Mirai Aileen Nagasu (長洲 未来, Nagasu Mirai, born April 16, 1993) is a Japanese- American figure skater. She is a three-time Four Continents medalist (silver in 2016, bronze in 2011 and 2017), the 2007 JGP Final champion, a two-time World Junior medalist (silver in 2007, bronze in 2008), and a seven-time U.S. national medalist (gold in 2008, silver in 2010 and 2018, bronze in 2011 and 2014, pewter in 2016 and 2017).
In 2008, Nagasu became the youngest woman since Tara Lipinski in 1997 to win the U.S. senior ladies' title, and the second-youngest in history. She is the first lady since Joan Tozzer in 1937 and 1938 to win the junior and senior national titles in consecutive years. Nagasu represented the United States at the 2010 Winter Olympics at the age of 16 and placed 4th in the ladies' event. In 2017, she landed the very difficult triple Axel jump for the first time in international competition at the US International Figure Skating Competition. During her free skate in the team event at the 2018 Olympics, she became the first American female figure skater to land a triple Axel at the Olympics, and the third woman from any country to do so.
