In May, Emperor Naruhito and Empress Masako succeeded Emperor Akihito and Empress Michiko, who abdicated for health reasons.
Imperial Japanese enthronement ceremonies consist of a number of ceremonies held during the year. Some of these are state ceremonies, while others are of a more religious nature. Tuesday's ceremony, the Sokuirei-Seiden-no-Gi, was a state ceremony during which the Emperor officially announced to foreign and domestic guests that he had ascended to the throne. The King and The Crown Princess, together with other foreign guests, watched the ceremony from the Shunju-no-Ma Hall.
The ceremony in the state room at the Imperial Palace in Tokyo took place in two octagonal pavilions, holding a throne each for the Emperor and the Empress. The Imperial Couple were both dressed in traditional Japanese royal garments. Following the Emperor's acknowledgement that he had ascended to the throne, Prime Minister Shinzō Abe expressed his loyalty and devotion after which he gave a banzai cheer for the new Emperor.
During the evening, The King, The Crown Princess and other foreign guests attended a Kyoen-no-Gi court banquet hosted by the Imperial Couple at the Imperial Palace. Bugaku – 1,200-year-old court music and dance – was performed during the banquet.
On Wednesday 23 October, The King and The Crown Princess visited Nezu Museum. The museum was opened in 1941, with the aim of preserving and showcasing the pre-modern Japanese and East Asian art collected by businessman Nezu Kaichirō.
Today, the museum's collections include more than 7,000 works: paintings, calligraphy, sculpture, metalwork, ceramics, lacquer, wood and bamboo crafts, textiles, suits of armour and archaeological finds.
During the afternoon, The King and The Crown Princess took part in an imperial tea ceremony together with the new Imperial Couple, other members of the imperial family and invited foreign royal guests.
The tea ceremony took place at the Emperor's private residence, Akasaka Palace.
On the Wednesday evening, The King and The Crown Princess attended a banquet hosted by Japan's Prime Minister Shinzō Abe. During the banquet, the 700 guests watched a traditional Japanese theatrical performance.
On Thursday 24 October, The King visited the Isseido antiquarian bookshop in Tokyo. The shop has been owned by the same family since it opened in 1913, and is currently run by Takehiko Sakai.
One of the books that The King looked at was Carl Peter Thunberg's Voyages de CP Thunberg au Japon. Thunberg was a Swedish botanist and a student of Carl Linnaeus during the 18th century. At that time, only the Dutch were allowed to visit Japan. However, as a surgeon employed by the Dutch East India Company, Thunberg was able to travel to Japan in 1775-1776. There, he was one of few people to be permitted to carry out botanical research.
On the Monday, The Crown Princess visited employees at the Swedish Embassy in Tokyo. Staff from Business Sweden and the Chamber of Commerce were also in attendance. The Crown Princess was then given a tour of the Imperial Palace. The palace has been the residence of the emperor since 1868, before which Kyoto was the imperial capital for more than a thousand years.
In the evening, Ambassador Pereric Högberg invited The King and The Crown Princess to dinner at his official residence. During the dinner, The King and The Crown Princess learnt about the current situation in Japan.
Japan is the world's oldest monarchy, with roots dating back to the 6th century AD. The new Emperor Naruhito is the country's 126th emperor, and when he succeeded his father in the spring it was announced that the new era would be called Reiwa ('beautiful harmony').
The Chrysanthemum Throne is often used as a metonym for the monarchy of Japan.
