Our Donor Recognition
Medal with Dark Blue Ribbon
I-House has been authorized by the Cabinet Office of the Government of Japan as an institution which can recommend the awarding of the Medal with Dark Blue Ribbon. This Medal is given to individuals who have made exceptionally generous financial contributions, i.e. more than JPY5,000,000 as an individual and/or JPY10,000,000 as a corporation, for the good of the public. There will be a screening by the Decoration Bureau of the Cabinet Office following our recommendation. Donation in installments over years is also acceptable, but such an intention should be notified in advance before making the first installment payment.

Donor Nameplate
A commemorative 70th anniversary nameplate was installed in our main building. Names of those donating JPY10,000,000 or more will be displayed on it.



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.
