For the first time ever, more than one in 10 people in Japan are now aged 80 or older.
National data also shows 29.1% of the 125 million population is aged 65 or older while Japan has one of the lowest birth-rates in the world. In Ireland, around 13pc of the population is over 65.
The country’s elderly employment rate is among the highest across major economies – workers aged 65 or more make up more than 13% of the national workforce.
The country was estimated to have had fewer than 800,000 babies born last year – the lowest number since records began in the 19th century.
In the 1970s, that figure was more than two million.
Prime Minister Fumio Kishida said in January that his country is on the brink of not being able to function as a society because of its declining birth rate.
