Oshima [born Yukari Tsumura, December 31 1963, in Japan] became a stuntwoman
with Sonny Chiba's JAC (Japan Action Club) in 1980. After minor roles
in Japanese TV, Yukari changed her name from Tsumura to Oshima and moved
to Hong Kong for a small part in Sammo Hung's "Shanghai Express" (1986).
Another 25+ films followed. A marriage to actor Mark Cheng in 1982 ended
in a messy divorce 5 years later. Ms Oshima started making more films
in the Philippines and moved there in 1988 where she starred in another
20+ as Cynthia Luster. Yukari has since gone into semi-retirement, now
residing in her hometown of Fukuoka, Japan, where she is actively involved
in promoting tourism for her city.
