When Mimi was three years old, her father took his wife and three young children to Iran. Mimi's father, Tsuneji met another young man - Mr Danishver. They rented a shack and started trading with Japan. They worked very hard. The venture was so successful that the giant Mitsubishi Trading Company asked to join the company. Mimi's father, Tsuneji, became manager of the Middle East division. Tsuneji earned enough money to buy a mansion in Teheran; he hired a maid and lived there happily. Unfortunately a year later, his children became ill. Four-year old Yasuo and his sister Mimi lay dying. Mimi miraculously pulled through, but Yasuo died. Sadly, Mimi's mother died shortly after her brother. The girls' desperate father sent them to a day care operated by French sisters. There Mimi and her elder sister Tami learned to speak French. About a year later Tsuneji decided to go back to Japan with his two daughters. When the family arrived at Kobe in Japan, they were greeted by a pretty woman, Iku, who has designed a dress for Mimi's mother before they had departed for Iran. Tsuneji fell in love with Iku, and the two were married.
Iku was so curious about the Middle East culture that when Tsuneji was assigned to work for Mitsubishi in Baghdad, Iku agreed to go with him. So in 1937, he took his new wife and his two daughters to Iraq and resided in a Suburb of Baghdad. Mimi learned to speak Arabic with her wonderful Iraqi friends. Every summer the family was sent to different places at resort areas overlooking the breathtaking Mediterranean Sea. There they met interesting people who had fled from the Nazis. Great musicians and doctors inspired Mimi's life, and she began to play the piano. In December 1941, the family was ordered by the Japanese government to return to Japan. Soon after, the Pacific war began. The family experienced hunger and cold during the war. Four years after the devastating war, Mimi went to Boston to study music and became a concert pianist.
