Japan warns of China's military moves as biggest strategic challenge
By Mari Yamaguchi
Japan raised strong caution against China's rapid acceleration of military activity in extensive areas from its southwestern coasts to the Pacific, describing the moves as the biggest strategic challenge.
China's growing joint operations with Russia also pose serious security concerns to Japan, along with increasing tension around Taiwan and threats coming from North Korea, the Defense Ministry said in an annual military report submitted to Cabinet on Tuesday.
'The international society is in a new crisis era as it faces the biggest challenges since the end of World War II,' the report said, citing significant changes to the global power balance while raising concerns about an escalation of the China-U.S. rivalry.
The security threats are concentrated in the Indo-Pacific, where Japan is located, and could get worse in the future, the report said.
Japan has accelerated its military buildup on southwestern islands in recent years, preparing to deploy long-distance cruise missiles, as it worries about a conflict in Taiwan, which China claims as its territory to be annexed by force if necessary. Taiwan launched 10-day, annual live-fire military exercises last week intended to guard against Chinese threats to invade. Japan tested a short-range, surface-to-ship missile at home earlier last month.
Chinese warships' advance in the Pacific has steadily increased, with the frequency of their passage off southwestern Japan tripling in the past three years, including in waters between Taiwan and its neighboring Japanese island of Yonaguni, the 534-page report said.
The report comes days after Japan demanded China stop flying its fighter jets abnormally close to Japanese intelligence-gathering aircraft, which it said was happening repeatedly and could cause a collision. Beijing, in return, accused Japan of flying near Chinese airspace for spying purposes.
Two earlier close encounters in June occurred over the Pacific Ocean, where Japan spotted two Chinese aircraft carriers operating together for the first time.
China's increasing dispatch of aircraft carriers in the Pacific underscores the country's attempt to advance its sea power in distant waters, the report said. It said China's frequent dispatch of bombers for long-distance flights in the Pacific by more sophisticated flight routes and fleet organization is seen as Beijing's attempt to show off its presence around Japan and to further advance its operational capability.
The Defense Ministry noted two cases last year — a Chinese warplane's brief violation of Japanese airspace over waters off islands near Nagasaki and an aircraft carrier's entry into a zone just outside of Japan's territorial waters further southwest of the Nansei island chain, which stretches from the southern coast of Kyushu to Taiwan.
With President Donald Trump focusing on the strengthening of the U.S. economy and security, Japan and other U.S. allies face expectations to play a greater role for peace and stability in the region, the report said.
North Korea poses 'an increasingly serious and imminent threat' for Japan's security, the report said, noting the North's development of missiles capable of carrying nuclear warheads into Japanese territory and solid-fuel intercontinental ballistic missiles that can reach the U.S. mainland.
Russia maintains active military operations around Japan and violated the country's airspace in September, the report added, saying its increasing strategic cooperation with China has posed 'strong concern' for Japan's security.

Opinion: Ishiba skipping NATO summit exposes gaps in Japan's Europe engagement
By Sayuri Romei and Alice Dell'Era WASHINGTON (Kyodo) -- Since a Japanese prime minister first attended a NATO summit in 2022, Japan has sent its highest-level representative to the event for three consecutive years. Russia's full-scale invasion of Ukraine in February 2022 was a key catalyst for Tokyo's decision to attend that year, and the 2025 summit in The Hague would have marked the fourth consecutive appearance by a Japanese leader. Prime Minister Shigeru Ishiba was expected to meet with like-minded NATO partners to deepen cooperation amid the security challenges that link the Euro-Atlantic and Indo-Pacific theaters. However, his participation was abruptly canceled, with Foreign Minister Takeshi Iwaya attending in his place. The decision not to attend personally represents a missed opportunity to strengthen ties with Europe at a time when Japan's strategic thinking is increasingly turning toward this region. Ishiba's glaring absence comes at a sensitive moment for Japan, as it confronts growing Chinese assertiveness while managing a more unpredictable United States. While previous U.S. administrations invested significant diplomatic and political capital in promoting cross-regional cooperation between NATO and its Indo-Pacific Four (IP4) partners, the current Trump administration has shown far less interest in advancing such efforts. In fact, President Donald Trump announced he would not attend a meeting between NATO and the IP4 partners during the summit in The Hague -- a move that likely prompted three of the four Indo-Pacific countries to cancel their leaders' attendance. Trump's emphasis on narrow, transactional negotiations over defense spending within allies' respective regions has broken the momentum for cross-regional cooperation built over the past three years. In this context, Ishiba's decision to skip the summit reflects Tokyo's desire to avoid confrontation with Trump over contentious issues such as defense expenditures and trade. These topics remain especially sensitive given the Japanese government's fragile approval ratings and the upcoming upper house elections in July. Ishiba's absence may have been an effort to preserve strategic flexibility in an increasingly unpredictable environment, but it risks halting the progress that Tokyo is making in advancing defense industrial ties with European NATO partners at a critical juncture. As geopolitical competition intensifies, defense technology innovation and a robust defense industrial base have emerged as indispensable strategic assets. Yet, this is an area where Japan has traditionally lagged, due to the longstanding constraints on its defense industry and heavy reliance on U.S. procurements. The tide, however, appears to be shifting. In its 2022 strategic documents, Tokyo identified reinforcing its defense production and technology base as a national priority. Since 2023, Japan has eased its export controls, allowing the licensed export of domestically produced defense equipment, including lethal systems, to boost competitiveness through economies of scale and access to overseas markets. At the same time, Tokyo seeks to diversify its defense procurement and development partnerships beyond the United States, increasingly turning towards European partners. As Japan carefully balances its security and economic relations with its ally, concerns over U.S. unpredictability have indeed elevated the importance of European partners for Tokyo's foreign and defense policy. Europe now features prominently in Japanese strategic thinking, with Tokyo expanding security cooperation with several European states at the bilateral and multilateral levels, through mechanisms like NATO IP4 and the Global Combat Air Programme (GCAP). GCAP, a new Japan-Italy-U.K. partnership for the development of a sixth-generation fighter jet, has been described as a "new alliance" since the multilayered cooperation between the three governments, militaries, and industries will inevitably strengthen security ties among the three nations. Japan's extensive and asymmetric dependence on U.S. defense collaboration and procurement has long been a source of frustration for Japanese officials and defense companies. According to a defense expert interviewed in July 2024, Tokyo maintains a "painful memory" of its co-development with the U.S. on the F-2 fighter program in the 1980s, which continues to shape Japanese perceptions. U.S. restrictions on the sharing of confidential technical information, coupled with the inability to freely modify procured systems without U.S. approval, have complicated both co-development programs like the F-2 and procurement of F-35s. An expert on Japan's defense industrial policy, also interviewed in July 2024, observed that the U.S. Foreign Military Sales system remains fundamentally "asymmetrical" since "the Japanese government cannot acquire necessary or valuable technological information." This lack of technological freedom creates persistent challenges for Japan's defense autonomy. In reaction to these concerns, Japan is diversifying defense industrial collaboration. Beyond GCAP, Japan is partnering with the U.K. on Joint New Air-to-Air Missiles (JNAAM) and a universal radio frequency sensor technology (JAGUAR), while collaborating with France on mine countermeasures, and trilaterally with France and Germany on railgun technologies. Reflecting this trend, the Financial Times reported on a notable increase in the presence of European defense companies at Japan's 2025 Defense and Security Equipment International (DSEI) expo. Moreover, in November 2024, Japan and the EU issued the "Japan-EU Security and Defence Partnership," their first-ever document outlining concrete cooperation initiatives in maritime security, space, cybersecurity, and hybrid threats. These efforts have gained urgency with Trump's return to the White House, as his administration's transactional approach to alliances raises new uncertainties for all allies. While these initiatives do not indicate a pivot away from the United States, they mark the growing significance of European partners for Japan. According to the Financial Times, Tokyo canceled the annual "two-plus-two" security dialogue scheduled in Washington after the U.S. suddenly asked its ally to boost defense spending to 3.5 percent -- higher than its previous request of 3 percent. Whether the cancellation was due to Washington's latest demand or a simple scheduling conflict, there is no denying that the two allies will need to face some difficult conversations in the coming months. Lack of technological freedom and overreliance on the U.S. for defense technology risk making Japan a captive of its own alliance, as the U.S. president has shown little hesitation in demanding higher purchases of American weapon systems, including offering the new F-47 to Japan as a bargaining chip in tariff negotiations. As Washington increasingly treats arms sales and security guarantees as transactional tools for managing trade imbalances, Japan, like Europe, faces the challenge of balancing U.S. demands while seeking diversification for its security partnerships. Ishiba's absence from this year's NATO summit, while shielding Japan from potentially difficult discussions with Washington in the short term, is therefore a missed opportunity for advancing ties with NATO partners at a critical moment. One of the objectives of the newly established Mission of Japan to NATO is to enhance European understanding of Japan and the Indo-Pacific. Ishiba's decision not to attend following the cancellations by other IP4 leaders may show a lack of leadership in the region, but it also risks sending the signal to Europeans that the Indo-Pacific is, after all, not as important as when former Prime Minister Fumio Kishida used to repeat "Ukraine today may be East Asia tomorrow." Ishiba, who replaced Kishida in October 2024, has yet to visit Europe, despite the fact that relations with European countries have taken on increasing importance in recent years. His personal engagement with European leaders would have signaled Japan's commitment to deepening these strategic partnerships -- a gesture increasingly valuable as both Japan and its European partners navigate the uncertainties of managing their respective alliances in the coming years.

JCP vows fairer taxes, stronger social safety net and a commitment to peaceful diplomacy
Sunday's Upper House vote will be an election of historic significance for the future of Japan. The Japanese Communist Party will do everything in its power to help voters drive the Liberal Democratic Party and Komeito into a minority in the House of Councilors and bring an end to LDP rule. Like millions of voters, we call out the LDP-Komeito conservative coalition and call for equally harsh judgment of their complementary forces — Nippon Ishin no Kai and the Democratic Party for the People. As the oldest political party in Japan, we will resolutely fight against xenophobia and extreme right-wing trends. The LDP's politics are now in a terminal and critical state with the party unable to respond to domestic and international issues or the wishes of the people. Many people are suffering from rising prices, yet the LDP is completely ill-equipped. Its members offer only short-term repairs — not long-term solutions — to the surge in rice prices and rice shortages. Pensions, medical care, nursing care and social security — all are in a growing state of crisis and the ruling coalition is heading down a path that will only make things worse. Real wages have been negative for three consecutive years, yet no one is taking political responsibility to raise wages and provide relief for Japan's workers. At the root of all this is the distortion of politics that prioritizes the interests of the business world and large corporations. On the foreign-policy front, Japan's challenges are just as great. How should we deal with President Donald Trump's America? Should we continue down the path of military expansion as Washington tells us to? How should we respond to the Trump administration's unjust tariffs? Or being forced to construct a new U.S. military base in Okinawa and turn our backs on the Treaty on the Prohibition of Nuclear Weapons? Can we continue to be at the mercy of America? The JCP believes that if we want to realize the earnest wishes of the people, we need to reform the LDP's 'business-centered' politics and stop putting ourselves at the mercy of the person in the White House. The expansion of the JCP, which cuts into these two distortions, is a sure way to improve Japanese politics and our nation's standing in the world. Please help our party make a breakthrough in this historic election by voting for the JCP candidate in your area. Our basic policies have remained consistent throughout the years and always put the interests of the average Japanese worker first. As a party that has consistently advocated for the abolition of the consumption tax, the JCP will do its utmost to urgently reduce the consumption tax to 5% with the aim of abolishing it. The big problem is how to secure the funds for this. We propose ending the tax-cut handouts to large corporations, which Prime Minister Shigeru Ishiba says he regrets and has admitted are 'ineffective.' We will fund the abolishment of the consumption tax by correcting the tax cuts and preferential treatment for large corporations and the wealthy, including reviewing the preferential tax system for the wealthy commonly referred to as the '¥100-million wall' because tax burdens relative to income drop for earners of more than ¥100 million. In addition, we will promptly raise the minimum wage to ¥1,500 per hour, aiming for ¥1,700. To achieve this, we will impose a temporary tax on a portion of the internal reserves of large companies, which have accumulated to over ¥500 trillion, and use the resulting financial resources to support wage increases for small and medium-sized enterprises. In conjunction with wage increases, we will reduce working hours and increase 'free time,' while improving the treatment of nonregular workers and eliminating unjust termination of employment. On the agricultural front, we will change the erroneous policy of forcing rice farmers to reduce their acreage and production, and promote increased rice production, ensuring a comfortable supply and demand, as well as price guarantees and income compensation for farmers. The politics of pitting the elderly against the working generation and cutting social security have increased the hardships of all generations, dampened consumption, stirred up anxiety about the future and contributed greatly to economic stagnation. We will change this and work to improve social security. In terms of political reform, we will ban corporate and organizational donations and eliminate money-based corruption. For younger people, we will aim to make tuition free up to university. We will increase public education spending to the OECD minimum level and improve poor educational conditions. We will also correct excessive competition and management in education, while creating a rent-reduction and rent-subsidy system and promoting the construction and supply of public housing. On the foreign-policy front, we will reject the Trump administration's demand for a massive military expansion, stop the creation of a warring nation based on the Japan-U.S. alliance and devote our efforts to diplomacy to build peace in East Asia. To address the climate crisis, we will aim to reduce greenhouse gas emissions by 75%-80% by 2035, phase out nuclear and coal-fired power plants and promote a shift to renewable energy and energy conservation. Last but not least, we will promote gender equality, including optional separate surnames for married couples, the early realization of same-sex marriage and the correction of the wage gap between men and women. We will also continue to work to eradicate discrimination and hate speech against foreign nationals, protect the rights of foreign workers and promote the revision of immigration laws in accordance with international human-rights law. Tomoko Tamura is the chairwoman of the Japanese Communist Party. In the lead-up to the July 20 Upper House election, The Japan Times reached out to the nation's major political parties requesting an op-ed for our Opinion pages on why this election is so crucial and why their party deserves the citizens' vote. We are publishing all those who responded.

Japan populist party faces complaint over alleged false online post
YOKOHAMA (Kyodo) -- A local chapter of the Japanese Communist Party said Wednesday it has filed a criminal complaint against the minor populist Sanseito party over an allegedly false social media post ahead of the July 20 House of Councillors election. The post, made on July 7 by the 48-year-old Sanseito candidate in Kanagawa Prefecture, wrote, "Many of my colleagues were murdered by Communist Party members, and the methods were brutal. I still live in fear." He is a former Tokyo Metropolitan Police officer. The JCP said that it delivered a written protest on July 8, demanding an apology and retraction, but received no response, prompting it to file the complaint with prefectural police on Tuesday for defamation and dissemination of false information. The branch argued that leaving the post unchallenged would undermine the fairness of the election, with its chief saying, "There is no truth to the claim that many police officers were killed by Communist Party members." "While policy debate should be open and free, lies and hate speech must not be tolerated," the chief added. In response to media inquiries, the Sanseito candidate defended the post by citing two incidents from the 1950s, including one in which a police officer was fatally shot. "It is a fact that the suspect in the case was a Communist Party member. There's nothing wrong with saying so," he said. Under Japanese laws, knowingly making false statements about others in connection with an election can constitute a criminal offense. The case has drawn attention amid heightened scrutiny of misinformation and inflammatory rhetoric during campaigns. In the run-up to the upper house election, Sanseito has gained traction by advocating stricter controls on foreign residents under its "Japanese First" banner, ranking second in popularity in some recent media polls.
