　　About seven years after the Hiroshima atomic bomb was dropped and exploded on August 6, 1945, a mother died of leukemia resulting from the atomic bombing at a mother-child treatment center in Motomachi, Hiroshima. The mother died of A-bomb disease, and the remaining orphaned children, boys and girls, laid incense at the memorial service. The boys were about two years old when their mother was exposed to the bomb, and they had no knowledge or memory of the Hiroshima atomic bomb. The damage caused by the atomic bomb was still continuing after the war.

　The Maternal and Child Dormitories are child welfare facilities that provide comprehensive support for women in single-mother households and other families raising children under the age of 18, including living, housing, childcare, and employment, so that they can live safely with their children and become self-reliant. The requirements for admission are women without a spouse or women in similar circumstances, mothers and children who have various problems in their lives and need support in raising their children. Under the Child Welfare Law, the Child Welfare Center is an institution for the purpose of admitting women without a spouse or women in equivalent circumstances and children under their care, protecting them, supporting their daily lives to promote their independence, and providing counseling and other assistance to those who have left the institution. 1998 In 1998, the name was changed from "Maternal and Child Dormitories" to "Maternal and Child Living Support Facilities" in accordance with the revision of Article 38 of the Child Welfare Law.

　In 1938, the Ministry of Health and Welfare was established and the Maternal and Child Protection Law was enacted. In 1949, the Diet passed a resolution to increase the number of nursing homes, mother-child dormitories, and day-care centers, and in 1947, there were 212 mother-child dormitories, and by 2023, there will be 215 mother-child living support facilities with a capacity of 4,000 children. In 2023, there were 215 mother and child living support facilities with a capacity of 4,441 families, and the current number of families was 3,135, showing a downward trend. At the end of the war, the overwhelming majority of families were bereaved mothers and children who had lost their homes due to the war or the death of their husbands in the war. The mother-child dormitories provided postwar measures and support for mothers and children in dire need of "a roof over their heads, a place to sleep, and a place to live," who had lost their husbands, homes, and families due to the war. In the postwar period, the number of "bereaved mothers and children" increased from "bereaved mothers and children" to "living mothers and children" due to divorce and other reasons, and the use of complex and diverse living issues increased from housing issues.
