Japan's imperial palace said Princess Mako's formal engagement and wedding to her college sweetheart is being postponed until 2020.
She and her fiance, Kei Komuro, who's a commoner, were scheduled to tie the knot in early November. Mako is the granddaughter of Emperor Akihito; he's stepping down from the throne next year.
With Akihito's abdication and his oldest son's accession to the throne coming up, Japanese media report Mako and her fiance decided to postpone the festivities after realizing they didn't have enough time to prepare.
In a statement, the princess contributed the postponement to the couple's immaturity and apologized for the delay. Mako will lose her royal status once she's married.
