Nobuhiro Watsuki was born in Nagaoka, Niigata prefecture, Japan. When Watsuki was a young boy, his brother, who was three years older, drew manga. Watsuki’s older brother was his role model so he started drawing Manga as well. Watsuki was also inspired by a variety of early Manga artists such as Osamu Tezuka and Fujiko F. Fujio. Later on, his brother stopped drawing manga but, "Because Mr. Watsuki was dumb, he kept drawing it (manga) for a while.” Watsuki describes himself as "pro-dōjinshi" and asks fans to send fan comics.
