Japan PM Warns Taiwan Crisis Could Justify Armed Response

Japanese Prime Minister Sanae Takaichi stated on October 24, 2023, that a military action by China against Taiwan could be considered a “survival-threatening situation” for Japan. This assessment would potentially enable Japan to mobilize its armed forces in response. Takaichi’s remarks were made during a parliamentary session in response to inquiries regarding whether a “Taiwan contingency,” specifically involving a Chinese naval blockade, meets the criteria for such a situation under Japan’s security laws.

Takaichi emphasized the seriousness of the situation surrounding Taiwan, indicating that if Chinese warships and other military actions were involved, it could justify Japan exercising “collective self-defense.” This principle allows Japan to respond even if it is not directly attacked, particularly in defense of an ally such as the United States. According to a report by Asahi Shimbun, Takaichi stated, “If warships are used and other armed actions are involved, I believe this could constitute a survival-threatening situation.”

While Takaichi acknowledged the gravity of the Taiwan situation, she also clarified that not all disruptions in the Taiwan Strait would meet the threshold for a military response. For instance, she noted that civilian vessels attempting to block passage would not qualify as a survival threat.

The Prime Minister’s comments reflect a broader sentiment within Japan’s political landscape. Former Prime Minister Taro Aso, a member of Takaichi’s Liberal Democratic Party, has frequently articulated similar views, asserting that a conflict across the Taiwan Strait would be perceived as a survival threat to Japan.

In a notable address in 2021, former Prime Minister Shinzo Abe cautioned against any potential invasion of Taiwan by Beijing, stating, “A Taiwan contingency is a contingency for Japan.” He further reinforced the idea that the situation in Taiwan also impacts the Japan-U.S. alliance and urged Chinese leadership not to misinterpret Japan’s stance.

Takaichi, who assumed office as Japan’s 104th Prime Minister last month, is recognized for her supportive approach towards Taiwan and aligns with the foreign policy direction established by the late Abe. Her recent statements underscore Japan’s ongoing concerns regarding regional security and the implications of Chinese military actions in the area.

As tensions continue to rise in the Asia-Pacific region, Japan’s government is increasingly preparing for various scenarios that could emerge from the ongoing situation in Taiwan, reflecting a shift in Japan’s defense posture in response to perceived threats from China.
