Dr. Masahide Kanayama — a highly respected New York endometriosis surgeon — is facing extradition to Japan over an allegation related to oil found on a Buddhist temple. We are asking authorities to halt this extradition until his case is fully and fairly reviewed with complete transparency. No one should be sent across the world to face charges without absolute confidence that they will receive fair treatment and an unbiased process.

Dr. Kanayama is not just any doctor. He is one of the few surgeons in the world with the skill to properly remove deep endometriosis and adenomyosis, conditions that cause severe pain and infertility for millions of women. Not only that, Dr. Kanayama developed deep haptic excision, a safe and effective technique that fully and precisely removes endometriosis. His work has given countless women the ability to start families, return to their lives, and finally live without constant pain. Losing him would be a devastating blow to patients who depend on his rare expertise — many of whom have traveled from across the globe for hope they can’t find anywhere else.

There are serious concerns about whether he will receive a fully impartial and just legal process abroad. International human-rights standards require that every person have the right to a fair hearing, and this principle must be upheld before any extradition takes place. Dr. Kanayama deserves the chance to present his side and have the evidence reviewed without pressure, bias, or assumptions.

Extradition is permanent. Once it happens, there is no undoing it — and no second chance to protect his rights or his patients’ well-being. His removal would not only affect him; it would deeply impact the women whose lives he saves and improves every single day.

By signing this petition, you are standing up for justice, fairness, and compassion. You are standing with the many women whose futures depend on Dr. Kanayama’s unmatched medical skill. And you are calling for a careful, humane, and responsible review before any final decision is made.

Please join us in protecting both due process and the vital medical work that changes lives.
