Tetsuji Hayashi, born on 20 August 1949 in Fuji, Shizuoka, is a Japanese composer, singer-songwriter, and arranger known for his contributions to J-pop and city pop. From an early age, he was exposed to Western pop music, which sparked his passion for composing. He began his musical journey by attending the Yamaha Music School and later editing the Yamaha music magazine Light Music. In 1973, he debuted as a singer-songwriter with the release of his album BRUGES, following the success of his song "Sore ga Koi no Owari Nara" at the Third World Popular Song Festival in Chile. His early career included collaborations with notable artists such as Mariya Takeuchi and Miki Matsubara, composing hits like "September" (1979) and "Mayonaka no Door" (1979). His work extended to other prominent figures, including S. Kiyotaka & Omega Tribe, Masaki Ueda, and Junichi Inagaki. Throughout the 1980s, he continued to produce influential music, contributing to soundtracks for films like Hachikō Monogatari (1987). Despite plans to retire in 2008, fan support led him to return to composing and producing music. His legacy was celebrated with the release of the compilation album 50th Anniversary Special A Tribute of Hayashi Tetsuji: Saudade in 2023, accompanied by a concert showcasing his impact on Japanese pop music.
