Appearance
Nao is tall with a slender and toned build. He has droopy lime green eyes and long gray hair with bangs that dip between his eyes. He is usually seen wearing a mild expression. After graduating junior high school, he wears corrective lenses and his hair is shorter.

Personality
Nao is a gentle, patient, and soft-spoken individual with keen insight into the motives of others and a logical approach to life. His empathetic nature helps him motivate the students he coaches, as seen when he works with Haruka and his teammates, identifying their individual obstacles to improvement, then helping each one develop for themselves a strategy to overcome them. He is a loyal friend to Natsuya Kirishima.

History
Nao is a third-year at Iwatobi Junior High School when Makoto and Haruka enter as first-years. He is the co-captain and manager of the school's swimming club and president of the library committee, as revealed in the light novel. In High☆Speed！－Free! Starting Days－ it is revealed that he goes through an eye surgery. Temporarily unable to swim due to health issues, his tolerant nature allows him to channel his frustration into coaching and solidifies his career choice of sports medicine.

In Free! The Movie -Take Your Marks-, Natsuya tells the junior high team that he doesn't swim due to said injury, adding that he wishes they could swim swim together again, someday, but must wait until Nao is medically permitted to do so. Nao goes on to attend Soufukan High School, graduating and moving to Tokyo, where he studies at Oudoukan University. In an ironic twist, he is the previous owner of the apartment in which Haruka currently lives and becomes the catalyst in Makoto's own career path of professional training/coaching.
