U.S. urges clarity on Japan's role in potential war over Taiwan, report says
U.S. Undersecretary of Defense for Policy Elbridge Colby has been broaching the sensitive issue in meetings with Japanese and Australian officials in recent months, the Financial Times (FT) quoted unidentified sources as saying.
Following the report's publication, Colby said in a post to X that linked to the report that the Defense Department is focused on implementing U.S. President Donald Trump's 'America First' agenda of 'restoring deterrence and achieving peace through strength.' He said that included 'urging allies to step up their defense spending and other efforts related to our collective defense.'
Quoting an unidentified U.S. defense official, the FT said the 'animating theme' of the discussions with allies was 'to intensify and accelerate efforts to strengthen deterrence in a balanced, equitable way.'
But the move reportedly caught Japanese officials off-guard since the U.S. itself maintains a policy of 'strategic ambiguity' on whether or not it would defend democratic Taiwan. China claims the self-ruled island as its own and has vowed to unify it with the mainland, by force if necessary.
Colby hinted in his post on X that moves by the Pentagon under Trump had caused unease among some U.S. partners, but emphasized that the U.S. side 'will not be deterred from advancing his agenda.'
'Of course, some among our allies might not welcome frank conversations,' he wrote. 'But many ... are seeing the urgent need to step up and are doing so.'

Asked to confirm the report, the Pentagon referred The Japan Times to Colby's X post and one by chief Pentagon spokesman Sean Parnell quoting a media commentator praising the FT story.
'The Department of Defense is focused on preventing war, with a strong shield of deterrence,' Parnell said in quoting the commentator. 'That requires strength — but it is a simple fact that our allies must also do their part.'
Washington is Taiwan's most important global backer and arms supplier — despite not having formal diplomatic ties with Taipei. Trump has refused to say what he would do in the event of a Taiwan emergency, differing from his predecessor, Joe Biden, who deviated from U.S. policy several times by hinting that the United States would defend the island.
Tokyo, which also does not have diplomatic ties with Taipei, has also become more vocal about its concerns over Taiwan in recent years. The Chinese military has ramped-up training and drills near the island, unnerving Japan and prompting senior government and ruling party officials to say that an emergency over Taiwan would also represent an emergency for Japan.
Those fears are widely seen as a driving factor behind Japan's push to beef up its defense capabilities, with Tokyo saying in a defense white paper last year that China's string of large-scale military exercises around Taiwan likely 'demonstrated at least part of Beijing's invasion strategy.'
Japan in March unveiled an evacuation plan for the roughly 120,000 people on remote southwestern islands near Taiwan, drawn up with a possible conflict in mind.

The U.S. and Japan are also widely believed to be working on concrete operation plans in the event of an emergency over Taiwan. Recent bilateral and trilateral military drills involving the U.S., Japan and Australia — including this month's Southern Jackaroo and Talisman Sabre exercises — are largely focused on interoperability with a Taiwan contingency in mind.
But any military response by Japan would face constitutional and legal restraints, though these have been loosened over the last decade. Much would also depend heavily on whether China struck U.S. or Self-Defense Force bases in Japan.
Japanese leaders would have to formally declare such a contingency as being at a certain level to allow the SDF to respond. That process would likely take some time to unfold — a likely concern of Washington — although the severity of the situation could quicken decision-making.
Experts say that in the event of a Taiwan contingency, time would be of the essence when making critical policy decisions.
'The allies should avoid, at all costs, a situation in which the U.S. is engaged in the defense of Taiwan while Tokyo debates its response,' James J. Przystup, a senior fellow with the Hudson Institute think tank, wrote in an analysis released Thursday.
'Failure to respond in a timely fashion would put the alliance at risk,' he added.

Upper House election could further hamper BOJ's drive to raise rates
Japan's central bank may face political pressure to keep interest rates low for longer than it wants, as opposition parties favoring tax cuts and loose monetary policy are expected to gain influence after a July 20 election. Opinion surveys suggest Prime Minister Shigeru Ishiba's coalition may lose its majority in the Upper House of parliament, forcing it to court an array of smaller parties pushing for easier fiscal and monetary policy. The governing bloc led by Ishiba's Liberal Democratic Party is already a minority in the more powerful Lower House, so a stalemate in both chambers could give opposition parties outsized influence in policy decisions. Ishiba has supported the Bank of Japan's policy of gradually lifting interest rates from near zero as inflation picks up in the world's fourth-biggest economy, while trying to curb the biggest government debt burden in the industrial world. But if opposition groups gain traction with their pressure on the BOJ to avoid rate hikes and for the government to cut the sales tax, that could boost bond yields and complicate the bank's efforts to normalize monetary policy, some analysts say. The BOJ declined to comment on the potential impact of the election on monetary policy. "There's a 50% chance the ruling coalition could lose its majority in the Upper House, which could lead to increased debate about cutting Japan's consumption tax rate," said Daiju Aoki, chief Japan economist at UBS SuMi Trust Wealth Management. "That would push up Japan's long-term interest rates by stoking concern over the country's finances," he said. Sohei Kamiya, head of the upstart right-leaning party Sanseito, has criticized the BOJ for slowing its bond buying when the economy remains weak. "The Finance Ministry and BOJ should work hand in hand in taking aggressive steps for a few years to boost domestic demand," Kamiya told a news conference this month. Another opposition party, Nippon Ishin no Kai, wants the BOJ to go slow in raising rates to restrain the cost of interest on the government's debt. Yuichiro Tamaki, head of the Democratic Party for the People, a party seen as a strong candidate to join Ishiba's coalition, has urged the BOJ to loosen, not tighten, monetary policy to keep the yen from rising and hurting the export-reliant economy. Even if the coalition keeps its majority, Ishiba may need to ditch his hawkish fiscal tilt and boost spending to cushion the economic blow from threatened U.S. tariffs and rising costs of living. "There's a good chance the government will compile an extra budget to fund another spending package to the tune of ¥5 trillion to ¥10 trillion ($35 billion to $70 billion). That would push up bond yields further," said former BOJ board member Makoto Sakurai, who expects the central bank to avoid raising rates at least until March. Japan's public debt is equal to 250% of gross domestic product, far above that of Greece at 165%. The government spends nearly a quarter of its budget to finance a ¥1,164 trillion debt pile, with the cost expected to rise steadily as the BOJ exits zero-interest rates. To be sure, inflation — above the BOJ's 2% target for three years — boosts nominal tax revenues, which can help the government avoid ramping up bond issuance to fund further spending. But cutting the consumption tax rate, an idea Ishiba has ruled out for now, would leave a bigger hole in Japan's finances. Once a fringe idea, cutting the 10% sales tax is now among Japan's most popular economic policy proposals. In a recent poll by the Asahi Shimbun 68% of voters thought a sales tax cut was the best way to cushion the blow from rising living costs, compared with 18% who preferred cash payouts. If the sales tax is on the chopping block after the election, it is the kind of vital issue that could prod Ishiba to dissolve the Lower House and call a snap election — a move that would prolong political uncertainty. If Ishiba were to step down, an LDP race to replace him could revive market attention to candidates like Sanae Takaichi, an advocate of aggressive monetary easing whom Ishiba narrowly beat in the party's leadership race last year. Unlike Ishiba, who gave a quiet nod to BOJ policy normalization, Takaichi has said it would be "stupid" for the central bank to raise rates. All this would mean the BOJ's rate hikes, already on pause due to uncertainty over U.S. tariffs, could be put on hold even longer. "We may need to brace for a long period of political uncertainty and market volatility," said Naomi Muguruma, chief bond strategist at Mitsubishi UFJ Morgan Stanley Securities. "That would just give the BOJ another reason to sit on the sidelines and wait for the dust to settle."

North Korea blasts Japan-US-South Korea joint aerial exercise
North Korea's defense ministry has lashed out at a recent joint aerial exercise staged by Japan, the United States and South Korea. The chief of the ministry's Policy Office issued a press statement through the state-run Korean Central News Agency, or KCNA, on Sunday. The statement expresses "serious concern" over what it calls the three countries' "hostile acts of persistently conducting provocative and threatening military actions." It also "strongly" warns of what it describes as "grave consequences to be entailed by them on the regional situation." The statement underscores that North Korea "will never tolerate any slightest act which exerts a negative influence on the security environment of the state." It also showed the country's readiness to take what it terms a "practical military counteraction." The trilateral exercise took place on Friday off the coast of a southern part of South Korea to deal with North Korea's nuclear and missile threats. It involved at least one US B-52 strategic bomber. The top uniformed defense officials of Japan, the US and South Korea also met in Seoul the same day. They reaffirmed cooperation to address challenges posed by North Korea.
