Distinguished Professor Emeritus Tsuneko Okazaki is a hero of science. Together with her late husband, Professor Reiji Okazaki, she discovered that DNA replication involves the discontinuous synthesis of the DNA lagging strand by intermediates of, what is now called, "Okazaki fragments." She has been a pioneer for women in science and, in 1983, became the first female full Professor at Nagoya University. From 1997 to 2012, she was a full Professor and later a Visiting Professor at Fujita Health University, and this review zooms in on that period. Besides a summary of her career, this article also includes personal memories of researchers who worked with Professor Okazaki.
