Michiyo Aratama (新珠 三千代, Aratama Michiyo, birth name Kyoko Toda 戸田 馨子, 15 January 1930 – 17 March 2001) was a Japanese film and stage actress. After graduating from the Takarazuka Music and Dance School, Aratama joined the Takarazuka Revue in 1945. She gave her film debut in 1951, but it was not before 1955 that she left the Takarazuka Revue, signing first with Nikkatsu film studios, then, after her contract expired, with Toho. She worked for directors such as Mikio Naruse, Yasujirō Ozu and Masaki Kobayashi, appearing in films like The Human Condition, The End of Summer, Kwaidan and 47 Ronin. Since the late 1970s, she concentrated solely on stage and television work. Due to health problems, she reduced her appearances after 1994. She died of heart failure in 2001.
