Even though there is no formal diplomatic relationship or direct military cooperation between Taiwan and Japan, as China increasingly threatens Taiwan militarily, Tokyo might pass laws and publish official documents with the aim of developing multilateral joint defense cooperation with Taipei.
This could take the form of a US-Japan-Taiwan military alliance, which would strengthen bilateral cooperation between Taipei and Tokyo, so that the two nations could work closely together to uphold regional peace and security.
In an interview with the Financial Times published on Aug. 2, titled “Japan calls for greater attention to survival of Taiwan,” Japanese Minister of Defense Nobuo Kishi warned about the expanding Chinese military encircling Taiwan and called on the international community to pay greater attention to Taiwan’s survival.
Kishi also said that the military balance in the Taiwan Strait is tipping in favor of China and that the only way that peace will prevail is if the international community robustly demands it.
He also stressed the importance of the relationship with Taiwan, which he noted is only 110km from the westernmost point of Japan.
Tokyo has over the past few months shown a marked increase in interest and concern over the situation in the Taiwan Strait.
Japan has participated in a series of diplomatic conclaves, all of which have resulted in joint statements or joint communiques that have emphasized the importance of maintaining peace and stability in the Strait. This includes the “two-plus-two meeting” in Washington in March, the Japan-US Summit Meeting in April, the EU-Japan Summit in May, the Japan-Australia Foreign and Defense Ministerial Consultation and the G7 Leaders’ Summit in June, as well as the publication of Japan’s annual defense white paper last month.
The continued expansion of Chinese military power has over the past few years not only created an existential threat to Taiwan, but also seriously affected Japan’s security. As early as 2004, a Chinese navy submarine intruded into Japanese sovereign waters, and the following year, five navy surface vessels forcibly entered waters in close proximity to the Chunxiao (春曉) gas field in the East China Sea, unsettling Tokyo.
Since then, Beijing has more frequently displayed shows of strength to Japan, particularly near the disputed Diaoyutai Islands (釣魚台), known as the Senkaku Islands in Japan, which had the effect of further alerting Tokyo to the burgeoning China threat.
As of the end of last month, Chinese-flagged vessels have for 152 consecutive days cruised through the Diaoyutais’ contiguous zone, setting a new record.
Tokyo is acutely aware of Taiwan’s vital strategic importance in East Asia and knows full well that if Taiwan, with its pivotal position in the first island chain, no longer functions as a counter to Chinese military expansion, Beijing will almost inevitably become the military hegemon in the region.
In other words, Japan’s and Taiwan’s national security are closely related: Taiwan’s problem is Japan’s problem.
In addition to the US-Japan military alliance, the international community must squarely face up to the situation and assist Taiwan to bolster its self-defense capabilities to defend against the China threat.
Beijing’s threatening military maneuvers against Taiwan have caused the world to belatedly wake up to the severity of the problem. If the Strait becomes increasingly unstable, it would endanger the security of the entire region.
As Taiwan and Japan’s militaries both use a large amount of US-made systems, the potential for seamless interoperability presents an opening for strategic cooperation.
Japan should use the operational framework of the Japan-US military alliance and Taiwan-US military cooperation, and consider taking a leaf out of Washington’s flexible “one China” policy to emulate something similar to the US’ Taiwan Relations Act and deepen military cooperation with Taiwan.
This would allow the two nations to collectively respond to the China threat and contribute to the international effort to secure a peaceful and stable Strait and Indo-Pacific region.

US President Donald Trump and Chinese President Xi Jinping (習近平) were born under the sign of Gemini. Geminis are known for their intelligence, creativity, adaptability and flexibility. It is unlikely, then, that the trade conflict between the US and China would escalate into a catastrophic collision. It is more probable that both sides would seek a way to de-escalate, paving the way for a Trump-Xi summit that allows the global economy some breathing room. Practically speaking, China and the US have vulnerabilities, and a prolonged trade war would be damaging for both. In the US, the electoral system means that public opinion
In their recent op-ed “Trump Should Rein In Taiwan” in Foreign Policy magazine, Christopher Chivvis and Stephen Wertheim argued that the US should pressure President William Lai (賴清德) to “tone it down” to de-escalate tensions in the Taiwan Strait — as if Taiwan’s words are more of a threat to peace than Beijing’s actions. It is an old argument dressed up in new concern: that Washington must rein in Taipei to avoid war. However, this narrative gets it backward. Taiwan is not the problem; China is. Calls for a so-called “grand bargain” with Beijing — where the US pressures Taiwan into concessions
The term “assassin’s mace” originates from Chinese folklore, describing a concealed weapon used by a weaker hero to defeat a stronger adversary with an unexpected strike. In more general military parlance, the concept refers to an asymmetric capability that targets a critical vulnerability of an adversary. China has found its modern equivalent of the assassin’s mace with its high-altitude electromagnetic pulse (HEMP) weapons, which are nuclear warheads detonated at a high altitude, emitting intense electromagnetic radiation capable of disabling and destroying electronics. An assassin’s mace weapon possesses two essential characteristics: strategic surprise and the ability to neutralize a core dependency.
Chinese President and Chinese Communist Party (CCP) Chairman Xi Jinping (習近平) said in a politburo speech late last month that his party must protect the “bottom line” to prevent systemic threats. The tone of his address was grave, revealing deep anxieties about China’s current state of affairs. Essentially, what he worries most about is systemic threats to China’s normal development as a country. The US-China trade war has turned white hot: China’s export orders have plummeted, Chinese firms and enterprises are shutting up shop, and local debt risks are mounting daily, causing China’s economy to flag externally and hemorrhage internally.
