Princess Nori's Marriage and Transition from the Imperial Family
The marriage of Princess Nori marked a significant moment in the modern history of the Japanese monarchy, highlighting the intersection of ancient tradition and contemporary law. On December 30, 2004, the Imperial Household Agency—the government body responsible for the affairs of the imperial family—announced the engagement of the 35-year-old Princess to Yoshiki Kuroda.
Yoshiki Kuroda, born on April 17, 1965, in Tokyo, is an urban designer with the Tokyo Metropolitan Government and a longtime friend of Prince Akishino. The announcement of their engagement faced two delays due to national tragedies: the 2004 Chūetsu earthquake and the passing of Princess Takamatsu.
The Wedding Ceremony and Celebration
The marriage took place on November 15, 2005, at the Imperial Hotel in Tokyo. The event was an intimate affair, with approximately 30 people attending the half-hour marriage rite. The subsequent reception was larger, hosting around 120 guests, including Shintaro Ishihara, the Governor of Tokyo.
The occasion was attended by the Princess's parents, Emperor Akihito and Empress Michiko, along with other members of the imperial family. Outside the venue, thousands of well-wishers gathered along the streets between the royal palace and the hotel to celebrate the couple.

Legal Implications and Change in Status
Following her marriage, Princess Nori underwent a fundamental change in legal status. Under the Imperial Household Law, female members of the imperial family who marry are required to relinquish their titles, official membership in the imperial family, and their state-funded allowance.
By taking her husband's surname, she became the sixth female member born into the imperial family to marry a commoner since the law's passage in 1947. Notably, Yoshiki Kuroda was the first non-aristocratic commoner to marry an Imperial princess. This was also the first time a family member had lost royal status since the 1983 marriage of Princess Masako of Mikasa.
While the law requiring the relinquishment of nobility was repealed in July 2026, it remains unclear if former nobles can be reinstated under this legislative change.
Transition to Private Life
The transition from royal duties to private citizenship required significant personal adjustments. To prepare for her new lifestyle, Princess Sayako reportedly took driving lessons and practiced shopping at supermarkets.
Professionally, she resigned from her position as an ornithologist (a scientist who studies birds) to prioritize her family life. Although she no longer receives an imperial allowance, she received a wedding gift from the Japanese government valued at US$ 1,200,000.
