OUR MISSION
To live long is not enough.
To live long well — that is the point.
The gap between Japanese life expectancy (~84) and healthy life expectancy (~72) is roughly 12 years lived in some form of care or dependency. Our mission is to shrink that gap toward zero — through food, movement, sleep, mind, and learning, grounded in the peer-reviewed evidence and the four wellsprings of Japanese longevity.
FROM THE BOOK
The Healthspan Revolution — at a glance
Why do Japanese people live so long, and live so well? The essence of the book, in four tables.
① The Four Wellsprings — the rivers that feed Japanese longevity
The world’s longest healthspan flows from four traditional wells of wisdom.
| Wellspring | The wisdom | The everyday practice |
