What is Natsu Camp?
Each summer (“natsu”), we bring together motivated high school students and mentors from diverse cultural and academic backgrounds in a new region of Japan. Together, they explore college-level topics across business, STEM, the liberal arts, and the creative fields — while tackling real-world challenges through research-driven, team-based projects and field experiences in social innovation. This year, six inspiring mentors will guide students in Tokyo through a hands-on, project-based, and truly life-changing summer experience. No prior knowledge required!

Ria Ying Oyama
Stanford University
M.A. in East Asian Studies
Representative Director & Founder
Before founding her own social enterprise, Ria gained valuable experience at the intersection of policy-making and philanthropy upon graduating from Stanford University with a graduate degree in East Asian Studies and a merit-based scholarship. During her time there, she conducted research in international relations at the Shorenstein Asia-Pacific Research Center (APARC). While participating in project implementation with various non-profit organizations, including a UN-affiliated NGO in Africa, she identified inefficiencies in traditional charity models. This inspired her to create Natsu Project, which uses a for-profit model to support non-profit work, ensuring financial independency and meaningful social impact.
