What Does Ikigai Really Mean? | The Four-Circle Diagram Was Born in 2014 — In Japan, Ikigai Can Be Small, and There Can Be Many
If you’ve come across “ikigai” in a book or on social media, you’ve probably seen it with a diagram: four overlapping circles.
What you love. What you’re good at. What the world needs. What you can be paid for. Where all four meet, the diagram says, is your ikigai.
It’s a clear, hopeful picture. But when people in Japan say ikigai in everyday life, what they have in mind is shaped a little differently. Today, let’s gently look at that difference.
What you’ll find in this article
- What kind of word ikigai is (and what the “gai” really means)
- Where the four-circle diagram came from — and how
- Why ikigai in Japan can be small, plural, and ordinary
- What we know, and don’t know, about ikigai and living longer
- A few ways to touch ikigai today
Ikigai = “iki” (living) + “kai” (worth it)
The Japanese dictionary Digital Daijisen defines ikigai as “something worth living for; the sense of purpose and joy in going on living.”
The “gai” at the end is the word kai (甲斐). The dictionary describes it as the visible result of an action, the effect of one’s effort, the worth one can hope for — as in yatta kai ga atta, “it was worth doing.”
Attached to a verb, kai makes a whole family of everyday words:
- hataraki-gai — the reward of working
- yari-gai — the satisfaction of doing something
- oshie-gai — the joy of teaching someone who grows
In the same line, iki-gai is the felt worth of being alive. Less a grand goal, more the small sense that today was worth living.
The four circles came from a 2014 blog post
So where did the four-circle diagram come from?
Not from Japan. In May 2014, a blogger named Marc Winn wrote a post called “What’s your ikigai?” He had learned the word from a talk on longevity — Dan Buettner’s TED Talk.
The diagram Winn used was originally a four-circle chart about “Purpose,” said to have been made around 2011 by Andrés Zuzunaga in Spain. Winn swapped the word in the middle for “ikigai.”
The post spread around the world, and the image has been copied countless times since. In a later post in 2017, Winn himself looked back on it:
“The sum total of my effort was that I changed one word on a diagram and shared a ‘new’ meme with the world.”
The diagram isn’t bad. As a tool for thinking about work and careers, it’s genuinely useful. It’s simply a diagram about purpose — not something that grew out of the Japanese word ikigai.
In Japan, ikigai can be small — and there can be many
Ask someone in Japan “What’s your ikigai?” and you might hear:
- Watching my grandchildren grow up
- The first cup of coffee in the morning
- Growing vegetables in my garden on weekends
- Going to see my favorite idol live
None of these need to earn money. You don’t have to be good at them. Whether the world needs them hardly matters. Nothing says all four circles have to line up.
Neuroscientist Ken Mogi, who has written books on ikigai in English, has said in an interview that the four-circle diagram is “too narrow of a definition for ikigai.” The one thing truly needed, he suggests, is that you love it — even singing karaoke badly can be ikigai, if you love it.
The person who thought hardest about ikigai: Mieko Kamiya
In Japan, one book often named when people talk seriously about ikigai is Ikigai ni tsuite (“On Ikigai,” Misuzu Shobo, 1966) by psychiatrist Mieko Kamiya (1914–1979).
Kamiya spent many years treating patients at Nagashima Aiseien, a Hansen’s disease sanatorium on an island in the Seto Inland Sea. Alongside people from whom illness had taken so much, she kept asking what it is that lets a person go on living, and gathered those thoughts into this book.
According to Japanese studies of her work, Kamiya described the joy of feeling ikigai as something like a joy that comes before reasoning. She also contrasted it with happiness: the sense of ikigai, she wrote, leans toward the future more than happiness does.
Not only whether today feels full — but whether there’s something you want to do again tomorrow. It fits neatly with where we began: kai, the felt worth of what you’ve done.
Ikigai and long life — what we know, and what we don’t
Ikigai is often talked about alongside longevity, and Japan does have research on it.
In 1994, a team at Tohoku University asked about 43,000 people aged 40 to 79 in the Ohsaki area of Miyagi Prefecture a simple question — “Do you have ikigai in your life?” — and followed them for seven years. Those who answered “no” had about 1.5 times the risk of dying compared with those who said “yes,” after adjusting for age, health, and other factors. The study was published in 2008.
But this doesn’t prove that having ikigai makes you live longer. It’s an observed association. It could also run the other way: people in good health may simply find it easier to feel ikigai. The most honest takeaway might be this: ikigai isn’t a tool for living longer.
Touching ikigai, gently, today
One: look for the little “kai.” A dish that was worth cooking. A train that was worth waiting for. Small moments of “worth it” are everywhere once you start noticing.
Two: write down one thing you’d like to do again tomorrow. It doesn’t have to be a dream. “Go back to that bakery” is plenty. Kamiya’s future-leaning feeling probably starts at about that size.
Three: let the answer be more than one. You don’t need to find a single right answer in the middle of four circles. You can have several ikigai, and they can change with the seasons.
In closing
The four-circle diagram invites you to find your one true ikigai. The Japanese word is humbler than that.
Whatever lets you feel that being alive is worth it. And there can be many of those, scattered through your ordinary days.
Like ichigo ichie, treasuring each once-only meeting, or mono no aware, being moved by things that pass, ikigai may be something you notice in everyday life rather than something you go out to find.
Tonight, before you sleep, think of one small thing you’re looking forward to tomorrow. That’s your ikigai for today.

The Ohsaki Study is observational and does not show that ikigai causes longer life.
