Tomiko Satō (佐藤 富子, Satō Tomiko, 1894-1995) was the common-law wife of the Chinese Communist scholar and poet Guo Moruo. She is often referred to in Chinese sources as Anna (安娜), the way Guo Moruo called her. Satō Tomiko spent about 20 years with Guo, in Japan and in China, until they were separated by the war, and they had five children together.

Tomiko Satō was the eldest of eight children in the family of a Japanese Protestant minister in the Ohira village, Kurokawa District, Miyagi Prefecture (north-eastern Honshū). In her teens she studied at a Baptist boarding school in Sendai, the capital of the prefecture. At 21, rebelling against the prospect of an arranged marriage, she left her home prefecture and went to Tokyo, where she found a job with St Luke's Hospital as a student nurse.

Satō's relationship with Guo Moruo started in the summer of 1916, about a year after her arrival to Tokyo. A friend of Guo, named Chen Longji (陈龙骥), happened to be treated for tuberculosis at St Luke's Hospital. Guo, who had just completed his first year of study in Japan, visited his sick friend in the hospital on his trip to Tokyo, but the patient died soon. After the death of his friend, Guo met her when visiting the hospital to request the dead friend's X-ray records. Satō was sharing Guo's grief over the death of his friend, and once Guo returned to Okayama, they started regularly exchange letters. By December, Guo Moruo convinced Satō to leave Tokyo and join him in Okayama.

Satō and Guo had their first child, a son, in December 1917.

Satō and Guo's union was vehemently opposed by both of their families, and ill-received by the community they were in.

In April 1923, Satō moved with Guo and their three children to Shanghai. They had financial difficulties, and in February 1924 she went to Japan, taking the children along, but returned to Shanghai in mid-November.
