Iwasaki was born as Masako Tanaka to Shigezo and Chie (née Akamatsu) Tanaka. She had ten siblings: brothers Seiichiro, Ryozo, Kozo, Fumio, and sisters Yaeko, Kikuko, Kuniko, Yoshiko, Tomiko, Yukiko. She left home at the age of four to begin studying
traditional Japanese dance at the Iwasaki (geisha house) in the Gion district of
Kyoto. She was legally adopted by the 's owner, Madame Oima, and began using its family name of Iwasaki. Iwasaki became a (apprentice geisha) at the age of 15, and was chosen as the house's , or heir. Iwasaki also received the name "Mineko", as prescribed by a Japanese fortune-teller. By age 16, she had earned a reputation as Japan's most popular and graduated to geisha status on her 21st birthday. According to her autobiography, Iwasaki worked herself to her physical and mental limits, developing at one point a near-fatal kidney condition from which she eventually recovered. Iwasaki entertained numerous celebrities and foreign dignitaries, including the
United Kingdom's
Queen Elizabeth II and
Prince Charles. Iwasaki's fame also made her the subject of jealousy and gossip, and she frequently experienced harassment and assault, often of a sexual nature. After the death of one of her most significant mentors in 1980, Iwasaki became increasingly frustrated with the tradition-bound world of the geisha community, especially inadequacies in the education system. Iwasaki unexpectedly retired at the height of her career, at the age of 29. She hoped that her decision would shock Gion into reform; however, even after over 70 other high ranking geisha followed her into early retirement, nothing was changed. In her autobiography, Iwasaki speculated that the profession could be doomed if the industry failed to adapt to changing economic and social circumstances. She transitioned to a career in art after marrying artist Jin'ichirō Satō in 1982. They had a child, born in 1983. ==
