In our quest for health, we often focus on the essentials: what we eat, how much we exercise, and how well we sleep. These are all vital, but so too are our intangible needs for meaningful relationships and purpose.
People on the Japanese island of Okinawa are some of the healthiest and longest-living people on the planet. Moai is one of the reasons that the people on the Japanese island of Okinawa live so long and so well.
A moai is a group of lifelong friends who support each other socially, financially, emotionally, and spiritually. This somewhat formalized relationship is established during childhood and is meant to endure throughout one’s lifetime.
Moai meet regularly—monthly, weekly, or even daily—to chat, reminisce, share advice, and support each other through whatever may be happening in their lives. Many Japanese belong to more than one moai.
The word moai means to “meet for a common purpose.”
Okinawans and the Secrets of Longevity
Researchers have been trying to determine what makes Okinawa and its residents so extraordinary for decades. According to a BBC article, for every 100,000 inhabitants, Okinawa has 68 centenarians—more than three times the numbers found in U.S. populations of the same size. Even by Japanese standards, Okinawans are remarkable, with a 40 percent greater chance of living to 100 than other Japanese people.“At 80, you are merely a youth; at 90, if the ancestors invite you into heaven, ask them to wait until you are 100. ... and then you might consider it.”So, what can we learn from Okinawans? Craig Willcox, a professor of public health and gerontology at Okinawa International University, says it comes down to three factors: diet, social practices, and genetics. Mr. Willcox is also a co-principal investigator for the Okinawa Centenarian Study, which has been investigating Okinawan longevity since 1975.

“About two-thirds of longevity is related to diet and way of life; the rest is genetics. Generally speaking, you need the genetic rocket booster if you want to get into the 100s, not just a good diet,” Mr. Willcox said. “We haven’t looked into whether or not Okinawa has a genetic advantage over other parts of Japan, but longevity does run in families here.”
Then there’s the way that social support is built into Okinawan society through moai. This social mechanism brings groups of people with shared interests together, allowing them to develop strong emotional bonds that last a lifetime. Mr. Buettner said that’s a crucial element to living a long life, noting that “loneliness is as bad for you as smoking.”
Mr. Willcox said that belonging to multiple moai is common.
The History of Moai
Moai have a long history in Japan, originating hundreds of years ago as a way for villages to create their own financial support system. Moai were originally formed to pool the resources of an entire village for different projects or public works. If someone in the village needed money to buy land, pay medical bills, or deal with an emergency, the money was raised locally to help members of the community.The Science of Social Connections
Scientific studies have also demonstrated the impact that social connections have on our health and well-being.
Final Thoughts
Research has shown that the quantity and quality of our social relationships impact our health and well-being. Those with close connections to others generally experience less stress, are happier, and live longer. Conversely, older people who don’t have close friendships are more likely to develop chronic diseases, such as heart disease, diabetes, and depression, and are at higher risk of stroke.So, although eating well, limiting stress, and getting good-quality sleep are important factors for a healthy life, so too is talking to your neighbor and making time regularly to meet with friends. Of course, social ties aren’t just a matter of health, they also make our time here a little more enjoyable—and spread that joy to others.
