In his childhood, Naito was a quiet kid who loved manga. One of his favorite titles was Doraemon, and during his martial arts career, he earned the nickname “Nobita” because of his resemblance to the lead character in the Doraemon manga. Naito didn't practice any martial arts as a child, but was a member of the soccer club in junior high school. He had few friends during his adolescence and struggled with his grades in school. He later dropped out of high school, a short-sighted decision he later said he regretted. Naito fell in love with mixed martial arts in the early 2000s. He loved watching Kazushi Sakuraba, who he calls his martial arts hero. He was fascinated by the submissions Sakuraba was able to pull off against foreign athletes in Pride Fighting Championships and soon found himself training at Paraestra Matsudo. He was invited to train at Paraestra Matsudo by his brother Nobutaka. His brother is also a mixed martial artist, currently competing with Shooto.
