According to the JADA announcement, two months before the ekiden Nakamura underwent surgical treatment for a gynecological condition. Subsequent injections she received included the prohibited substance. JADA accepted her explanation that these were for post-operative therapeutic purposes but ruled her negligent in not having told her doctor that she was an athlete and in not confirming the contents of the injections.
In a statement released through Universal Entertainment, Nakamura said, "I didn't want anyone to know that I had this kind of gynecological problem, so I didn't tell the doctor that I was an athlete. I wasn't sufficiently conscious of my obligations as an athlete and I'm deeply sorry for what happened as a result."
