"Satchin and His Brother Mabo" is a photographic series by Nobuyoshi Araki, created between 1963 and 1965. It depicts two young boys, Satchin and Mabo, in various candid and everyday settings, primarily in Tokyo. This early work is notable as it showcases Araki's emerging style and his interest in capturing the lives of ordinary people, a theme that would continue throughout his career. The series is considered a precursor to his later, more well-known works, including "Sentimental Journey".
