Clad in a dark orange robe only worn by emperors on special occasions, Emperor Naruhito will proclaim his enthronement Tuesday at the Imperial Palace, offering a speech atop a canopied throne followed by banzai cheers from guests.

The 59-year-old monarch — who ascended the throne on May 1 following the abdication of his father, Emperor Emeritus Akihito, the previous day — will formally announce his enthronement from an elevated dais within the palace in Tokyo. The event will be attended by some 2,000 guests from Japan and about 180 countries and international organizations.

The Sokuirei Seiden no Gi enthronement ceremony at the Seiden State Hall will start at 1 p.m. in the Pine Chamber (Matsu no Ma) state room, with the emperor ascending to the 6.5-meter-high canopied takamikura throne. Empress Masako will be seated on the adjacent michōdai throne during the ceremony.
