Ikigai: A Japanese concept to improve work and life

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.

But, knowing your ikigai alone is not enough. Simply put, you need an outlet. Ikigai is "purpose in action," he says.

For 92-year-old Tomi Menaka, her ikigai is to dance and sing with her peers in the KBG84 dance troupe, she told the Mainichi newspaper . For others, it might be work itself.

In a culture where the value of the team supercedes the individual, Japanese workers are driven by being useful to others, being thanked, and being esteemed by their colleagues, says Toshimitsu Sowa, CEO of HR consulting firm Jinzai Kenkyusho.
