Emperor Naruhito and Empress Masako Dine with Netherlands' Future Queen, Signaling Europe's Female Monarchy Era

Emperor Naruhito and Empress Masako of Japan attended a state dinner hosted by King Willem-Alexander and Queen Máxima of the Netherlands on June 17, 2026. The imperial couple was seated beside Princess Catharina-Amalia, 22, the heir to the Dutch throne and the country's future queen. During the dinner, the emperor and empress engaged in conversation with the princess, which also touched upon the current circumstances of their own daughter, Crown Princess Aiko, who is the same age. The dinner marks a symbolic moment as both the Netherlands and Belgium prepare for transitions to female-led monarchies, with Princess Catharina-Amalia set to become queen and Princess Elisabeth, 24, heir to the Belgian throne, expected to greet the Japanese imperial couple during their subsequent visit to Belgium. Dutch Ambassador to Japan Pruiff noted that the princess has strengthened public expectations for her future role as queen through her participation in military training at the National Defence University and other official duties, demonstrating both her preparedness and commitment to the role. The event reflects a broader shift in European society toward accepting women in royal succession, occurring amid ongoing discussions in Japan regarding its own imperial succession.
