Masaaki Endoh (遠藤正明) is a Japanese singer born on August 28, 1967, in Ishinomaki, Japan, best known for his powerful voice and his work in anime music. Active since the late 1990s, he has built a reputation as one of the most recognizable performers in the anison scene, with a style that combines intensity, technical control, and a strong sense of melody. His solo career and broader catalog are also associated with j-pop and singer-songwriter sensibilities, alongside the rock-driven sound that has made him a familiar name in Japanese pop culture.
Endoh is also known as a member of JAM Project, the high-profile anime song supergroup associated with many action and mecha titles. Through that project and his solo work, he has become closely identified with theme songs that call for dramatic arrangements, soaring vocals, and a performance style designed to match the energy of anime openings and endings. He is signed to Lantis, and his work continues to explore the wider world of anime and game music while maintaining the vocal power that made him stand out early in his career. His performances are often appreciated by listeners who look for emotionally direct, high-impact songs rooted in Japanese pop and rock-based anime music.
