Abstract: Japan’s amended Act on the Promotion of Ensuring National Security through Integrated Implementation of Economic Measures, known as the Economic Security Promotion Act (ESPA), cleared the House of Councillors in June 2026.

The amendment does five things: it widens the range of support available for securing a stable supply of specified critical materials, and so strengthens supply chains; it brings an additional industry within the critical infrastructure services regime and improves how that regime is administered; it expands the set of funds eligible to support the development of advanced technology; it extends support to overseas projects that matter for economic security; and it establishes a dedicated research organization and a public-private council for economic security.

What stands out in this amendment is that the territory covered by Japan’s economic security legislation has expanded from the tangible to the intangible and from domestic activities to overseas activities. This study examines what is new in the amended ESPA and sets out the implications for Korea’s economic security policy.
