Years from now, Monaco’s Prince Jacques and Princess Gabriella may recall their 2019 visit to Japan as the family trip that included a local school visit, toy shopping and that time “Dad took us to Disneyland — and left us there.”

The royal twins, who turn 5 in December, were “unofficial” entourage members during Prince Albert’s voyage to the enthronement of Japan’s Emperor Naruhito. Their presence during the 12-day long visit was intentionally kept away from the press with only the briefest sightings, largely on social media.
