Eugenics in Japan - After 1945

After 1945

One of the last eugenic measures of the pre-war regime was taken by the Higashikuni government. On 19 August 1945, the Home Ministry ordered local government offices to establish a prostitution service for allied soldiers to preserve the "purity" of the "Japanese race". The official declaration stated that :

Through the sacrifice of thousands of "Okichis" of the Shōwa era, we shall construct a dike to hold back the mad frenzy of the occupation troops and cultivate and preserve the purity of our race long into the future...

Such clubs were soon established by cabinet councillor Yoshio Kodama and Ryoichi Sasakawa.

In post-war Japan, the Socialist Party proposed the Eugenic Protection Law (ja:優生保護法, Yusei Hogo Hō?) which was enacted in 1948 to replace the National Eugenic Law of 1940. The main provisions allowed for the surgical sterilization of women, when the woman, her spouse, or family member within the 4th degree of kinship had a serious genetic disorder, and where pregnancy would endanger the life of the woman. The operation required consent of the woman, her spouse and the approval of the Prefectural Eugenic Protection Council.

The law also allowed for abortion for pregnancies in the cases of rape, leprosy, hereditary-transmitted disease, or if the physician determined that the fetus would not be viable outside of the womb. Again, the consent of the woman and her spouse were necessary. Birth control guidance and implementation was restricted to doctors, nurses and professional midwives accredited by the Prefectural government. The law was also amended in May 1949 to allow abortions for economic reasons at the sole discretion of the doctor, which in effect fully legalized abortion in Japan.

Despite the unambiguous wording of the law, the law was used by local authorities as justification for measures enforcing forced sterilization and abortions upon people with certain genetic disorders, as well as leprosy, as well as an excuse for legalized discrimination against people with physical and mental handicaps.
