Following a major security policy change in 2022 that included a rapid defense build up, this article reexamines Japan’s 2015 Peace and Security Legislation in the context of the U.N. collective security system and argues that its most significant achievement has been to expand Japan’s power to engage more proactively in the Asian collective security order. In that many focused on how the law expanded constitutional limits to allow collective self-defense, this article argues the deeper significance enabled Japan to respond to a broader range of threats, not just survival-level ones.

Nobuhisa Ishizuka is currently the Executive Director of the Center for Japanese Legal Studies at Columbia Law School. Prior to joining the center, he was a Partner at Skadden, Arps, Slate, Meagher & Flom, where he advised on corporate and financial matters, with a focus on mergers and acquisitions and corporate finance.
