Japan's parliament passed a law Friday that clears the way for its ageing Emperor Akihito to step down, in what would be the first imperial abdication in more than two centuries.
The popular 83-year-old monarch shocked the country last summer when he signalled his desire to take a back seat after nearly three decades on the Chrysanthemum Throne, citing his age and health problems.
The unexpected move presented a challenge since there was no law to deal with an emperor retiring from what is usually a job for life.
The one-off rule was passed in the last-stage upper house on Friday in a unanimous decision after the lower chamber gave its stamp of approval last week.
The abdication must take place within three years of the new law taking effect or it expires -- and it only applies to Akihito.
Japanese media have said the government is eyeing the end of 2018 as a likely timeline for Akihito's abdication.
The status of the emperor is sensitive in Japan given its 20th century history of war waged in the name of Akihito's father Hirohito, who died in 1989.
Some scholars and politicians worried that changing the law to allow any emperor to abdicate could put Japan's future monarchs at risk of being subject to political manipulation.
Akihito, who has been treated for prostate cancer and had heart surgery, is expected to step aside in favour of his eldest son, Crown Prince Naruhito.
There have been abdications in Japan's long imperial history, but the last one was more than 200 years ago, so politicians had to craft new legislation to make it possible.
