In the 1890s, Mitsuko Aoyama became one of the first Japanese people ever to immigrate to Europe when she accompanied her husband, the cosmopolitan diplomat Heinrich Johann von Coudenhove-Kalergi, on his return to Austria-Hungary. At the time, Japan was just beginning to open up to the rest of the world. The empress personally conveyed her wish that Aoyama, the daughter of a highly respected Japanese antiques dealer, should bring honour to her native country. Aoyama gave birth to seven children and raised them in accordance with Austrian customs. In 1906, her life changed dramatically when her husband Heinrich died unexpectedly at the age of just 47. The 32-year-old suddenly found herself alone and responsible for guiding her family through turbulent times. Following defeat in the First World War the Austro-Hungarian Empire ceased to exist, and Aoyama would live to see the outbreak of the Second World War. Her son, Richard Coudenhove-Kalergi, became the founding president of the Paneuropean Union, the oldest European unification movement still in existence. Mitsuko lived a quiet life with her eldest daughter in Mödling, a small town just outside Vienna, until her death in 1941. Now, this new documentary examines Mitsuko Aoyama’s highly unusual life story and relates how she became a figurehead for female emancipation who remains revered in Japan to this day.
