Emperor Naruhito and Empress Masako of Japan conducted an official state visit to the Netherlands, highlighted by a reunion with the Dutch royal family.
The visit serves to strengthen diplomatic ties and maintain a long-standing family friendship between the Japanese Imperial Household and the Dutch Royal Family. The diplomatic engagement emphasizes the personal bonds that often underpin formal international relations.
Among the key events was a dinner hosted by King Willem-Alexander and Queen Máxima. A significant moment of the visit occurred on June 20, 2026 [2], when Crown Princess Aiko reunited with Princess Catharina-Amalia. The two had not held hands in 20 years [1]. Princess Catharina-Amalia is currently first in line for the Dutch throne [1].
The Imperial party also spent time at Het Oude Loo Castle. Emperor Naruhito said the experience of visiting the castle with Empress Masako and Princess Aiko was a "wonderful summer holiday."
Reports indicate the state visit began on June 13, 2026 [3]. The itinerary included various formal engagements and private interactions designed to foster cooperation between the two nations. The reunion between Aiko and Amalia, who were childhood acquaintances, provided a personal narrative to the official state proceedings.
“The two had not held hands in 20 years.”
This state visit leverages the personal history between the Japanese and Dutch royal families to soften the edges of formal diplomacy. By highlighting the childhood connection between Princess Aiko and the future Queen of the Netherlands, both nations project an image of stability and enduring friendship that transcends political cycles.
