In 1954 she received her undergraduate degree from Kyoto University in French literature, with a senior thesis on Charles Baudelaire.
She supported him in the first two years of their marriage by a series of odd jobs, then returned to Kyoto University in 1956 to receive a master's degree in French literature in 1958 for a thesis on François Mauriac.
Her husband won a major literary award in 1962, making his name and providing sufficient funds so that Takahashi could quit her job, work on her novel, and publish a translation of Mauriac's Thérèse Desqueyroux.
In 1972, she received the Tamura Toshiko Literary Award for Sora no hate made (“To the end of the Sky”).
She subsequently won the Women's Literature Award in 1977 for a set of linked short stories titled Ronri Uman (“Lonely Woman”) and the Yomiuri Prize for Ikari no ko (“Child of Rage”) in 1985, and the Mainichi Art Award for Kirei na hito (“Pretty person”) in 2003.
