Japan-China Tensions Rise: Defense White Paper Features Heartwarming Manga Cover as Shinjiro Koizumi Expresses 'Unprecedented Sense of Crisis'

Japanese Defense Minister Shinjiro Koizumi released the annual Defense White Paper on Tuesday (August 4), stating that Japan has a 'stronger sense of crisis than ever before' to enhance its defense capabilities, citing frequent military activities by China, North Korea, and Russia as one of the reasons.

Japan's Cabinet approved the 2026 edition of the 'Defense White Paper' on the same day (August 4), noting that China is enhancing its military capabilities and expanding its operational reach around Japan from the so-called 'first island chain' to the 'second island chain.' Examples cited include the deployment of Chinese aircraft carriers and two incidents in June and July 2025 where Chinese and Japanese military aircraft came abnormally close.

According to reports, Japanese fighter jets conducted 595 emergency scrambles over the 12 months ending in March, with 366 scrambles in response to Chinese military aircraft and 214 in response to Russian military aircraft. The previous year's total scrambles amounted to 704.

Japan has already increased defense spending, deployed missiles to remote islands, and begun building counterstrike capabilities. Meanwhile, Tokyo significantly relaxed its self-imposed restrictions on weapons exports in April. At the same time, the White Paper warns of weaknesses in Japan's domestic defense industry, suggesting these could jeopardize future weapons procurement and innovation.

The 2026 edition of the 'Defense White Paper' includes several reader-friendly features, such as a manga-style cover and links to video clips in Japanese, English, and Chinese.

Japan to Strengthen Combat Drone Development

The White Paper introduces a new section titled 'New Forms of Warfare,' emphasizing that Japan should strengthen the application of emerging technologies in defense. Citing the war in Ukraine and recent Middle East conflicts, the Japanese government stresses the need to adapt to new combat methods such as drones and artificial intelligence (AI) used in Ukraine and the Middle East, and to strengthen its domestic defense industry.

Japan's Acquisition, Technology & Logistics Agency (ATLA) recently selected four drone manufacturers from dozens of applicant companies to participate in a rapid development program. For example, Toshiba announced last week that it plans to jointly develop combat drones with startup Pro Drone. These companies will undergo testing in early August, after which final selections will be made. Experts have already pointed out that, given that Japan's civilian drone market is currently dominated by Chinese imports, developing fully domestically produced drones will be challenging.

Defense Minister Shinjiro Koizumi also mentioned on Tuesday the 'unshakable' alliance with the United States and increasingly close security cooperation with the Philippines, Australia, and South Korea. China has closely watched the release of Japan's annual 'Defense White Paper' and its announcement of military buildup, accusing Japan of reviving 'militarism.' Chen Xi, spokesperson for China's Ministry of National Defense, expressed strong dissatisfaction and firm opposition during a press conference on August 4, stating that Japan's new 'Defense White Paper' 'exaggerates the so-called 'China threat' and regional security crisis,' calling it 'thieves crying 'stop thief'' and merely an excuse to loosen its own military constraints.

Sino-Japanese relations deteriorated after Japanese Prime Minister Sanae Takagi made remarks shortly after taking office last year about 'Taiwan contingencies' and hinted at possible military intervention by Japan in a Taiwan Strait conflict. The new 'Defense White Paper' explicitly identifies China as Japan's greatest strategic challenge, which could further worsen bilateral relations.
