We at Okinawa Sango Co., Ltd. have been blessed with many opportunities in the past 34 years since our establishment, including meeting many Okinawan farmers who are full of passion.

Among them, the pure thoughts of Mr. and Mrs. Shimabukuro at Mana Mango Farm in Nago City touched my heart. One day, while browsing among the internet, a book entitled Nel contagio (translated as The Age of Coronavirus in Japanese) written by an Italian author Paolo Giordano came into my view. When I finished reading it, I was overwhelmed. From a scientific view, the book dug deeply into the infection of new coronavirus, and asked us the important questions “What should we keep, what should we give up, and how should we live?”

“What a wonderful thinker,” I thought… and I asked myself the same questions: “What should we keep, what should we give up, and how should we live?”
And they kept me thinking.

The next day, Mr. and Mrs. Shimabukuro at Mana Mango Farm sent me some beautiful mangoes that I have never seen before.
As I kept wondering what I could do, at that moment the thought came to me,
“This is it!”
“This is what Okinawa Sango should do!”
“We can do this!”

Mr. and Mrs. Shimabukuro at Mana Mango Farm have decided to grow mangoes in Okinawa without using pesticides and chemical fertilizers, and they have been working so hard for years. Their belief and determination are very noble.

In his book, Paolo Giordano wrote that, “If we don’t change, the same situation caused by the coronavirus this time will happen again.”
The book further illustrates that “The cause of this pandemic lies in the dangerous way we humans treat nature and environment, destruction of forests, and our thoughtless act of consumption.”
“This suffering makes us realize the truth, which is usually blurred and invisible to us, and make us reconsider our priorities.”

There have been suggestions similar to Paolo Giordano’s, and I hope that in response, more experts would rise up to mee the challenges.

Let us return to issues in Okinawa. In a humid subtropical climate as Okinawa, the difficulties are beyond imagination to grow crops without using pesticides or chemical fertilizers.
Nevertheless, Mr. and Mrs. Shimabukuro rose up to meet the difficult challenge, showing us the power of a pure heart and the right way to live as human beings. The wonderful mangoes they delivered to me are the best illustration of that.
Following the example of Mr. and Mrs. Shimabukuro, it appears to me that it is time for us to “take a good look at the reality, and take actions”.

For days on the news, we learnt that cliffs are collapsing and rivers are overflowing.
To me, these are urgent messages from our mother nature.

What should we keep, what should we give up, and how should we live?
In response to these questions raised by Giordano, I would like to start with what I can do.

Nature is alive in fertile soils.
There exists the skillful decomposition and purification by trillions of microorganisms living in the soil, the purification by the soil and river water, and the circulation of substances by living things that has constantly protected the earth.
We might have made a huge mistake.
I would like to pay my heartfelt respects to those who changed their farming method to the one allowing many little creatures to live.
The little creatures are diligent workers.

Mangoes from Mana Mango Farm emit a rich aroma that fills my house.
Below are two illustrations showing the differences between what is happening now, and the vision depicted by Mr. and Mrs. Shimabukuro who grew those amazing mangoes.

Switching to their farming method will lead us from pursuing material civilization to a sustainable and happy society.

The World Health Organization: WHO has published (Nutrition advice for adults during the COVID-19 outbreak) outlining nutritional guidance for new coronavirus infections.

At the beginning of the journal, it states that nutrition and water intake is a source of life, and that a balanced diet boosts immunity and provide a healthy state, thus lowering the risk of getting diseases such as infections.

WHO(World Health Organization)
If you look at the top foods recommended by the WHO, they were common in our homes about 60 years ago. Green vegetables and seafood were on the table every day.

In the olden days in Japan, grandmothers and mothers used to stand at the kamado(cooking stove). And they were preparing a side dishes to please their family. They were also making delicious miso with boiled beans.

In summer, an eggplant and a cucumber are colorfully attached to the dining table after pickled with bran bed, and appetite is stimulated. In the winter, they are all pickled by grandmothers, such as Takuwan(pickled radish), Chinese cabbage and nozawana(brassica).

Fermented foods were a normal part of it. There are no colorants, preservatives or synthetic seasonings. Vegetables are dried in the sun and are packed with vitamin D and fiber, so they are full of nutrition.

They were making them for their families. It was filled with mother’s love. Home cooking seems to be the best way to stay healthy. Such a Japanese dining table is important in this day and age, isn’t it? A mother who cares for her family will heal her family. I think that the feeling of “Thank you” and “Thank you” for the gratitude to the creator of the food, “Itadakimasu” and “Thank you” for the “edible life” must have fostered a sense of reverence for nature in our childhood.

Both green vegetables and fermented foods boost our body’s metabolism. In this WHO’s advice, It is recommended that you avoid processed foods that are high in fat and salt, eat fresh foods, cook low in fat, salt and sugar, and drink plenty of water every day.

About water

Water is indispensable for sustaining life, and it is the root of life as it is involved in transporting nutrients and various components in the blood, excreting wastes, and regulating body temperature.
Okinawa Sango Co., Ltd. believes that hot water (Sayu), which is slightly higher than the body’s temperature, is recommended to replenish the water that the body needs. Coral Calcium users have been drinking hot water and are doing very well.

How to make SAYU (hot water)

Activation of microorganisms in soil is important to grow delicious crops.
Calcium and magnesium alone do not make crops delicious.
Other trace minerals are required. (Mr. Fukasawa, an experienced farmer specialized in fruits farming in Yamanashi, Japan)


Agriculture resistant to climate change is essential.




Crops grow healthy when microorganisms in soil work properly.

・There is a soil where variety of life lives around roots of trees.
・Soaked rain water will be filtered through this heavy covering of leaf mold and become clean groundwater.
・Healthy soil create fine water.


Our small step will cure our farm and by cleansing river and sea water, bring back diversity of organisms.


Bring back beauty of coral reefs.


Let’s start SDG’s from everyday life.
Let’s bring beautiful coral reefs back to Okinawa once again.

We can reduce countless wastes in our natures discharging from our daily life by taking in naturally grown coral powder made from weathered reef coral that has been died instead of using artificial materials made with petrochemistry.

Coral powder made from dried weathered reef coral is composed mainly of calcium carbonate.

As you see the graph below, used coral powder in various fields will be reused for the ground and disassembled in the network of microbes naturally.

Raw material of coral powder will never be wasted. It’s the pure natural material grown in the sea of Okinawa.

As our first step to take, we will commit to support agricultures to reduce inflow of red clay to our coral reefs from farms here in Okinawa, in 2020.


We incorporate natural material “weathered reef coral grains” into various scenes of our lives to make a healthy life.
