Kyariaūman
A is a Japanese term for a career woman, that is, a Japanese woman, married or not, who pursues a career to make a living and for personal advancement, rather than being a housewife without occupation outside the home. The term came into use when women were expected to marry and become housewives after a short period working as an " office lady".
"Career woman" is used in Japan to describe the counterpart to the Japanese salaryman ; i.e., a woman who works for a salaried living. These Japanese women seek to either supplement their family's income through work or to remain independent by seeking a career as a working woman.
