What lies ahead for many other countries, including the United States, is in rural areas and regional cities outside greater Tokyo: lots of people aging and dying, and relatively few giving birth and raising kids. In today's Japan, the young and middle-aged are consumed by caring for the old, and small-town resources are overstretched. Japanese innovators are already demonstrating what's possible and, in many cases, not with high-tech fixes but by showcasing design thinking, dignity and respect.

[Japanese innovators have] yielded ideas that prioritize helping old people flourish, not just managing their illnesses, disabilities and deaths.
