How close did the Aum cult come to getting a nuclear bomb?

Japan Today14-05-2025
On March 20 this year, people in Tokyo observed the 30th anniversary of the doomsday cult Aum Supreme Truth's nerve gas attack on the Tokyo subway system.
Writing in Shukan Shincho (May 15), reporter Koji Kiyota relates the Aum's activities in the summer of 1993, the same year the cult succeeded in producing sarin, a toxic nerve gas formulated by German scientists at IG Farben in 1938.
Aum guru Shoko Asahara (aka Chizuo Matsumoto) had allegedly exhorted his minions to manufacture 70 tons of the substance, which in theory would have been sufficient to kill all 7 billion people (at the time) inhabiting the planet. As one means to this end, the cult had already procured a large military helicopter from the former Soviet Union.
It was also revealed that Asahara had directed the cult's scientists to research development of nuclear weapons.
A key figure in the cult's efforts to build up its military arsenal was Naruto Noda, a member of Aum's "Ministry of Science and Technology" then headed by Hideo Murai.
"Around the start of 1993, discussions began about the possibility of developing a nuclear weapon," related Noda, who completely broke off ties with the cult in 2009. "At first Asahara just asked us to look into it, but it was clear that he was serious about producing one."
Ten years ago, Noda had spoken on the record about how a contingent of 20 high-ranking Aum members, including Asahara, traveled to Australia to look into mining uranium and developing a nuclear weapon. Kiyota finally followed up with a trip to Western Australia, where he met Mick Palmer, a former federal police official involved in the investigation.
Palmer recalled the kerfuffle that transpired when the Aum contingent arrived at Perth airport.
"We had been contacted following an incident at customs, but at that time we had no idea at all what Aum was," said Palmer. "They'd stated the purpose of their visit was tourism"
For tourists, the Aum contingent were certainly carrying some bizarre items. Among them were containers labeled "hand soap" that upon testing were found to contain concentrated hydrochoric acid.
Also among their possessions were an electric power generator and two excavation machines packed in containers measuring two meters square.
The cultists were judged to be in violation of a number of customs restrictions and fined A$4,800.
It was later learned that Asahara's group had chartered two light aircraft and set out for Banjarwan Station, in Australia's remote interior about 700 kilometers northeast of Perth, where the cult had paid out the equivalent of 24 million Japanese yen to purchase a ranch.
The former owner of the ranch, Neil White, drove reporter Kiyota to a location about 20 minutes from the airfield, where he pointed out remnants of the cult's presence, including a depression in the ground measuring three meters in diameter and one meter deep.
According to White, a number of foreign firms had previously conducted exploration for high-grade uranium ore in the area, and it appears that Aum's scientists had also undertaken serious efforts to do so.
At the entrance to the ranch, a sign warns of danger. A one-story building, probably used to house construction workers, still stands. A video filmed back in 1995 showed a sign on the door that read "Toyoda Laboratory" -- so named after Aum scientist Toru Toyoda, a former graduate student of physics at the elite University of Tokyo.
"Before the cultists left, they dug a large hole to conceal any evidence," David Parkinson, a state police official assigned to counterterrorism, tells the reporter. "It appears that glass fragments found therein had been subjected to extremely high temperatures."
Was Parkinson describing something similar to trinitite, the glassy greenish residue left on the desert floor after the Trinity nuclear bomb test in July 1945, near Alamogordo, New Mexico? Alas, the writer doesn't say one way or the other.
Also found on the ranch were numerous sheep carcasses, which forensic tests revealed had been exposed to sarin. Unfortunately these revelations did not surface until Aum members released sarin with fatal results in Matsumoto, Nagano Prefecture in June 1994 and on a larger scale in Tokyo in March 1995.
"At that time, if proactive measures had been taken, the gassings might have been prevented," says Shizue Takahashi, whose husband Kazumasa, the assistant stationmaster at Kasumigaseki Station, was among the 14 killed in the March 1995 subway attack.
Over 6,000 people were said to have been sickened to varying degrees by the gas, but because the day of the attack, March 20, was a Monday sandwiched between a weekend and a national holiday, subway commuters were fewer than usual -- otherwise the number of casualties would almost certainly have been higher.
"People often say that the incident is fading from memory," Takahashi tells the magazine. "I've heard that to my face, but I feel like saying, 'So what?' People's memories will fade. But the legal team representing the victims are still fighting Aum's successor groups.
"The emotional wounds and pain of the bereaved families and victims will never heal," Takahashi continues, adding, "The matter of compensation payments to the victims by Aum's successor groups, amounting to about 1 billion yen, remains unresolved."

Koizumi urges South Korea to lift import ban on Japanese seafood

South Korean Foreign Minister Cho Hyun, right, meets with farm minister Shinjiro Koizumi on Aug. 11 in Seoul. (Daisuke Shimizu) SEOUL--Fisheries minister Shinjiro Koizumi called on South Korea to lift import restrictions on Japanese seafood products that were imposed following the 2011 Fukushima nuclear disaster. He made the call during an Aug. 11 meeting here with Foreign Minister Cho Hyun. Seoul slapped curbs on imports over fears fish caught in the Pacific could be contaminated with radiation due to the triple meltdown at the Fukushima No. 1 nuclear plant. After the meeting, Koizumi told reporters that trust in the safety of Japanese food products has revived. He expressed strong hopes for swift progress in dialogue between the two countries toward removing the restrictions. 'If we proceed based on sound science, mutual understanding can certainly be achieved,' he said. Import controls remain in effect for marine products from eight prefectures, including Fukushima and Miyagi. While Koizumi did not disclose South Korea's immediate response to his request, he emphasized the symbolic importance of Japan's fisheries minister meeting with the country's foreign minister. 'This meeting itself is a reflection of their message to promote and develop our bilateral relations,' he said. In Seoul, the Foreign Ministry said the two ministers emphasized the importance of close communication. They also exchanged views on broader bilateral relations, including economic cooperation, officials added. Cho stressed the need for more active dialogue at all levels to build stronger and more mature bilateral ties, especially as the two countries mark the 60th anniversary of the normalization of diplomatic relations. Koizumi was in South Korea to attend an APEC ministerial meeting on food security, as well as a trilateral agriculture ministers' meeting with China and South Korea.

China says it handles entry into territorial waters based on laws

BEIJING (Kyodo) -- China said Monday evening it handles the unauthorized entry into its territorial waters by foreign military vessels "in accordance with the laws," following reports that Chinese ships fired at least two warning shots at a Japanese destroyer in July last year. Chinese Foreign Ministry spokesman Lin Jian said in a statement that foreign military vessels "must obtain approval" from the Chinese government before entering the country's territorial waters, without confirming whether the warning shots had been fired. According to diplomatic sources, the warning shots did not hit the Suzutsuki of the Japanese Maritime Self-Defense Force when it inadvertently entered Chinese territorial waters off the country's eastern province of Zhejiang on July 4, 2024, despite repeated warnings. The destroyer, which was tasked with monitoring Chinese military drills on the high seas, sailed for some 20 minutes in Chinese waters, within 12 nautical miles (22 kilometers) of the Zhejiang coast. The incident triggered a protest from Beijing that urged Tokyo to prevent a similar case in the future. Chinese domestic law requires foreign vessels to seek prior permission before entering the country's waters. But Tokyo maintains that the Suzutsuki's entry into Chinese territorial waters was not illegal, citing the right to innocent passage. The U.N. Convention on the Law of the Sea recognizes the right to allow for a vessel to pass through the territorial waters of another state unless it compromises the safety of the coastal state.

US and China Extend Trade Truce Another 90 Days, Easing Tension between World's Largest Economies

WASHINGTON (AP) — President Donald Trump extended a trade truce with China for another 90 days Monday, at least delaying once again a dangerous showdown between the world's two biggest economies. Trump posted on his Truth Social platform that he signed the executive order for the extension, and that 'all other elements of the Agreement will remain the same.' Beijing at the same time also announced the extension of the tariff pause via the official news agency Xinhua. The previous deadline was set to expire at 12:01 a.m. Tuesday. Had that happened the U.S. could have ratcheted up taxes on Chinese imports from an already high 30%, and Beijing could have responded by raising retaliatory levies on U.S. exports to China. The pause buys time for the two countries to work out some of their differences, perhaps clearing the way for a summit later this year between Trump and Chinese President Xi Jinping, and it has been welcomed by the U.S. companies doing business with China. Sean Stein, president of the U.S.-China Business Council, said the extension is 'critical' to give the two governments time to negotiate a trade agreement that U.S. businesses hope would improve their market access in China and provide the certainty needed for companies to make medium- and long-term plans. 'Securing an agreement on fentanyl that leads to a reduction in U.S. tariffs and a rollback of China's retaliatory measures is acutely needed to restart U.S. agriculture and energy exports,' Stein said. Reaching a pact with China remains unfinished business for Trump, who has already upended the global trading system by slapping double-digit taxes – tariffs – on almost every country on earth. The European Union, Japan and other trading partners agreed to lopsided trade deals with Trump, accepting once unthinkably U.S. high tariffs (15% on Japanese and EU imports, for instance) to ward off something worse. Trump's trade policies have turned the United States from one of the most open economies in the world into a protectionist fortress. The average U.S. tariff has gone from around 2.5% at the start of the year to 18.6%, highest since 1933, according to the Budget Lab at Yale University. But China tested the limits of a U.S. trade policy built around using tariffs as a cudgel to beat concessions out of trading partners. Beijing had a cudgel of its own: cutting off or slowing access to its rare earths minerals and magnets – used in everything from electric vehicles to jet engines. In June, the two countries reached an agreement to ease tensions. The United States said it would pull back export restrictions on computer chip technology and ethane, a feedstock in petrochemical production. And China agreed to make it easier for U.S. firms to get access to rare earths. 'The U.S. has realized it does not have the upper hand,'' said Claire Reade, senior counsel at Arnold & Porter and former assistant U.S. trade representative for China affairs. In May, the U.S. and China had averted an economic catastrophe by reducing massive tariffs they'd slapped on each other's products, which had reached as high as 145% against China and 125% against the U.S. Those triple-digit tariffs threatened to effectively end trade between the United States and China and caused a frightening sell-off in financial markets. In a May meeting in Geneva they agreed to back off and keep talking: America's tariffs went back down to a still-high 30% and China's to 10%. Having demonstrated their ability to hurt each other, they've been talking ever since. 'By overestimating the ability of steep tariffs to induce economic concessions from China, the Trump administration has not only underscored the limits of unilateral U.S. leverage, but also given Beijing grounds for believing that it can indefinitely enjoy the upper hand in subsequent talks with Washington by threatening to curtail rare earth exports,' said Ali Wyne, a specialist in U.S.-China relations at the International Crisis Group. 'The administration's desire for a trade détente stems from the self-inflicted consequences of its earlier hubris.' It's unclear whether Washington and Beijing can reach a grand bargain over America's biggest grievances. Among these are lax Chinese protection of intellectual property rights and Beijing's subsidies and other industrial policies that, the Americans say, give Chinese firms an unfair advantage in world markets and have contributed to a massive U.S. trade deficit with China of $262 billion last year. Reade doesn't expect much beyond limited agreements such as the Chinese saying they will buy more American soybeans and promising to do more to stop the flow of chemicals used to make fentanyl and to allow the continued flow of rare-earth magnets. But the tougher issues will likely linger, and 'the trade war will continue grinding ahead for years into the future,'' said Jeff Moon, a former U.S. diplomat and trade official who now runs the China Moon Strategies consultancy.
