Fundraising Campaign of the Century
The International House of Japan (I-House) was established on August 27, 1952. It was a moment when John D. Rockefeller, 3rd and Shigeharu Matsumoto, who believed that an understanding of diverse values and cultures was the key to improving postwar international relations, finally realized their goal of advancing international cooperation.
On November 19 of that year, Prime Minister Shigeru Yoshida inaugurated a fundraising campaign for the construction of I-House. The campaign reached the goal of raising 100 million yen (equivalent to 2.7 billion yen today) at a time when the prime minister’s monthly salary was just 110,000 yen.
Together with matching funds of US$676,000 from the Rockefeller Foundation, the
I-House building was completed in 1955. To mark the occasion, Yoshida donated a work of his own calligraphy, quoting from the Analects of Confucius: “Is it not delightful to have friends come from distant quarters?” This work now hangs in the I-House lobby.
The site of I-House formerly belonged to the Kyōgoku Clan, with ownership subsequently changing to Kaoru Inoue, Prince Kuninomiya, and the Akaboshi and Iwasaki families, before being passed on to I-House. The building was designed jointly by three prominent Japanese architects—Kunio Maekawa, Junzō Sakakura, and Junzō Yoshimura—and was registered as a tangible cultural property by the Agency for Cultural Affairs of Japan. The House Garden, designated a place of scenic beauty, was created for the Iwasaki family by famed landscape designer Jihei Ogawa VII and remains intact to this day. I-House has hosted such renowned global figures as Eleanor D. Roosevelt, Walter Gropius, and Jawaharlal Nehru.
Achieving Our Mission
Contribute to building a free, open, and sustainable future through intellectual dialogue, policy research, and cultural exchange with a diverse world
To realize this mission, I-House aims to become a center of intellectual exchange for not only Japan but also the Asia-Pacific region and to make a greater global impact. We will create and pass on to subsequent generations a “place” where people can co-create a new society and expand our programming. Without your continued support, I-House will be unable to carry out its activities.
