Japan’s Defense Chief Says AI Guidelines Land Late November

Three pillars

Koizumi named three core principles. The first is that humans make the decisions when AI is used, and humans answer for the results.

The second is turning data into strength for the country's defense. The third is balancing the fast spread of AI across the ministry with stronger safety measures.

"We will utilize AI and data to strengthen our country's defense capabilities," Koizumi said. "We want to show a new direction."

Part of a wider technology push

The announcement follows Japan's 2026 Defense White Paper, released on August 4. The paper points to deeper use of commercial technology, AI, drones, space and electromagnetic capabilities, and closer ties with start-ups and the private sector.

It describes the regional security environment as the most severe since World War II and calls China an "unprecedented strategic challenge." It also names North Korea and Russia as threats, and prepares the ground for revised core security strategies by year's end.

Koizumi has also been working on cooperation with Washington on cyber defense. Japan's defense minister and his US counterpart agreed in late October to strengthen joint efforts to prevent cyberattacks.

The ministry has not yet said how the guidelines will be enforced, or which specific military uses of AI they will cover. They are due at the end of November.
