Saturday marks one year since Japanese Prime Minister Sanae Takaichi made her erroneous and dangerous remarks provocatively suggesting that a contingency in the Taiwan Strait could constitute a survival-threatening situation for Japan.
The most revealing feature of the ensuing diplomatic crisis is not simply that Takaichi has refused to retract her remarks and apologize, but that, while repeatedly professing her so-called "willingness" to engage China in dialogue, her government has continued to dismantle the political and institutional restraints that have defined Japan's postwar security policy.
The latest warning sign is Tokyo reportedly considering allowing nuclear weapons to enter Japanese territory under certain "emergency circumstances". By invoking a 2010 parliamentary statement by a former foreign minister as a possible justification for an exception to the principle of not permitting the introduction of nuclear weapons, the Takaichi government would effectively hollow out one of Japan's Three Non-Nuclear Principles.
This is part of a broader attempt to redefine Japan's postwar identity. Her government is preparing to revise three key security documents by the end of this year, with a view to expanding the country's offensive capabilities, loosening restrictions on arms exports and reconsidering the wording of the non-nuclear principles. The deployment of long-range missiles capable of striking targets far beyond Japan's territory has already given this transformation a concrete military dimension.
The historical dimension makes the situation even more troubling. This year marks the 80th anniversary of the opening of the Tokyo Trials, yet Takaichi's political approach has offered little indication of a serious reckoning with Japan's wartime aggression and crimes. Her Aug 15 memorial made no reference to the suffering inflicted on neighboring countries by Japan's imperial militarism. Her offerings to the notorious Yasukuni Shrine, which honors 14 convicted Japanese Class-A war criminals from World War II, have further undermined confidence that her government is willing to face squarely the past.
At the United Nations, she has called for the deletion of the so-called "enemy-state clauses" in the UN Charter — intended to prevent a resurgence of militarism — while promoting Japan as a "peace-loving" country. But the contradiction between such diplomatic language and government's actions are becoming increasingly difficult to disguise. She has already brought forward the target of raising defense spending to 2 percent of GDP, while the 2026 military budget exceeded 9 trillion yen($56.8 billion), and her government is expanding the country's military network, engaging in closer operational coordination with the United States, arms transfers and intelligence cooperation with the Philippines, and deeper military ties with NATO, which is increasingly embedding regional geopolitical competition in its strategy. This approach risks confrontation and conflict in a region which is otherwise making concerted efforts to maintain stability.
There is also a domestic economic contradiction. Japanese businesses have repeatedly sought to restore high-level exchanges with China, recognizing the costs of allowing political tensions to disrupt commercial relations. Bilateral trade has remained resilient, and business delegations have gradually resumed engagement. But the efforts of the Japanese business community cannot substitute for political responsibility.
Japan's security cannot be strengthened by selectively forgetting history, weakening political restraints or treating neighboring countries' legitimate concerns as obstacles to be overcome. Nor can a country claim the moral authority of a victim of nuclear warfare while opening the door to the introduction of nuclear weapons.
The real test of Takaichi's commitment to a stable relationship with China is therefore not how frequently she invokes dialogue, but whether she is prepared to correct her erroneous Taiwan remarks, respect the political foundations of bilateral relations and demonstrate genuine commitment to Japan's postwar pacifist obligations. Without such changes, the language of dialogue will remain at odds with the reality of Japan's increasingly dangerous breaking of the postwar restraint.
This is not simply a matter of inconsistent messaging; it is a structural feature of her government's politics.
