Princess Mako met with her grandparents — Emperor Emeritus Akihito and Empress Emerita Michiko — on Monday, a day before her controversial marriage to fiance Kei Komuro.

The 30-year-old princess visited the couple for the first time in 19 months to bid farewell as she is set to register her marriage to Komuro, also 30, on Tuesday morning and leave the imperial household. Their marriage has drawn public controversy over a financial dispute involving Komuro's mother.

The princess, the first grandchild of the former emperor and empress, both 87, arrived at their temporary residence in Tokyo by car at around 10:20 a.m. She opened the window to wave at a group of over 100 people who had gathered along the road.
