Outgoing Japanese emperor Akihito on Tuesday performed the main ritual to hand over the Chrysanthemum Throne to his son Naruhito -- Japan's first abdication in more than two centuries.
Akihito technically remains emperor until the stroke of midnight when the country ushers in the new imperial era of Reiwa, or "beautiful harmony", that will last as long as Naruhito reigns.
In a brief speech, the 85-year-old said he had spent the 30 years of his reign performing his duties with "deep respect and love for the people."
And he offered his "heartfelt gratitude to the people of Japan who accepted me as the symbol of the state and supported me."
Prime Minister Shinzo Abe thanked the emperor, who took the Chrysanthemum Throne in 1989, saying he had "fulfilled his responsibility as the symbol of Japan."
