Recent news reports said the US and Japan are planning to station military on Yonaguni Island in response to demands from local residents following China’s military expansion. A closer analysis, however, shows that it is more likely that such a military deployment would be the result of US and Japanese questions about the future strategic direction of Taiwan. In other words, the move is aimed at Taiwan rather than China.
Yonaguni lies almost on the same latitude as Hualien, and when the weather is good, it is possible to see Hualien from the island. Yonaguni residents often go to Hualien for shopping on weekends, and some Yonaguni children study in Hualien. It is the Japanese territory closest to Taiwan. Taiwan shields Yonaguni from China, and it lies quite a distance away from the Philippines, so there can only be two reasons for stationing troops there.
The first reason is that the US and Japan believe there is a very high risk of conflict in the Taiwan Strait, and that after an outbreak of war, it is very likely that Chinese military would enter and leave Taiwan on the east coast, which would be the reason for strengthening the military presence on Yonaguni.
This implies that the US and Japan do not buy into the claim by Taiwan’s government that cross-strait tensions have fallen and that the situation has stabilized, and that they are stationing military east of Hualien to prepare for all eventualities.
The second possibility is that the US and Japan feel the accession of President Ma Ying-jeou’s (馬英九) administration has brought about a fundamental change in the direction of Taiwanese strategy and the two countries are therefore preparing for the possibility that Taiwan would side with China in a hypothetical future conflict between the US and Japan on the one hand, and China on the other.
The fact is that after Ma hinted at the possibility of war with Japan over the Diaoyutai and that he would tolerate calls within the Chinese Nationalist Party (KMT) to side with China against Japan, after the National Security Council’s advocacy that Taiwan abandon its passive sea and air defense, and after the recent refusal to meet with Japan’s representative to Taiwan, Tokyo is questioning the government’s strategy direction, while the US is beginning to worry over the possible Finlandization of Taiwan.
These concerns prohibit the US-Japanese alliance from treating Taiwan as an ally. If Taiwan were to cooperate with their opponent, Hualien would no longer function as a shield from China and Yonaguni would be on the front line of the conflict and it would also be used to monitor Taiwan’s actions.
Regardless of whether the US and Japan station troops on Yonaguni because they are worried about Taiwan or because they want to monitor Taiwan, such action does not coincide with what the Ma administration has said.
Late this year, Japan will announce its defense strategy outline, and next year is the 50th anniversary of the US-Japanese alliance. By that time, the plans of the two allies will become clearer.
However, the fact that the promise to let Taiwan assemble P3-C anti-submarine aircraft fell through tells us that Taipei has become a strategic uncertainty factor.
As a result of the government moving closer to China, distancing itself from the US and opposing Japan, Taiwan has gone from being a friend that cooperates with the US and Japan to a country that the two allies must defend themselves against. The stationing of troops on Yonaguni will be the first step in this change.

The Chinese Communist Party (CCP) has long been expansionist and contemptuous of international law. Under Chinese President Xi Jinping (習近平), the CCP regime has become more despotic, coercive and punitive. As part of its strategy to annex Taiwan, Beijing has sought to erase the island democracy’s international identity by bribing countries to sever diplomatic ties with Taipei. One by one, China has peeled away Taiwan’s remaining diplomatic partners, leaving just 12 countries (mostly small developing states) and the Vatican recognizing Taiwan as a sovereign nation. Taiwan’s formal international space has shrunk dramatically. Yet even as Beijing has scored diplomatic successes, its overreach
In her article in Foreign Affairs, “A Perfect Storm for Taiwan in 2026?,” Yun Sun (孫韻), director of the China program at the Stimson Center in Washington, said that the US has grown indifferent to Taiwan, contending that, since it has long been the fear of US intervention — and the Chinese People’s Liberation Army’s (PLA) inability to prevail against US forces — that has deterred China from using force against Taiwan, this perceived indifference from the US could lead China to conclude that a window of opportunity for a Taiwan invasion has opened this year. Most notably, she observes that
For Taiwan, the ongoing US and Israeli strikes on Iranian targets are a warning signal: When a major power stretches the boundaries of self-defense, smaller states feel the tremors first. Taiwan’s security rests on two pillars: US deterrence and the credibility of international law. The first deters coercion from China. The second legitimizes Taiwan’s place in the international community. One is material. The other is moral. Both are indispensable. Under the UN Charter, force is lawful only in response to an armed attack or with UN Security Council authorization. Even pre-emptive self-defense — long debated — requires a demonstrably imminent
Since being re-elected, US President Donald Trump has consistently taken concrete action to counter China and to safeguard the interests of the US and other democratic nations. The attacks on Iran, the earlier capture of deposed of Venezuelan president Nicolas Maduro and efforts to remove Chinese influence from the Panama Canal all demonstrate that, as tensions with Beijing intensify, Washington has adopted a hardline stance aimed at weakening its power. Iran and Venezuela are important allies and major oil suppliers of China, and the US has effectively decapitated both. The US has continuously strengthened its military presence in the Philippines.
