More than 40% of the population is expected to be over the age of 65 in 2060. īased on 2012 data from the National Institute of Population and Social Security Research, Japan's population will keep declining by about one million people every year in the coming decades, which would leave it with a population of around 70 million by 2060 and 42 million by early 22nd century if the current projections do not change.
