Crown Princess Masako met on Wednesday afternoon with her father, Hisashi Owada, a judge at the International Court of Justice in The Hague, and mother, Yumiko.
Owada told reporters he and his wife talked over tea with their daughter and Crown Prince Naruhito at the royal couple's hotel. He said they seemed to be relieved after attending the coronation of the new Dutch king on Tuesday, while expressing gratitude to the Netherlands for the invitation.
The Crown Princess is on her first official overseas trip in 11 years after struggling with a stress-induced illness. Owada became a judge at the court in 2003 after serving as the top bureaucrat in the Foreign Ministry.
The Crown Prince and Princess also met with Kuniko Ozaki, a judge at the International Criminal Court, who was a senior colleague of the Crown Princess when she was a diplomat in the Foreign Ministry, and harpist Masumi Nagasawa, with whom they are acquainted, the Imperial Household Agency said.
The Crown Prince invited 27 Japanese professionals in the Netherlands, including Ozaki and Nagasawa, to the hotel.
The couple also met with about 30 staff members at the Japanese Embassy to thank them for preparing their visit.
