Building Japan’s Impact Economy Case Series

Chapter 4: SIIF as Catalyst, Convenor, Collaborator

Introduction The Japan Social Innovation and Investment Foundation (SIIF) is a driving force in Japan’s impact economy, serving as a catalyst, convenor, and collaborator to create lasting social change by connecting capital with purpose. Since its founding in 2017 as a spin-off from the Nippon Foundation, SIIF has piloted innovative financing models, built relationships to grow Japan’s impact investing market, and advocated for best practices in the field. Over the years, SIIF has shaped the field through initiatives like shaping Japan’s first Social Impact Bonds, utilizing Dormant Accounts for social good, and the development of Japan’s Impact Measurement and Management (IMM) Framework. It helped establish GSG Impact JAPAN, convening leaders from finance, business, and government to align their efforts for greater impact. These milestones (as seen in Figure A) reflect SIIF’s commitment to not just funding innovation but also building the infrastructure necessary for a thriving impact economy.

“SIIF is a small organization. We must use our resources wisely. How can we use our assets as a catalyst and a convenor to test new collaborative, community- based models that address systemic challenges? That has been our role since

our inception and continues today.” —Fumi Sugeno, Head of SIIF Global 1
