Sugita was born in Ranzan, Saitama. When he was in elementary school and watched the TV anime Dragon Quest: The Adventure of Dai, he noticed that the character Hyunckel had a much lower voice than he had imagined from reading the original manga, and thought he was "still cool," but the moment he said his special move, Sugita realized that it was the same voice as Phoenix Ikki from Saint Seiya (Hideyuki Hori). In junior high school, he was a member of the tennis club and served as the head of the club, while in high school, he joined the Shorinji Kempo club (1-dan). When he was a child, he wanted to be a temple priest, and in high school he wanted to be a home economics teacher, a confectioner, or a designer. At the time, when he thought about writing a script for a stage performance at a school event and added sound effects and background music to a recording of his own voice, his older brother heard it and suggested that he try to find a job that made use of him voice and speech, which led him to become a voice actor. While still in high school, he won the Myuras & Animage Award at the Voice Actor Spring School sponsored by the Japan Narration Actor Institute, and entered the Myuras Actors School (now the Vocal and Dance Division of the Japan Narration Actor Institute), while at the same time belonging to the Myuras entertainment agency. At the age of 17, he made his voice acting debut as a gift announcement narrator for Kamen Rider on SKY PerfecTV!.
In 1999, when he was a prep school student, he got his first regular role in an anime production with Cybuster, and continued his voice acting career while studying until he graduated from university. After the dissolution of Myuras in 2001, he joined Atomic Monkey after a period of freelancing, and made his first leading role playing Hideki Motosuwa in the anime series Chobits.
Sugita played the leading roles in both Gintama (Gintoki Sakata) and The Melancholy of Haruhi Suzumiya (Kyon), greatly increasing his fame.
