In the Okinawan language, Blue Zones Expert & bestselling author fellow Dan Buettner says there is no real term for what most of the world calls retirement. He frames the gap as cultural rather than linguistic. Buettner puts it this way: “In the Okinawan language, there’s not even a word for retirement. Instead, there’s one word that infuse your entire life, and that word is ikigai.”
A note before going further. We are writers and editors who read research carefully, not clinicians, psychologists, or epidemiologists. What follows is reflection on a body of work, not health advice. Most of the studies here are observational, and population-level patterns do not translate cleanly into predictions about any one reader’s life.
Ikigai is a common Japanese word, and its translation is approximate rather than precise. Buettner describes the Okinawan relationship to it as “this vocabulary for purpose in the word ikigai, which roughly means the reason for which I wake up in the morning.” The hedge in “roughly means” is worth keeping. Okinawan and Japanese lexicography is contested, and the tidy English rendering of ikigai as a single life purpose is largely an interpretation that travelled west with the blue-zone story.
Buettner’s blue-zone work, a collaboration between National Geographic and the National Institute on Aging, identified a handful of regions with unusually high concentrations of centenarians. Okinawa was one of them. The idea that has stuck, beyond the diet and the daily walking, was that older Okinawans kept a reason to be useful well past the age most cultures hand someone a gold watch and a quiet afternoon.
Whether the language truly lacks the word matters less than what the observation gestures at. A life organised around still being needed looks different from one organised around an exit date.
The Japan Collaborative Cohort Study tracked 29,517 men and 41,984 women for a median of 19.1 years and recorded 4,680 cardiovascular deaths. As stated in the paper, “Greater Ikigai was associated with a lower risk of CVD mortality”, an effect that appeared stronger in men and, interestingly, was confined to people who were not employed. The pattern suggests purpose may matter most precisely when a job is no longer supplying it.
A 2022 longitudinal study found that having Ikigai was associated with decreased depressive symptoms, and higher life satisfaction and a 36% lower likelihood of developing dementia.
These are correlational studies. Purpose, health, and the timing of retirement are tangled together, and a person already in poor health may simply find it harder to feel a reason to get up. The link is real enough to take seriously and loose enough that no single study deserves the last word.
Part of what makes the association plausible is that researchers have found bodily traces of it. One study of 985 adults found that greater life purpose predicted lower allostatic load, the cumulative wear-and-tear the body accumulates from chronic stress, a full ten years later.
A smaller experiment offers a possible mechanism: among older adults put through a standard laboratory stress test, those higher in purpose did not start with lower stress hormones but recovered to their resting levels faster after the stressor passed. That last finding comes from just 44 people in a lab, so it reads best as a clue to chase rather than a settled mechanism.
The thread running through this work is that a sense of mattering may not stay in the mind. It appears to leave a faint signature in how the body handles stress over years. Buettner makes a sharper version of the claim. He told one interviewer that “if you retire without a sense of purpose, there’s an enormous spike in mortality,” adding that “the second most dangerous year in your life is the year you retire on a population level.” It is a memorable line but Buettner’s framing of an epidemiological association rather than a measured law. The confounding between health, purpose, and the decision to stop working sits right underneath it.
There is a complication the blue-zone story tends to soften. Okinawa’s longevity advantage has been slipping for decades. By 2020, Okinawan men had fallen to 43rd of Japan’s 47 prefectures, down from first place in 1985, while Okinawan women slipped to 16th. The physician Andrew Weil offers one common reading. He has noted that Okinawan longevity has fallen sharply in recent years, a decline he attributes mainly to a greatly increased consumption of American-style fast food.
Weil himself hedges, and that caution is right. The decline is almost certainly multifactorial, tied up with changing diets, less daily movement, and generational shifts. If purpose were doing all the work as some popular telling implies, a culture that supposedly never invented retirement should not be losing ground so quickly. Something larger than mindset is moving the numbers.
If the question of purpose lands somewhere tender, especially around a coming retirement or a hard transition, a qualified counsellor or therapist is a good person to talk it through with.
