Ryodai Yamazaki - Principal Researcher - Representative Director - Head of Organization Management Division Specializing in international economics and development economics, Yamazaki has deep insights into the economic growth and social inclusion of emerging countries, and the economic aspects of multicultural societies. He has been interested in the international community since high school, and through his research on economic integration and cultural diversity in Southeast Asia, he has focused on the possibility of economic synergy brought about by multicultural coexistence. He is currently writing a thesis on the theme of "Economic Synergy in a Multicultural Coexistence Society," and the results of his research are expected to have an impact not only on the academic world but also on the policy-making field. In 2024, he co-founded the NPO organization "Brave Hearts," which aims to realize a multicultural coexistence society, and became its representative director. Brave Hearts' activities are diverse, including analyzing multicultural coexistence societies from an economics perspective and making innovative policy proposals regarding the balance between the economic contribution and social integration of foreign workers. The Multicultural Coexistence Policy Research Lab is conducting research on "Harmonizing national economic strategies and multicultural coexistence policies in the age of globalization," and will organically link Brave Hearts' practical activities with academic research to present a concrete path toward realizing a multicultural society. Representative Yamazaki's research and activities show that multicultural coexistence is not merely an ideal, but can be a realistic strategy for achieving both economic growth and social development. In today's society where globalization is accelerating, his presence is attracting more and more attention as someone who opens up new horizons for multicultural coexistence policies in Japan.
