Photo: Since its completion soon after World War II, the I-House building, while undergoing periodic reconstruction and revitalization, has continued to support the I-House mission. Constructed under the collaboration of three prominent Japanese architects—Maekawa Kunio, Sakakura Junzō, and Yoshimura Junzō— it was awarded the Architectural Institute of Japan Prize and in 2006 was registered as a tangible cultural property by the Agency for Cultural Affairs of Japan.
