Japan’s Emperor Akihito has abdicated at the age of 85 in a historic ceremony at the Imperial Palace in Tokyo.

In his last public address as emperor, the emperor handed over the symbols of power and thanked the public for their support during his 30-year reign.

He was given permission to abdicate after saying he felt unable to fulfill his role because of his age and declining health.

Akihito is the first Japanese monarch to stand down in more than 200 years.

He technically remained emperor until midnight, local time.

Crown Prince Naruhito, the emperor’s eldest son, formally ascends the throne on May 1. A new era – called Reiwa, meaning order and harmony – will begin in Japan’s unique calendar.

While the Japanese emperor holds no political power, he serves as a national figurehead.

Akihito has endeared himself to many people during his reign as he has interacted with those suffering from disease and disaster.

In the morning, Akihito took part in a Shinto ceremony to report his plans to the mythological ancestors of Japan’s imperial family.

The main “Ceremony of the Abdication” took place in a state room of the Imperial Palace in front of about 300 people including PM Shinzo Abe, Crown Prince Naruhito, and Crown Princess Masako.

Imperial chamberlains carried the state and privy seals into the hall, along with a sacred sword and a jewel which are considered symbols of the imperial family.

In a short ceremony, PM Shinzo Abe addressed the emperor, saying: “While keeping in our hearts the path that the emperor has walked, we will make utmost efforts to create a bright future for a proud Japan that is full of peace and hope.”

In his final speech as emperor, Akihito said: “I am deeply grateful for the people that accepted me as a symbol and supported me.”

“I sincerely wish, together with the empress, that the Reiwa era which begins tomorrow will be a stable and fruitful one,” he added.

“I pray, with all my heart, for peace and happiness for all the people in Japan and around the world.”

Emperor Akihito had surgery for prostate cancer in 2003 and a heart bypass operation in 2012.

In a rare speech in 2016, he said that he feared his age would make it hard for him to carry out his duties and strongly hinted that he wanted to stand down.

Opinion polls showed that the vast majority of Japan sympathized with him, and a year later parliament enacted a law that made his abdication possible.

Crown Prince Naruhito, 59, will become Japan’s 126th emperor – and will officially lead the country into the new Reiwa era. It will mark the end of the current Heisei era, which began when Akihito ascended the throne in 1989.

Naruhito, an Oxford University graduate, is married to Crown Princess Masako. Their only child, Princess Aiko, was born in 2001.

Japan’s current law prohibits women from inheriting the throne, so Princess Aiko’s uncle Prince Fumihito is now first in line, followed by her cousin, 12-year-old Prince Hisahito.

Japan’s monarchy is the oldest continuing hereditary monarchy in the world. Legends date it back to about 600 BC.

The emperors used to be seen as gods, but Hirohito – the father of Akihito – publicly renounced his divinity as part of Japan’s surrender at the end of World War Two.

It was Emperor Akihito who helped repair Japan’s post-war reputation.

Previous emperors rarely interacted with the public, but Akihito redefined the role – and has come to be known for his compassion.

He also took up the role of a diplomat, becoming an unofficial ambassador for Japan and travelling abroad extensively.

While Akihito’s abdication was the first in 200 years, it wasn’t so rare historically.

According to Japan’s state broadcaster NHK, about half the emperors or empresses have done the same, and it happened frequently from the 8th Century to the 19th Century.
