Kaoru Otsuki
Biography. Kaoru was born in Yokohama, Kanagawa Prefecture, Japan, on 6 August 1888. Kaoru first met Sun Yat-sen in Yokohama's Chinatown in 1898 when she knocked over a vase and had to apologize to Sun Yat-sen. In 1901, Sun asked Kaoru's father for permission to marry his daughter, but Kaoru's father refused because of the great age difference between Sun and Kaoru (at the time, Sun was 37 while Kaoru was only 13). One year later, Sun Yat-sen proposed marriage again and Kaoru's father relented. Kaoru and Sun's wedding ceremony  was held in Yokohama in 1903. At the time, Sun was still married to his first wife, Lu Muzhen. Kaoru gave birth to her and Sun's daughter, Fumiko, on 12 May 1905; however, Sun had already left Japan by then and never returned to see his daughter. Kaoru later remarried twice, while Fumiko was adopted by a family surnamed Miyagawa. Fumiko did not learn of her father's real identity until the 1950s.
