In a 2001 research paper on ikigai, co-author Akihiro Hasegawa, a clinical psychologist and associate professor at Toyo Eiwa University, placed the word ikigai as part of everyday Japanese language. It is composed of two words: iki, which means life and gai, whichdescribes value or worth.
According to Hasegawa, the origin of the word ikigai goes back to the Heian period (794 to 1185). “Gai comes from the word kai (“shell” in Japanese) which were deemed highly valuable, and from there ikigai derived as a word that means value in living.”
There are other words that use kai: yarigai or hatarakigai which mean the value of doing and the value of working. Ikigai can be thought of as a comprehensive concept that incorporates such values in life.
There are many books in Japan devoted to ikigai, but one in particular is considered definitive: Ikigai-ni-tsuite (About Ikigai), published in 1966.
The book’s author, psychiatrist Mieko Kamiya, explains that as a word, ikigai is similar to “happiness” but has a subtle difference in its nuance. Ikigai is what allows you to look forward to the future even if you’re miserable right now.
Hasegawa points out that in English, the word life means both lifetime and everyday life. So, ikigai translated as life’s purpose sounds very grand. “But in Japan we have jinsei, which means lifetime and seikatsu, which means everyday life,” he says. The concept of ikigai aligns more to seikatsu and, through his research, Hasegawa discovered that Japanese people believe that the sum of small joys in everyday life results in more fulfilling life as a whole.
A Concept for Longevity?
Japan has some of the longest-living citizens in the world – 87 years for women and 81 for men, according to the country’s Ministry of Health, Labor and Welfare. Could this concept of ikigai contribute to longevity?
Author Dan Buettner believes it does. He's the author of Blue Zones: Lessons on Living Longer from the People Who’ve Lived the Longest, and has travelled the globe exploring long-lived communities around the world, which he calls “blue zones”.
One such zone is Okinawa, a remote island with a remarkably high number of centenarians.
While a unique diet likely has a lot to do with residents’ longevity, Buettner says ikigai also plays a part.
