Japanese Emperor Naruhito formally proclaims his enthronement in 'Sokui no Rei'

Naruhito became emperor in May in a brief, tradition-filled ceremony but Tuesday's "Sokui no Rei" was a more elaborate ritual at the royal palace in which he officially announced his change in status to the world.

The first Japanese emperor born after World War Two, Naruhito acceded to the throne when his father, Akihito, became the first Japanese monarch to abdicate in two centuries after worrying that advancing age might make it hard to perform official duties.
 

The long-planned celebrations were tempered by Typhoon Hagibis, which killed at least 80 people when it tore through Japan 10 days ago, and pouring rain on Tuesday.

A public parade was postponed until next month to allow the government to devote its attention to the typhoon clean-up, while Tuesday's inclement weather forced the palace to scale back the number of courtiers in ancient robes taking part in the courtyard ceremony although the skies cleared as it began.

Naruhito began the day's ceremonies by reporting his enthronement to his imperial ancestors at one of three shrines on the palace grounds, dressed in a black headdress and pure white robes with a long train borne by an attendant.

He was followed later by his wife, Empress Masako, 55, dressed in a 12-layered white robes and attended by two women in violet robes to arrange her train.

For the main ceremony in the Matsu-no-Ma, or Hall of Pine, the most prestigious room in the palace, Naruhito wore a traditional burnt-orange robe and headdress, as his father did nearly three decades ago.

He declared his enthronement from the "Takamikura" - a 6.5-metre high pavilion that weighs about 8 tonnes - with an ancient sword and a jewel, two of the so-called Three Sacred Treasures, placed beside him.

Together with a mirror called Yata-no-Kagami, which is kept at the Ise Grand Shrine, the holiest site in Japan's Shinto religion, the three treasures comprise the regalia that symbolises the legitimacy of the emperor.

Masako, wearing 12-layered robes and an elaborate, upswept hairstyle, also took part, her throne smaller.

Prime Minister Shinzo Abe delivered a congratulatory speech before guests including Prince Charles, who with then-wife Princess Diana attended Akihito's enthronement, as well as US Transport Secretary Elaine Chao and Myanmar civilian leader Aung San Suu Kyi.

Abe then led the assembled dignitaries in giving three "banzai" cheers for the Emperor.

A court banquet is due to be held on Tuesday evening, before Naruhito and Masako host a tea party for foreign royalty on Wednesday afternoon.

While the public parade was postponed until November 10, the NHK national broadcaster said there were 26,000 police providing security on Tuesday.
 

Naruhito is unusual among recent Japanese emperors since his only child, 17-year-old Aiko, is female and as such cannot inherit the throne. The future of the imperial family for coming generations rests instead on the shoulders of his nephew, 13-year-old Hisahito, who is second in line for the throne after his father, Prince Akishino.

Naruhito's grandfather, Hirohito, in whose name Japanese troops fought World War Two, was treated as a god but renounced his divine status after Japan's defeat in 1945. Emperors now have no political authority.
