To cope with its aging population, Japan did lots of things, first it upped retirement to age 70.
Second (as well as increasing robot use) they introduced mandatory private health insurance for all to pay for care for those over 65 (!) , including nursing homes, home care, and meals.
Thirdly, they greatly upped immigration (granting full residency for families as well). This is to fill critical gaps in manufacturing (industrial products), building, food and drink as well as nursing. Also taxi, bus, and truck drivers, railway and forestry.
This is a major shift from Japan’s historically restrictive policies as they now need their foreign workforce drawing from Southeast Asia including Vietnam, China, Philippines, Myanmar, Indonesia and Sri Lanka.
