Amid concerns over rapid depopulation, a private panel has proposed that Japan should aim to have a stable population of 80 million by 2100 in order to maintain economic growth.

Last April, the government released an estimate that the population would be reduced by half to about 63 million in 2100, with 40% of people expected to be 65 or older.

Japan has wrestled with the issue of a declining birthrate for decades, but the situation is about to “change drastically,” with the country now entering a serious phase of population decline, the panel, headed by Nippon Steel honorary chairman Akio Mimura and consisting of 28 members including prominent academics and business leaders, said Tuesday.
