This is a true story of a man who maintained an ageless body by a truly natural diet.

Harumichi Hida (1883-1956) is a founder of Hida-siki spirited body training system (Kyoken-jutsu) in Japan.

Harumichi Hida (1883-1956).

Harumichi is not well known outside Japan, but he is known as an amazing man who acquired superhuman power.

Harumichi was so sickly child that he was told twice by a doctor that he would die young.

Actually, when he was 5 years old, Haruichi was stricken with measles and fell critically ill.

So, he could not enter junior high school until 18 years old.

Furthermore, Harumichi was often dubbed skinny,” because he was emaciated from his childhood.

After he had a narrow escape from death, Harumichi had a serious desire to get a better body.

So, in his eighth year, Harumichi decided to become stronger.

He studied and practiced a huge number of physical health methods and body training systems of all ages and all countries.

As a result of his intensive research and practice, Harumichi developed his own body training method by incorporating Western weight training into the traditional idea of Japanese Hara (Tanden)”.

Various styles of martial arts describe hara as being just below or directly behind the umbilicus.

In Japanese tradition, hara is considered to be the physical center of gravity of the human body and is the seat of ones internal energy (qi, prana).

In the following figure, the point A represents navel, the point B represents the lower back and the point O represents the centre of the body. 

In the Japanese tradition, masters of Japanese calligraphy, swordsmanship, tea ceremony, martial arts, and the other arts, are considered to be acting from the hara.

Harumichis training method is characterized in straining the abdomen and lower back equally to concentrate all power in the centre of the body at an accelerated pace.

Actually, Kyoken-jutsu transformed Harumichi’s body beyond recognition in just two years.

Harumichi retained nothing of the frail and skinny boy that he once was.

He turned into a young man of strong build just like an ancient Greek statue.

Amazingly, Harumichi acquired superhuman strength and power through the training of Kyoken-jutsu.

On the night of June 18, 1923, Harumichi practiced Kyoken-jutsu enthusiastically in a 2-meter-square small hut.

Suddenly, the great power that he had never experienced before spouted from the center of the abdomen and lower back.

Harumichi was surprised by the power that came from the center of his body.

Then, he tried to stomp hard on the floor by his right foot while keeping the body posture.

Amazingly, Harumichi put his right foot through the sturdy floor one inch thick without feeling any resistance.

The part of the sturdy floor one inch thick punched out by Harumichi’s right foot. The shape and the size of the part correspond to those of Harumichi’s right foot.

Furthermore, when he trampled down the floor, Harumichi snapped off even the wooden floor joist, just like he was breaking a twig.

In this way, Harumichi actually became a superman with superhuman strength and power.

As described in the previous post, Harumichi kept as much strength and quickness as compared to when he was young.

Amazingly, even in his seventies, Harumichi’s strength did not decline at all.

Actually, when he was in his 70s, Harumichi had a contest of strength with a young man who was feared by villagers for his Herculean strength.

However, Harumichi easily got the better of the young man.

Also, when his friends saw Harumichi after an interval over ten years, they all looked at him in amazement.

You haven’t changed at all.

Your face, body and everything is the same.

It’s unbelievable!

For these words, Harumichi used to answer as follows:

No, I’m not the same as before.

I’ve changed a lot.

I feel much stronger and greater than I was in my 20s and 30s when I devoted myself to building up my body.

My whole body including the shape, the skin color, and the strength is increasingly becoming better.

So, I’m becoming stronger and stronger!

Therefore, Harumichi was actually an ageless and immortal superman.

To tell the truth, one of the secrets of Harumichi’s ageless body was his own special diet.

Here, I would like to introduce Harumichi’s special diet and his unique philosophy of food.

Dead Foods Make an Unhealthy Body

Harumichi had a unique philosophy of food as follows:

The cells and tissues in human body are constantly broken down and built up by metabolism.

Thus, daily foods are crucial for generating new cells and tissues in our body by metabolism.

If you eat stale foods, the generated cells would be unsound and unhealthy ones.

So, if you wish to maintain your fresh body, you have to eat fresh foods in a daily diet.

According to Harumichi, it is ideal to eat foods raw without being cooked or nearly raw as much as possible.

It is because that there is a crucial difference between live food and dead food.

Live food is capable of germination.

On the other hand, dead food is obtained by crushing live food and then by artificially assembling the crushed food again.

That is, the effect of food on the human body greatly depends on whether it is dead or alive, even though the dead food and the live one have the same quantity and the same nutrition value.

For example, suppose that a scientist analyzed brown rice and then confirmed the kind and the amount of its nutrients.

Then, the scientist mixed the same kind and the same amount of chemical substances as those of the brown rice to produce an artificial food.

Here, Harumichi raised a question.

If you water the above artificial food and make it exposed to the sun, would it begin to sprout?


At the moment when you remove the germ from rice and barley, they are already dead and entirely different things from the live ones.

So, no matter how many dead foods you eat, the generated cells cannot be sound, because the sources of the cells are dead things.

Furthermore, even though you eat complete food including all nutrients necessary for a human body, when you destruct its nutrients by overcooking the food, the result would be the same.

Therefore, it is crucial that you eat any food raw as long as it is fresh.

It is Harumichi’s unique philosophy of food.

Sprouted Brown Rice Is a Complete Diet

Harumichi in his later years made brown rice soft by soaking it in water and ate it raw.

If you soak brown rice in water, it begins to sprout in a few days.

According to Harumichi, sprouted brown rice is a complete diet.

He made a detailed study of brown rice and carried out some experiments using his own body to investigate the right cooking procedure and the adequate amount of brown rice.

Harumichi said,

Sprouted brown rice is a sovereign remedy that is full of life force.

Thus, it preserves your health and keeps your brain sharp.

Also, at one feed, it is enough in nutritive value to eat four or five teaspoons of sprouted brown rice and several pieces of vegetables such as lettuce leaves and wild grasses, and fresh water.

Actually, Harumichi preserved good health even in his 70s with the above amount of food.

On the other hand, he found that animal food products such as milk, eggs and meats clearly slow down the workings of his mind.

Thus, Harumichi concluded,

Animal products could generate a harmful effect on human mind.

Furthermore, Harumichi also insisted that everyone could unleash his or her latent psychic ability by eating raw brown rice and vegetables and by practicing Kyoken-jutsu.

It Is Important to Live in Accordance with the Natural Order

Harumichi called his unique diet “Tenshin Diet.”

In Japanese, “Ten” means,

God, Heaven and Natural

and “shin” means,


So, “Tenshin Diet” means,

Truly Natural Diet

That is, Harumichi’s philosophy of food can be summarized as follows.

Eat in accordance with the natural order

This philosophy is also consistent with kannagara spirit of Japanese Shinto Philosophy, meaning,

Living in accordance with the way (path) of God

The basic concept of kannagara spirit is very simple.

The natural order (God) gave us everything necessary for preserving human body healthy.

Thus, if you eat foods just as provided by the natural order without removing or destructing their nutrients, you will get healthy, but otherwise, you will get sick.

In other words,

If you get healthy, eat foods just as provided by the natural order.

If you get sick, eat foods in a way against the natural order.

It’s a very simple philosophy.

In this way, Harumichi maintained an amazing ageless body by Tenshin Diet.
