representatives to the UN, on the occasion of the NPT preliminary conferences and then the NPT Revision conferences themselves.
Those meetings revealed the duplicity of the nuclear armed states, with their repeated promises to engage in genuine disarmament in line with their commitments under Article 6 of the NPT, and their repeated and ongoing failure to honour, even to begin to honour, the said promises and commitments.
Gensuikyo continues to participate in the NPT revision conferences, but along with other civil society movements, it is increasingly focusing its energies on promoting the Treaty on the Prohibition of Nuclear Weapons. While maintaining active international links, its priority in this regard is to raise awareness in Japan itself. As the only country ever to have suffered a nuclear attack, and as -regarding civil society at least- an independent voice in a world where superpowers try to pressure allies into subservience, Japan ought to be fertile territory for support for the TPNW.
In practice things are not so simple. Although weaker than it was, and despite the unpopularity of its leader, Prime Minister Abe, the Liberal Democratic party seems certain to be re-elected in elections due later this year. Japanese society as a whole is politically and socially conservative, and apathy or ignorance of the nuclear threat, even in this nuclear-victim country, are prevalent here as they are elsewhere.
Despite this, there are signs of hope. In November 2019 Pope Francis II visited Hiroshima and Nagasaki, and made rousing speeches calling out nuclear weapons for the monstrous abomination they are. Further to his visit, opinion polls showed 65.9% of Japanese supporting signature of the TPNW by Japan; 10 million people have signed a petition, and 448 local councils – out of a total or 1700 – have passed resolutions, calling on Japan to sign. At a national level, though divided, the main opposition parties are also favourable.
