The passing of His Highness the Aga Khan IV marks the loss of a visionary leader whose profound influence shaped not only the Ismaili community but the architectural and cultural fabric of societies worldwide. At Moriyama Teshima Architects, we are deeply honoured to have collaborated with His Highness on projects such as the Delegation of the Ismaili Imamat in Ottawa, as well as the Aga Khan Museum and the Ismaili Centre in Toronto.

These collaborations embodied more than design—they were guided by His Highness’s belief in architecture’s transformative power to foster pluralism, understanding, and spiritual reflection. Working alongside esteemed architects Fumihiko Maki and Charles Correa, we witnessed firsthand His Highness’s unwavering commitment to creating spaces where tradition and modernity coexist harmoniously and cultural dialogue is nurtured.

His vision challenged us to think beyond physical structures, reminding us that architecture has the potential to be a bridge between communities, a symbol of shared humanity, and a beacon of hope. We extend our deepest condolences to his family, the Ismaili community, and all those inspired by his extraordinary legacy.
