Japan is the "oldest" country in the world, with an average age of 48yo, while the US is 38yo. A big chunk of their population is already above retirement age, but there aren't enough younger people to fill in their spots. It's gotten to the point that many companies (which used to force retirement around age 60) are now raising it to 65. And while they use to allow those who were retired to "re-apply" for their job at reduced pay, they are now being given bonuses to continue working past retirement age to maintain steady employment numbers. The next generation of Japanese are facing very difficult lives of either 1) higher taxes in a nation with an already high cost of living, or 2) a total and complete inability to retire as they get older.
