In The Blue Zones: The Secret of Living Beyond 100 Years, Dan Buettner explores the lifestyles and habits of people in regions where exceptional longevity is common. These areas, known as Blue Zones, have the highest concentration of centenarians—people who live to 100 years or more.
The third Blue Zone we will explore is Okinawa.
Okinawa (Japan)
Ikigai, the best-selling book, is inspired by a study of the people of Okinawa, Japan.
Okinawa, one of the southernmost islands of Japan, has the highest proportion of centenarians in the world. These long-lived individuals regularly sit down on and rise from the floor multiple times a day, an activity that strengthens their legs, back, and core while improving posture, flexibility, strength, and mobility.
One key habit contributing to their health is eating until they are 80% full. This mindful eating practice helps prevent overeating, supports better digestion, and reduces the risk of obesity—promoting overall well-being.
The Okinawan diet is also rich in soy-based foods, such as tofu and miso soup. Tofu contains flavonoids that may help protect heart health and reduce the risk of breast cancer. Another staple of their diet is the purple sweet potato, which is packed with nutrients and antioxidants.

Okinawans also benefit from a strong social support system called a moai—a lifelong circle of friends who support one another emotionally and socially throughout life. Additionally, they possess a deep sense of purpose, known in Japanese as ikigai, which provides meaning and direction in their lives.
These are some other habits identified that has benefitted the community with longevity making them one of the Blue Zones in the world.
Okinawa is the third region and coming week we will go through the next of five regions and their main pillars of a long life exploring and reflecting on their secrets and what we can learn.
Watch this space it might be the most important lesson in all of our lives…
