Egg donation is not prohibited in Japan, but the rules are not well established. With the exception of some cases such as infertility due to illness, it is mainly prohibited overseas.
At least 340 people have received egg donation in Japan since 2020. A bipartisan coalition of parliamentarians is working on drafting a bill regarding assisted reproductive technology, including egg donation, with the aim of submitting it to the current Diet session. It is difficult for those who have received the donation to tell the people around them. It has become clear that reality precedes any discussion of the points.
