Japan adopts annual defence white paper prioritising drones and AI, citing China, Russia and North Korea
How left and right are reading this
- Both 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.
- They split on
- Whether the story is about a democracy owing itself an open argument before it buys unmanned weapons and expands arms exports, or about whether anyone is left to build the deterrent East Asia now requires.
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.
