Hideki Kaji (加地秀基) is a Japanese singer-songwriter and musician born on May 8, 1967, in Futtsu, Japan. Active since the 1990s, he became associated with Japan's Shibuya-kei and indie-pop circles, where stylish arrangements and memorable melodies are central to his work.
Kaji's music blends indie pop, soft rock, bossa nova, and lounge-pop textures, giving his songs a relaxed but carefully constructed character. Rather than relying on big, dramatic production, he favors clean arrangements, light instrumentation, and hooks that linger. Released through Trattoria Records, his catalog reflects an interest in atmosphere as much as songwriting craft, balancing warmth and precision across a career rooted in melodic Japanese pop. In 2026, he also teamed up with former Tsubaki Factory member Yume Kishimoto on the song "渾身CRAZY FOR YOU!!", for which he composed the music.
