Koshi Inaba (稲葉浩志) is a Japanese singer-songwriter best known as the vocalist and lyricist of the rock duo B’z, one of Japan’s most commercially successful acts. Alongside his work with B’z, he’s also built a solo career, releasing his own material and performing live under his own name, with a style that often leans into hard rock but leaves room for melodic, reflective moments.
Outside of music, Inaba is also known for being relatively private, letting his voice and performances do most of the talking. Whether fronting B’z on massive stages or delivering solo tracks with a more personal edge, he’s widely recognized as one of the defining rock vocalists in modern Japanese music.
