皇室典範
On 30 December 2004, the Imperial Household Agency announced the engagement of the 35-year-old Princess Nori to the 39-year-old Yoshiki Kuroda (黒田慶樹 "Kuroda Yoshiki"). Born in Tokyo on 17 April 1965, he is an urban designer with the Tokyo Metropolitan Government and a longtime friend of Prince Akishino. Upon her marriage, which took place at the Imperial Hotel, Tokyo on 15 November 2005, Princess Nori left the Imperial Family, taking the surname of her husband; he became the first non-aristocratic commoner to marry an Imperial princess. This change in her status is mandated by the Imperial Household Law that requires females of the imperial family who marry to relinquish their title, official membership in the imperial family, and allowance from the state. She became the sixth female member born into the Japanese imperial family to marry a commoner since the passage of the Imperial Household Law in 1947, and the first member of the family to lose royal status since the marriage of Princess Masako of Mikasa, one of Emperor Akihito's cousins, in 1983.
