Japan adopts annual defence white paper prioritising drones and AI, citing China, Russia and North Korea
The Facts
- Japan's Cabinet adopted a 598-page annual defence paper on Tuesday; the Defence Ministry report is titled "Defense of Japan 2026."
- The paper reiterates that China is Japan's biggest strategic challenge and also identifies North Korea's missile development and Russia as serious concerns.
- The document includes, for the first time, a chapter on "new ways of warfare" dealing with drones and artificial intelligence, citing their use in Russia's invasion of Ukraine and in Middle East conflicts.
- The government says combat drones will play a key role in coastal defence alongside long-range cruise missiles it has begun deploying, and the ministry says Japan will acquire large numbers of unmanned aerial, surface and underwater vehicles in the current fiscal year.
- Defence Minister Shinjiro Koizumi wrote in the preface that it is "imperative that Japan further reinforce and transform its defense capabilities with a stronger sense of urgency and crisis than ever before."
- The report describes Japan's security environment as the most severe and complex since the end of World War II and says the possibility of a serious situation capable of shaking the postwar order in East Asia cannot be ruled out.
- The paper points to deepening military coordination among China, Russia and North Korea, including joint Chinese-Russian bomber flights and naval exercises and Moscow's support for North Korea's military modernisation; it notes a December bomber patrol that for the first time flew in the direction of Tokyo after passing over Japan's southern islands, and a similar flight path in June.
- The report calls for a stronger domestic defence industrial base, expanded arms exports and deeper ties with security partners, warning that continued withdrawal or downsizing of Japanese defence businesses could affect the stable supply of equipment for the Self-Defense Forces.
- Japan has already been increasing military spending and security cooperation in Asia, deploying missile launchers to outer islands, moving to acquire "counter-strike" capabilities and easing rules on weapons exports.
Context
What is Japan's defence white paper and what period does it cover?
It is an annual Defence Ministry review that outlines Japan's military activity and priorities and analyses military trends in specific countries New Indian Express. This year's roughly 600-page edition reviewed security developments from April 2025 to March 2026, with some issues updated through May and the U.S.-Israeli conflict with Iran through June 毎日新聞,mdz.
What specific Chinese military activities does the report cite?
The paper says Chinese military activities intensified during the review period, citing aircraft carrier operations in the Pacific and Chinese fighter jets approaching Japanese aircraft mdz. Tokyo says it is alarmed by the growing presence of Chinese warships in the Pacific Ocean and the increasing frequency of their activity Mail Online,India Today.
What remains unresolved?
The white paper sets out priorities but does not by itself fund or deliver them: it flags constraints on Japan's defence industry, including firms leaving the sector, and calls for eased arms exports and stronger domestic production Anadolu Ajansı,BFMTV. Prime Minister Sanae Takaichi's government also needs public support for a further build-up of Japan's military capability New Indian Express, and new means of warfare and expanded defence production are expected to form pillars of the next revision of Japan's three key national security documents 朝日新聞デジタル.
Where Left and Right agree, and where they split
- Where Left and Right agree
- Japan's turn to drones, AI and unmanned vehicles this fiscal year is a real strategic shift, not a paper exercise — and the domestic industrial base behind it is genuinely fragile.
- Where Left and Right split
- A democracy owing itself an open argument before it buys unmanned weapons and expands arms exports, or whether anyone is left to build the deterrent East Asia now requires.
How left and right read it
Japan's Cabinet adopted a 598-page defence paper Tuesday with its first chapter on drones and artificial intelligence, and the ministry says large numbers of unmanned air, surface and underwater vehicles will be acquired this fiscal year. Expanded arms exports come with it. So does a larger arms industry. A turn toward unmanned weapons and AI deserves open public argument, not a softened cover image.
“The image showed a smiling family in a gleaming cityscape rather than the troops, weapons and military insignia featured on many previous editions.” — The Independent
A December bomber patrol flew in the direction of Tokyo after passing over Japan's southern islands, and a similar flight path followed in June. That is what strategic self-reliance is for. Japan can call China its biggest challenge and buy unmanned vehicles this fiscal year, but the warning that shrinking defence businesses could disrupt supply to the Self-Defense Forces is the harder problem: who builds the things?
