[Asia Economy Reporter Seoyoung Kwon] A story about a woman in Japan who filed a lawsuit after suffering mental shock upon discovering that the identity of a sperm donor was forged has attracted attention.


On the 12th, local media including Japan's FNN Prime reported that a woman in her 30s living in Tokyo, Ms. A, filed a damages lawsuit worth 332 million yen (approximately 3.4 billion KRW) against sperm donor Mr. B. After having her first child with her husband, Ms. A learned that her husband had a hereditary incurable disease and decided to conceive a child using donated sperm.


Ms. A searched for a donor through social networking services (SNS), receiving direct messages (DMs) from 15 people and conducting in-person interviews with five of them. In Japan, it is common to find sperm donors in this way, and Ms. A set the condition that the donor be a Japanese national without a spouse and with an educational background similar to her husband, who graduated from the University of Tokyo.


Accordingly, Mr. B, a man in his 20s who worked at a major financial institution and graduated from Kyoto University, became the final candidate for sperm donation. Ms. A met Mr. B in person, learning about his family medical history and various other details. Although Mr. B did not reveal his real name, he gained Ms. A’s trust by showing an employee ID from a major company.


Ms. A ultimately selected Mr. B as the sperm donor and, choosing days with high fertility, had multiple relations with him, successfully conceiving a child in June 2019. However, several months later, during the late stages of pregnancy, Ms. A discovered that the sperm donor’s personal information was false. Mr. B was a married man of Chinese nationality who graduated from a national university other than Kyoto University.



Ms. A gave birth in 2020 but suffered from insomnia and mental shock, and due to her physical and mental condition, she entrusted her child to a child welfare facility in Tokyo. She stated, "There should be no other victims like me regarding sperm donation," and demanded damages on grounds including that the man provided false information for sexual pleasure.
