Japan had an estimated 4.5 million unemployed － or under-employed － and unmarried 35- to 54-year-olds who still lived at home in 2016. They have been dubbed "parasite singles" by researchers.
Japan’s population is set to plummet from 127 million to 88 million by 2065 - and is projected to drop even further to just 51 million by 2115 if current trends continue.
By then nearly 40 percent of the country will be senior citizens. There will be 1.3 workers for every person over the age of 65. Economists have described the situation as a “demographic time bomb”.
About 20 percent of “parasite singles” rely solely on parents for financial support. When their parents pass away, they could become a burden on the state. “Once they use up inherited assets and savings, when nothing is left, they will go on the dole”.
But many “parasite singles” argue that they did not choose their lifestyle, but were handed it by the economy.
