In Oslo, the Royal Household of Norway has announced that His Royal Highness Crown Prince Haakon of Norway will shorten his forthcoming official visit to Japan due to the health condition of Her Royal Highness Crown Princess Mette-Marit of Norway.

According to the Royal Household, the Crown Prince will maintain his official program in Tokyo from June 1st through June 3rd, while the scheduled visit to the port city of Hachinohe on June 4th has been cancelled.

The Crown Prince had originally been scheduled to undertake an official visit to Japan from June 1st through June 4th.

In October 2018, the Royal Household of Norway announced that Crown Princess Mette-Marit had been diagnosed with chronic pulmonary fibrosis, a progressive lung disease characterized by scarring of lung tissue that can gradually impair respiratory function and breathing capacity.

Since November 2025, the number of official engagements carried out by the Crown Princess has been reduced significantly as a consequence of her health condition. 

Crown Princess Mette-Marit made a brief public appearance during Norway’s National Day celebrations on May 17th, 2026, and also attended a reception honoring Norwegian athletes who participated in the Milano Cortina Paralympic Games earlier this year.
