Maiko Sato

is a Japanese former sailor, who specialized in both Europe and Laser Radial classes. She captured a silver medal in her respective single-handed boat category at the 2002 Asian Games in Busan, South Korea, and was also selected to compete for Japan in two editions of the Olympic Games (2000 and 2004).

Sato made her Olympic debut in Sydney 2000, where she finished twenty-third in the Europe class with a satisfying net grade of 172, surpassing Belarusian sailor Tatiana Drozdovskaya by a close, four-point margin.

When South Korea hosted the 2002 Asian Games, Sato sailed away vigorously towards a silver-medal finish in the Europe class with a grade of 16 points, an exact double of the score attained by her Chinese rival and eventual champion Lu Chunfeng. As her previous Games, Sato could not be able to improve her Olympic feat with mediocre marks recorded throughout the eleven-race series, sitting her in twenty-fourth position with 192 net points. Furthermore, Sato's overall score spared her from the far bottom of the leaderboard by a twelve-point edge over the Russian rookie Natalia Ivanova.
