Satoko Kitahara (北原 怜子, Kitahara Satoko, 22 August 1929 – 23 January 1958) – later known as Elisabeth Maria Kitahara – was a Japanese Roman Catholic. Kitahara was descended from aristocrats and samurai warriors; she worked in an airplane warehouse during World War II and became disillusioned after she and others learnt of Japanese atrocities during the conflict. She discovered Roman Catholicism and after a period of being exposed to churches decided to learn catechism so she could be baptized.
