Musical style

His songs are often modeled on friends and acquaintances or built from conversations with them, and he posts self-written liner notes online. He grew up hearing Miyuki Nakajima, Takuro Yoshida, George Yanagi and RC Succession on his parents' records, and says they shaped his music. Watching films is his hobby and often inspires his writing. Producer Junji Ishiwatari described his sound as having modern arrangements with melodies and lyrics deeply influenced by classic Japanese kayokyoku.
