Abstract
This is a study aimed to ask what "parent and child" and "family" mean from a legal point of view, and to consider the rights of a "child" born from assisted reproductive technology involving a third party. Specific issues of "the right to know one's origin" in Japan and all issues that might arise from the perspectives of the parent–child relationship and family law have been examined. "The right to know one's origin" is defined as the right of the child to know "how he/she was conceived and who the parents are." There are currently no laws regarding "the right to know one's origin" in Japan. Based on the above, in the final chapter, it is shown that "the right to know one's origin" of children born from assisted reproductive technology is seen as being a "benefit to the child," and considered necessary for the child's protection. As a research method, we conduct a literature survey and analyze the "right to know one's origin" of children born from assisted reproductive technology involving a third party, and the "right not to know one's origin", which is a related right. In conclusion, in order to the importance of the "interests of the child," clarify the relationship between the "right to know one's origin" and the "right not to know one's origin" and the need for public management of information are stated.
