Rising Tensions Over the Senkaku Islands: A Closer Look

In 2024, the Japan Coast Guard reported a record 355 sightings of Chinese coast guard vessels in the contiguous zone surrounding the Senkaku Islands, surpassing the previous year's record of 352 sightings. This trend marks the fourth consecutive year of increased Chinese maritime activity in the area, which is administered by Japan but also claimed by China and Taiwan. The contiguous zone extends 24 miles beyond Japan's 12-mile territorial limit, where nations can exercise limited control. Seishiro Sakamoto, commander of Japan’s 11th Regional Coast Guard, stated, “The situation surrounding the Senkaku Islands is becoming increasingly severe, and the situation remains unpredictable.” He emphasized the need for heightened surveillance and vigilance to protect Japan's territorial waters.

The Senkaku Islands, which include five islets and three reefs located 105 miles east of Taiwan and 254 miles west of Okinawa, are believed to harbor significant oil reserves and other resources. This potential wealth has fueled ongoing disputes between Japan and China since the 1970s. The tensions escalated further when Japanese Prime Minister Sanae Takaichi warned in November 2024 that Japan might resort to military force if China were to attack Taiwan, a self-governing island that Chinese President Xi Jinping has vowed to unify with the mainland, potentially by force.

Japan's Foreign Affairs Ministry has consistently asserted its claim over the Senkaku Islands, while Chinese officials maintain that their activities in the region are “legitimate and lawful.” Lijian Zhao, a former spokesman for China's Foreign Ministry, stated, “The Japanese side has no right to point fingers over these activities.” In 2024, Chinese coast guard vessels entered the territorial waters around the Senkakus 39 times, with incidents of chasing Japanese fishing vessels beyond the territorial limit.

Critics of China's maritime activities argue that these incursions threaten regional stability and violate international norms. The Pentagon has labeled China as an aggressive presence in the East and South China Seas, identifying it as a global “pacing challenge” in its 2022 National Defense Strategy. This perspective is echoed in Japan's 2025 National Security Strategy, which emphasizes the need to compete with China both economically and militarily in the Indo-Pacific region.

While Japan's coast guard has documented the increasing frequency of Chinese vessels in the area, discrepancies exist regarding the exact number of incursions and the nature of these activities. Some reports suggest that Chinese vessels have engaged in more aggressive tactics, such as chasing Japanese fishing boats, while others focus on the broader implications of resource competition.
