The Birth of SamuraiDonor
When I learned that a dear friend couple from the US, residing in Japan, was unable to have children due to male infertility, I was deeply moved.
They asked me if I would consider being a sperm donor, a request that initially took me by surprise. After careful consideration and research, I realized the significant need for accessible sperm donation services, especially for foreigners living in Japan.
Inspired by my friends’ courage and determination, I founded SamuraiDonor to support those facing similar challenges.
