About The Ikigai Diet

The Ikigai Diet, the diet eaten by Japan’s centenarians and young naturalists, is a high fibre, largely plant-based diet, rich in what the West would consider superfoods.

When we think of Japanese centenarians, the residents of Okinawa come to mind thanks to books like The Okinawa Way and, more recently Ikigai: The Japanese Secret to a Long and Happy Life. It was back in the 1980s when Okinawa was regarded as an island of longevity. The truth is Okinawa is not the only prefecture to have a high concentration of centenarians in Japan.

There are many healthy centenarians living in all prefectures of Japan. More recently prefectures such as Nagano and Shiga, have held the highest concentration of centenarians. 

It’s Not a Blue Zone. It’s A Lifestyle

Contrary to popular belief, there is no one “Blue Zone” in Japan but rather a unique diet and lifestyle practised in the rural areas of most of Japanese prefectures that results in the local residents living into old age with healthy bodies, sound minds and happy hearts

This lifestyle is known as Satoyama Living.

Satoyama Living

Like much of Japan’s traditional culture Satoyama living is an ancestral lifestyle that has lost its significance in the modern age. Fortunately, though, there are groups of Japanese who have returned to this way of living. These people are called Shizenha, young naturalists who have moved to rural areas of Japan, choosing to lead a more sustainable way of living. 

They have adopted a Satoyama lifestyle like the Japanese of old; growing their own rice and vegetables through organic farming, making fermented foods at home, bringing up children surrounded by nature and recovering the traditional Japanese diet. Not only have they inherited the natural culture; they have also upgraded it to a way applicable to the modern age.

The Ikigai Diet

The ikigai diet offers you the opportunity to embrace a healthy diet inspired by the wisdom of Japan’s centenarians and the knowhow of the Shizenha, Japan’s emerging naturalists. 

Through our podcast, blog and courses we aspire to help you live a long and healthy life.

My name is Sachiaki Takamiya. I am a writer and the founder of the Ikigai Diet. As a writer, I have written many books. My best-known work is a spiritual adventure novel called Tenjo-no-Symphony which was published in Japanese from Kodansha in 2006. In English, I have written books called Zen and a Way of Sustainable Prosperity, IKIGAI BUSINESS, and The Ikigai Diet.

I live in a small rural town called Hino Town in Shiga Prefecture Japan, where I lead a sustainable lifestyle; I grow vegetables using organic farming and natural farming, make fermented foods such as miso and natto. I also have a network of naturalist friends in Hino Town, surrounding areas in Shiga Prefecture, and all over Japan.

I have had a love affair with Japan and Japanese food ever since I first visited the country at the age of five. Some 40 years later my relationship with Japanese food has never been more intimate. The older I get the more I seem to discover how unique, delicious and healthy the foods of Japan are.
