From June 1998 to March 2000, she was part of the ISS Centrifuge team (life science experiment facility) conducting conceptual framework and preliminary design.

Yamazaki was selected as an astronaut candidate in February 1999 by the National Space Development Agency of Japan (NASDA, now JAXA), attended the ISS Astronaut Basic Training program beginning in April 1999, and was certified as an astronaut in September 2001.
