Early Life and Background
Maria Nagai was born on December 18, 1996, in Aichi Prefecture to a Japanese father and a Spanish-Filipina mother. This mixed heritage gave her a unique look, making her easily recognizable in the JAV industry.
Despite her mixed ethnicity, Maria retains typical East Asian features—long black hair, dark eyes, and fluent Japanese. This often places her in roles as a Japanese girl with an exotic touch.
Her interest in modeling and fitness became evident during her teenage years. After graduating from high school in 2014, she entered the adult entertainment industry. In 2017, Maria joined a fitness competition and became a finalist in the hip category, shaping her athletic yet curvy body that has since become her trademark.
In 2020, her weight once reached 80 kg with a BMI of 32.5 (class 2 obesity), but this further strengthened her image as a big-breast and big-hip star—something rare in Japan.
Maria grew up in Tokyo and prefers muscular men like bodybuilders. Her hobbies include traveling, cooking, singing, shopping, reading, and listening to music.
