Japanese Prime Minister Sanae Takaichi plans to skip the upcoming Nuclear Non-Proliferation Treaty review conference in New York, opting instead to send a vice foreign minister. This represents a downgrade in diplomatic engagement and signals a shift in Japan's foreign policy from emphasizing moral leadership on nuclear disarmament to prioritizing security and alliance-based deterrence, particularly reliance on the U.S. nuclear umbrella.

Why it matters

The decision reflects a broader shift in Japan's approach to nuclear issues, moving away from its traditional role as a champion of disarmament and toward a more security-focused strategy centered on deterrence. This shift comes as global nuclear disarmament efforts face setbacks, with the lapse of the New START treaty and France's plans to strengthen its nuclear forces.

The details

The upcoming Nuclear Non-Proliferation Treaty review conference in New York has traditionally drawn increasingly senior Japanese representation, with Prime Minister Fumio Kishida becoming the first Japanese leader to attend in 2022. However, the decision to send a lower-level official this year represents a downgrade in diplomatic engagement. A Japanese government official cited the changing international environment, with nuclear deterrence gaining renewed prominence and Japan's role in advancing disarmament becoming more limited.

• The NPT review conference is set to begin on April 27, 2026.
• In 2022, then-Prime Minister Fumio Kishida became the first Japanese leader to attend the conference.
• Japan sent its foreign minister to a preparatory meeting in 2025, marking the first such attendance in nearly two decades.

What’s next

The decision to send a lower-level official to the NPT review conference will be closely watched, as it signals a potential shift in Japan's diplomatic priorities on nuclear issues.
