December 23,1933 marked the birth or the Crown Prince (His Majesty the Emperor Emeritus),long awaited by the Japanese people.
During a birthday celebration held at the Imperial Place on February 23 the following year(1934), the preceding Emperor conveyed to Viscount Minoru Saito, the prime minister, the following Imperial message.
“On the occasion of the birth of the Crown Prince, His Majesty is pleased to grant ￥750,000 as funds for various facilities dedicated to the enlightenment and care of mothers and children in our county. ”
In accordance with the Imperial wish, the four cabinet ministers from the Imperial Household Agency, the Ministry for Home Affairs, the Ministry of Education and the Department of Overseas Affairs deliberated on the matter, resulting in the establishment of the “Imperial Gift Foundation Boshi-Aiiku-Kai, Aiiku Association for Maternal, Child Health and Welfare” on March 13 of the same year(1934).
With Princess Kuninomiya Chikako as president, Count Keigo Kiyoura as chairman, and Teizaburo Sekiya, a member of the House of Peers, as chief director, the association launched activities to promote maternal health and child welfare.

Japan at that time was in a recession, and suffered from deteriorating social conditions.
A ministry of health and welfare and public health centers had yet be established.
Under such insufficient conditions, little attention was given to maternal health and child welfare. This was an insecure period for the Japanese people.
In order to fulfill its founding mission, the Aiiku-kai Association embarked on scientific research relevant to the actual
conditions of people. Authorities in various fields were commissioned to make practical use of the results, leading to the
establishment of the Aiiku Research Committee in May 1934.
Discussions also were held on the possibility of launching comprehensive studies on maternal and child health, welfare and
education by expanding the activities of the Aiiku Research Committee. Upon completion of research facilities in October 1938,
the Aiiku Research Institute was opened in November of the same year. In December of the same year, the Aiiku Medical Office
(Department of pediatrics) was inaugurated as a clinical division. With the addition of an obstetrics devision in Desember 1940,
the Aiiku Medical Office was renamed Aiiku Hospital under the provisions of the 1949 Medical Treatment Law.
Since then, each department takes a close cooperation as a specialized hospital of mother and child, we've been doing a friendly
ongoing medical care to mother and child.
