To this day, Japan is home to a large population of so-called “zainichi Koreans,” who can trace their ancestry back to Japan’s decadeslong occupation of Korea, before and during World War II. Musician Sasami Ashworth grew up in the US, but this history and her family upbringing echoes in her music.
