In 2001, Princess Masako gave birth to a girl, Aiko, who according to law cannot ascend the throne.
Princess Masako, whose sole purpose is to produce an heir to the throne, is not.
Princess Masako will turn 38 in just over one week.
Eight years later, many Japanese say that Princess Masako has played a far smaller role than they anticipated.
In January Princess Masako bowed out of all public functions, starting a seclusion that continues to this day.
Princess Masako, Japanese say, at least has the advantage of a supportive and sympathetic mother-in-law.
Princess Masako's assertion that she was not depressed came as she criticized the press, especially the foreign press, for exaggerating her problems.
Then, well after nightfall, came the news that Princess Masako had suffered a miscarriage and undergone surgery.
The birth may also end the psychological drama surrounding the royal family, especially Princess Masako.
Princess Masako did not elaborate on what sort of "hardship" she has suffered, but she did display annoyance at the reports.
