Chinese navy ships passed through the waters around Japan’s Nansei Islands 68 times in 2024, according to Japanese defense officials. This number is more than three times the incidents recorded in 2021, raising concerns about regional security. Japan has responded by increasing its military presence and strengthening alliances with the United States.
“China’s naval movements are a clear signal of its growing influence,” said Japanese Defense Minister Minoru Kihara. “We must remain vigilant and prepared.” The Japanese government has called the increased activity a serious threat to national security.
The Nansei Islands stretch southwest from Japan’s mainland toward Taiwan. Their location makes them a key area for military operations in the Indo-Pacific. China’s frequent presence there has raised fears of future conflicts in the region.
China claims its naval operations are routine and comply with international law. However, Japan and its allies see the increase as a strategic move to expand China’s control over vital sea routes. Beijing has also sent more aircraft near Japanese airspace, forcing Japan’s air force to respond.
“China’s actions threaten stability in the region,” said a senior U.S. military official. “Japan and its allies must coordinate a strong response.” The United States has pledged to support Japan’s defense efforts through joint military exercises and intelligence sharing.
Japan has been modernizing its military to counter growing threats from China and North Korea. Recent defense spending increases have focused on missile defense systems, naval expansion, and cyber warfare capabilities. Tokyo has also worked closely with Washington to improve security cooperation.
The rise in Chinese naval activity comes as tensions remain high over Taiwan. Beijing has not ruled out the use of force to reunify with Taiwan, a scenario that would directly impact Japan. The Nansei Islands could play a crucial role in any potential conflict.
Japan has warned China against aggressive military actions in the region. Tokyo has also strengthened ties with regional allies, including Australia and the Philippines. These partnerships aim to counterbalance China’s growing military presence in the Indo-Pacific.
China’s navy is now the largest in the world by total ship count. Its expanding capabilities include advanced aircraft carriers, submarines, and missile systems. Japan and its allies view these developments as a direct challenge to the current balance of power in Asia.
The Japanese government is closely monitoring future naval movements near its territory. Officials have stressed that any further escalation could lead to increased defense measures. The region remains on high alert as tensions between China and its neighbors continue to rise.
