Miyuki Ishikawa (石川 ミユキ, Ishikawa Miyuki, 5 February 1897 – 30 May 1987) was a Japanese midwife, real estate agent and serial killer. During the US occupation of Japan, she and several accomplices are believed to have murdered dozens of infants, a crime spree known as the Kotobuki San'in incident.

Early life[edit]

Miyuki Ishikawa (née Omaru or Komaru (小丸)[4][5]) was born in the village of Honjō in Miyazaki Prefecture. In 1914 she moved to Tokyo, where she graduated from the Tokyo Imperial University as a midwife on 30 September 1919.[4] That same year she married Takeshi Ishikawa, three years her senior, originally from Ibaraki Prefecture.[6] Takeshi, a former Kenpeitai sergeant and police officer, helped his wife's midwifery work without a regular job.[7] Miyuki had had a hysterectomy so the marriage produced no biological children, [8] but the couple raised a boy from Takeshi's previous marriage and adopted three other children (two boys and one girl).[9]

Miyuki was an experienced midwife, and managed a maternity home named Kotobuki San'in (寿産院 / 壽產院), holding some important positions of multiple midwives associations.[7] In April 1947 she unsuccessfully ran in the election of Shinjuku Ward's assembly members.[7]


In the late 1940s, during the immediate postwar period, many babies were kept at Kotobuki San'in. Most of them were born out of wedlock, and their real mothers were too impoverished to properly raise their children. Due to a decrease in foster parents, Ishikawa chose to neglect numerous infants, many of whom died as a direct result. Almost all of the other midwives employed by Ishikawa were disgusted by this practice and resigned from their positions.[10]

At the same time Ishikawa also attempted to garner payment for these murders. She and Takeshi solicited large sums of money from the parents, claiming that it would be less than the actual expense of raising their unwanted children. Shirō Nakayama, a doctor, was also complicit in this scheme and aided the couple by falsifying death certificates. The number of infants listed at Kotobuki San'in and burial permits issued to the maternity home each year are charted below;[10][11][note 2]

Burial Permit 0 0 1 24 53 6 84

Arrest and trial[edit]

Two police officers from Waseda police station accidentally found the remains of five of Ishikawa's victims on 12 January 1948. Autopsies performed on these bodies proved that they had not died of natural causes.[note 1] Ishikawa and her husband were arrested on 15 January.[8] There were seven surviving infants at Kotobuki San'in at this point, but two died soon afterwards.[13] Public Health and Welfare Section (PHW) at GHQ/SCAP and Tokyo-Kanagawa Military Government District also dispatched some officers to Kotobuki San'in.[14]

Upon further investigation, the police found the ashes of over forty infants in the house of a mortician, and those of thirty more in a temple.[15] The sheer number of dead bodies recovered and the length of time over which the murders took place made it difficult for the authorities to determine the exact number of victims. In court, prosecutors asserted that the couple had murdered at least twenty-seven infants between April 1946 and January 1948.[10]

On 11 October 1948, the Tokyo District Court found the couple guilty of five murders (including the two infants that were found alive but who passed quickly afterwards) by omission, and sentenced Ishikawa and her husband to eight and four years' imprisonment respectively.[16] Both the couple and the prosecutors appealed the sentences by 16 October.[17] On 28 April 1952, the Tokyo High Court sentenced Ishikawa to four years in prison and Takeshi to two years, granting pardons by effectuation of the Treaty of San Francisco.[13] The Supreme Court of Japan rejected the second appeal on 15 September 1953.[18]

Social impact[edit]

Because the victims were deserted children, Ishikawa insisted that parents were responsible for their deaths. Some people, including Musei Tokugawa,[19] supported the assertion. Yuriko Miyamoto criticized them, however, saying it was an example of discrimination against deserted children.[20] Moreover, it was revealed that each of the other eleven maternity homes in Tokyo had also committed crimes similar to Kotobuki San'in case by the end of 1948.[21]

Several intellectuals, such as doctor Takashi Hayashi (林髞) (Takatarō Kigi (木々高太郎)) and politician Tamayo Miyagi, advocated that Japanese government should begin to consider the legalisation of abortion in Japan in order to prevent recurrence of such incidents.[7] On 13 July 1948, the Eugenic Protection Law (now the Mother's Body Protection Law) was established. On 24 June 1949, abortion for economic reasons was legalised under the Eugenic Protection Law in Japan.[22]


In 1969 Ishikawa was interviewed by Shūkan Shinchō magazine, claiming innocence in the murders. Following the end of her sentence, she began to work selling soap, cream and fish. At the time of the interview, Takeshi was already dead and Ishikawa was operating a real estate office in Tokyo. Her former lawyer imagined that she had earned about 100 million yen.[13]

Ishikawa's name and address (same as Kotobuki San'in) were listed in telephone directories between 1954 and 1987.[23][24] As well, her name was on the industry's lists as a representative of a real-estate agent, whose address was also same as Kotobuki San'in, until the end of 1986.[25][26]
