Princess Ayako is the third youngest daughter of the late Prince Takamado. Prince Takamado is Emperor Akihito’s cousin. As a member of the royal family, Princess Ayako has to leave the imperial household once she marries Kei Moriya.

Since Kei Moriya is a commoner, Princess Ayako will not be allowed to keep her royal status. However, she will receive a bonus payment of $1,000,000. Princess Ayako’s marriage will reduce the number of members of the imperial household to 18.
