Tomoko Soryo (Japanese: 惣領智子) is a singer-songwriter from Tokyo. Born in 1952, she started a chorus group in 1971 called Brown Rice which went abroad a year later to perform in the United States. The act broke up in 1975, after which Soryo pursued a solo career. She also formed the duo Tinna with Japanese-American singer Mariko Takahashi (Japanese: 高橋真理子). Soryo has taken breaks from the business over the decades but as of 2002, she's resumed her music work.
