Mitsu Yashima
was an artist, children's book author, and civic activist. Life Mitsu was the daughter of a shipbuilding company executive. She attended Kobe College, and later enrolled at Bunka Gakuin in Tokyo. In the 1930s, she joined a Marxist study group, where she met her future husband, artist Taro Yashima. She and her husband painted farmers and laborers, and participated in exhibitions of art that critiqued Japan's military expansion and the government's increasingly heavy handed suppression of dissent. She and her husband were later imprisoned and brutalized by the Tokkō (special higher police) in response to their antiwar, anti-Imperialist, and anti-militarist stance in the 1930s. Their lives from this time are depicted in her husband's picture books, published in English, The New Sun and Horizon is Calling. Mitsu and Taro's son Makoto Iwamatsu was born in 1933. He would eventually become a renowned actor and voice actor. In 1939 she and Taro went to America so that Taro could avoid conscription into the Japanese Army and to study art. After the attack on Pearl Harbor, Mitsu joined the U.S. war effort, working for the Office of Strategic Services by sending American propaganda to the Japanese. She adopted the pseudonym Mitsu Yashima
