Many, if not most of Yamaguchi's voice roles are teenagers or even younger boys. He is well-known for his ability to perform high-pitched, "young" voices. This is especially noticeable in BL dramas/games. His characters are also generally straightforward-minded, sometimes simple-minded, humorous and easily excitable but usually "good" characters.
