An absence of any statutory law in Japan regarding donor conception creates uncertainty about the status of donors in relation to the child(ren) born as a result. Laws that provide for certainty regarding the status of the donor are called for, as are laws that address donor anonymity. It would be pragmatic to introduce a prospective system that requires open donation, allowing information to be recorded and released to donor-conceived people upon request. For past donations, a voluntary register should be established, which would allow those people who are seeking information to register this.
