The sunny streets of Tokyo are already filling up with excited crowds ahead of Emperor Naruhito's enthronement procession. The Emperor and Empress will parade through the heart of the city in an open-top limousine on Sunday afternoon.
People have been gathering around the Imperial Palace since the morning so they can get a good look at the Imperial couple.
Dozens of checkpoints have been set up along the parade route.
After their belongings are inspected, people are being guided to fenced-off areas from where they can offer their best wishes to the new Emperor and Empress.
The Imperial procession was originally planned for October 22 after the Emperor's enthronement ceremony.
But the government postponed it to focus on recovery efforts in areas affected by Typhoon Hagibis.
The parade will start at the Imperial Palace at 3:00 p.m. The Emperor and Empress will make their way in a car to their home on the grounds of the Akasaka Estate.
The route is 4.6 kilometers long.
The parade will last about 30 minutes.
Also taking part are Crown Prince and Princess Akishino, and Prime Minister Shinzo Abe.
The parade will comprise 46 vehicles, including police motorcycles.
Members of the Imperial Guard and the Self-Defense Forces will salute the couple as they pass.
Bands from the Imperial Household Agency, police and other organizations will perform along the route.
The parade is the last of five key ceremonies following the Emperor's accession on May 1.
