TOKYO — Japan, the only country to have suffered atomic bomb attacks, has repeatedly called for a global ban on nuclear weapons. Yet it sided with the nuclear powers and NATO in refusing to sign a treaty to ban such weapons during the U.N. General Assembly meeting in New York.
The treaty, the first of its kind, was signed Wednesday by 50 countries, just enough for it to take effect. The signatories are barred from developing, testing, producing, acquiring, possessing or stockpiling nuclear weapons.
Here’s a look at what’s behind Japan’s reasoning:
TOKYO UNDER U.S. NUCLEAR UMBRELLA
Japan, as a close U.S. ally, is protected by America’s extended nuclear deterrence, or “nuclear umbrella,” even though Tokyo renounces its own possession, production or entry of nuclear weapons on its turf. That makes it difficult for Tokyo to sign the treaty especially as it steps up its military role amid North Korea’s missile and nuclear threats. Under Prime Minister Shinzo Abe’s hawkish government, the two countries have stepped up bilateral security cooperation. Besides Japan, most U.S. allies — almost all NATO members, South Korea and Australia — also did not participate in the talks on the treaty.
A TREATY LONG PURSUED BY HIBAKUSHA
Most atomic bombing survivors, or “hibakusha,” have made lifetime devotion to achieving a nuclear-free world, and their decades-long steady effort has been regarded as a driving force for that cause. Hiroshima atomic bomb survivor Toshiki Fujimori, a leader of Japan’s main group for the survivors, says nuclear weapons are absolutely “incompatible” with humans, and the treaty is a first step. He says Japan should sign, and its refusal to do so broke the hearts of many survivors, including his own. During the Aug. 9 memorial service in Nagasaki, the city’s outspoken Mayor Tomihisa Taue criticized Abe’s government for not joining the treaty, accusing it of making empty promises about achieving a nuclear-free world. He said Japan’s absence is “incomprehensible” especially to those in Hiroshima and Nagasaki, where the two U.S. attacks in August 1945 killed more than 210,000 people by the end of that year.
