Well, do you know which prefecture in Japan has the longest life expectancy? Knowing the secret of longevity may provide clues to improve our health and quality of life. In this article, we will explore in detail which prefecture has the longest life expectancy in Japan and why.

Which prefecture in Japan has the longest life expectancy?

The prefecture with the longest life expectancy in Japan is Okinawa Prefecture . Okinawa has long been known as the "island of longevity," boasting one of the highest average life expectancies in the country. However, in recent years, Okinawa has been losing its longevity to other prefectures, but it still attracts a lot of attention as a prefecture with a long life expectancy.

The reason for Okinawa's longevity

1. Healthy diet

Okinawan cuisine is known to be low in calories and well-balanced nutritionally, but what specific ingredients contribute to its longevity?

Tofu and soy products

The Okinawan diet includes many soy products such as tofu and miso, which are rich in protein, vitamins, minerals, and isoflavones, and are said to help prevent heart disease and cancer.

Bitter melon

Bitter melon is a typical ingredient in Okinawan cuisine and is often eaten as "goya chanpuru". Bitter melon is rich in vitamin C, has antioxidant properties, and is effective in boosting the immune system. It is also said to be useful in controlling blood sugar levels.


Seaweed such as kelp and mozuku is rich in dietary fiber and minerals, especially iodine, which plays an important role in normalizing thyroid function and promoting metabolism.


Okinawans also eat a lot of seafood. Blue fish, in particular, is rich in omega-3 fatty acids, which help maintain cardiovascular health. DHA and EPA also help maintain brain function and are effective in preventing dementia.


Okinawa also eats many unique vegetables known as island vegetables. For example, island scallions and island carrots are rich in vitamins and minerals and are said to have strong antioxidant properties.


In Okinawa, dishes and teas using turmeric are popular. Turmeric contains a compound called curcumin , which has anti-inflammatory and antioxidant properties and helps improve liver function.

Turmeric is also good for the brain.

What about health other than food?

2. Mild climate and environment

Okinawa's warm climate and beautiful natural environment are important factors for reducing stress and living a relaxed life. The environment surrounded by the sea and mountains is ideal for refreshing the mind and body , and a lifestyle in harmony with nature contributes to longevity. An environment rich in negative ions? Negative ions also purify the blood.

3. Social Connections

Okinawa has a strong community bond known as "village society," and people place great importance on connections with family and local people. There is no sense of loneliness, and the spirit of helping and supporting each other is deeply rooted, making it an environment where mental health is easily maintained.

This type of environment is gradually disappearing, not only in Japan but also throughout Asia.

4. Traditional health practices

Okinawa has many healthy habits that have been passed down since ancient times. For example, they naturally incorporate exercise into their daily lives, such as waking up early in the morning for a walk or dancing the traditional physical dance "Eisa." These habits lead to a long and healthy life. Moderate exercise and music are probably one of the secrets to good health! Modern people are highly dependent on smartphones and computers. Why not try to get away from the internet for a few hours a day?

Meanwhile, what is the average life expectancy and situation in Asian countries?
