Princess Nori, the only daughter of Emperor Akihito and Empress Michiko, will marry Yoshiki Kuroda, an official in the Tokyo Metropolitan Government, a senior Imperial Household Agency official said Sunday.

An official announcement will be made in late December in line with the wishes of the 35-year-old princess, whose other formal name is Sayako, and the 39-year-old Kuroda, said Shingo Haketa, vice grand steward of the Imperial Household.

The Emperor and Empress have approved the marriage, he said, adding that the wedding will be held as early as this spring. With the marriage, Princess Nori will become a commoner.
