Empress Masako is going to be disappointed, and her plans to go to England may change, and Charles Kate is sick
If the Japanese royal family has the best relationship in the Asian royal circle, the two Bhutanese royal families and the Thai royal family, then looking at the European royal circle, the most ironclad relationship must be the British Windsor royal family. The British royal family is the most famous in the world, and the Japanese royal family has been in frequent contact with the Windsor family for many years. If the children of the Japanese royal family want to study abroad after completing university, there is no doubt that the UK is the first choice.
Emperor Naruhito went to study at Oxford University after graduating from the Gakuin, and Empress Masako went to England to continue her studies after working at the Ministry of Foreign Affairs for two years. Both of them have a different kind of affection for the UK, and at the same time, they deeply miss the good times in the UK. 
When Emperor Naruhito was studying abroad, Queen Elizabeth often invited him to Buckingham Palace as a guest, and Charles, the then crown prince, also formed a deep friendship with Naruhito. In 2019, Emperor Naruhito ascended the throne and changed the Yuan Reiwa, and the British royal family was also congratulated by Charles himself. 
The relationship between the two families is so deep that after Naruhito ascended the throne, there have always been plans to arrange for the emperor and his wife to visit the United Kingdom officially, meet the queen, and go to Buckingham Palace for a party. It was originally scheduled for 2020, but it was later cancelled.
In September 2022, Queen Elizabeth died at the age of 96, and the Japanese royal family also went to London with Naruhito and Masako to attend the funeral. At the queen's grand funeral ceremony, the emperor and his wife both appeared in black solemn formal suits, and the etiquette was very well done.
The coronation ceremony of Charles in 2023, according to the reciprocal etiquette of the crown prince's upgrade, was congratulated by the crown heirs, Prince Fumihito and Princess Kiko. But at that time, the Imperial Household Agency said that it would arrange for Naruhito and Masako to visit the United Kingdom in 2024.
According to Japan's ** "Women's Weekly", Empress Masako may be disappointed again. The Imperial Household Agency initially decided to arrange for the couple to go to the UK in May 2024, but now that the British royal family is also in a mess, I am afraid it is not a good time to visit.
The two main members of the British royal family, King Charles and Princess Kate, are both ill. The 73-year-old Charles was found to have cancer during a physical examination, and now he has put aside all his royal duties to concentrate on recuperating at the Sanderlin Manor. In the future, King Charles will often run to the hospital when necessary, and he will often be powerless for royal affairs, and he will be handed over to his eldest son, Prince William.
And Crown Princess Kate has disappeared from public view since Christmas at the end of last year. Last month, the British royal family admitted that Kate had undergone abdominal surgery, and after a few weeks of rest in the hospital, she has now been taken home to recuperate. But Kate hasn't posted a ** so far, which makes people worry about what her ** situation is.
The British royal family did not say very clearly when Kate would return, only that it would probably be Easter, but there would be a new situation at any time. The outside world even speculated that Kate would actually need 9 months.
In such a chaotic and busy time, if the Emperor and Empress of Japan were to go to England, the royal family should be properly prepared and welcomed. But in this case, they have neither the heart nor the manpower to entertain the guests.
Therefore, the Imperial Household Agency is already secretly revising and adjusting, and Empress Masako's long-awaited visit to the United Kingdom is facing a backup plan that will be postponed or canceled.
Despite her mixed feelings, Empress Masako herself has been plagued by health problems for many years, and her adjustment disorder has never been cured. She has experienced the pain of illness firsthand, so she can also better appreciate the importance of health problems and recuperation. As King Charles said in his first statement after announcing that he had cancer, "Thank you very much for your strong support and kindness", and Queen Masako Xiangbi is also concerned.
