Rising Concern Over Potential Shift in Japan’s Nuclear Policy Evident in Municipal Resolutions

A wave of resolutions passed by local assemblies underscores growing unease about a potential revision of Japan’s nuclear posture. In total, 82 municipal and prefectural bodies have formally asked the central government to retain the three non‑nuclear principles and to give them legislative force.

Since the Takaichi cabinet’s inauguration last October, five prefectural assemblies, 48 city councils and 29 town and ward assemblies have enacted similar measures, each reaffirming the existing principles without suggesting changes.

Experts compare this level of local advocacy to earlier periods, noting a marked increase in citizen‑driven pressure to safeguard the anti‑nuclear framework that was established by the Diet in 1971.

The three principles bar Japan from possessing, producing, or allowing nuclear weapons on its territory, and they have been a pillar of the nation’s defense doctrine for more than five decades.
