Sejima was appointed to the Board of the United States-Japan Foundation, recognizing her leadership and role in cultural exchange.
On March 30, 2023, the United States-Japan Foundation announced the appointment of Kazuyo Sejima to its Board of Directors, recognizing her international stature as an architect and her contributions to strengthening cultural ties between the United States and Japan.
The Foundation, established to promote mutual understanding and cooperation between the two nations, selects board members from among leaders in business, academia, arts, and public policy. Sejima's appointment reflected both her architectural legacy—including internationally significant projects in the United States such as the New Museum in New York and the Grace Farms project in Connecticut—and her broader cultural influence as a globally recognized Japanese figure.
Her involvement with the Foundation extended her impact beyond individual building projects into the realm of cultural diplomacy, using her platform to foster exchange programs, joint initiatives, and greater mutual appreciation between American and Japanese architectural and artistic communities.
This appointment underscored the breadth of Sejima's influence, illustrating how her career had evolved from a purely design-focused practice into a broader role as a cultural ambassador and institutional leader.
