Japan weighs nuclear-powered submarine acquisition in defense strategy update

Japan is considering adding language on 'investigation' and 'research' into nuclear-powered submarine acquisition in its upcoming National Security Strategy revision, due by year-end. This marks a potential shift in Japan's post-war defense posture, though it remains at an exploratory stage with no formal commitment. The move would have significant implications for regional naval balance and alliance dynamics, particularly vis-à-vis China.

This potential shift from a conventional submarine-only posture is currently at an exploratory stage, with no formal decision or timeline established. The feasibility and implications for regional balance and alliances remain uncertain.
