A Lecture On
Water That Prevents & Cures Disease
(Translated From Japanese)
Director, Water Institute
PREFACE : Two Kinds of Water
concluded that there are two kinds of water: water that
produces disease and water that prevents and cures
disease. I must also make the following almost
unbelievable point. From the dawn of the human race up
to the present day, I think human beings have been
acquainted with water that produces disease.
because 99.99 percent of the water that actually exist
on the earth is or was, in fact, nothing but this type
of water. Thus, up until now, the human race has had to
depend on "water that produces disease." As a result,
since the birth of humankind, human beings have suffered
Conversely, we may look at this situation in the
following way. What will happen, if up until now, we had
depended on the other type of water, the "water that
prevents and cures disease?" Since 1985, I have been
searching for the water that prevents and cures disease.
During that time there were many detours, but I believe
that very recently I have finally discovered what this
is. In a nutshell, it is water that contains a large
amount of hydrogen gas, which I have termed
Why can I
detailed explanation will be provided in this guidebook,
but in short, Hydrogen Rich Water gets rid of active
oxygen, which is considered to be the cause of all kinds
of diseases. And that is not all. The water I am
proposing has another big advantage: anyone can produce
Hydrogen Rich Water easily, reliably and cheaply. I
would like you, too, to check out delicious taste and
wonderful qualities of Hydrogen Rich Water, "the water
that prevents and cures disease."
ONE : The Genesis of Water
birth of the earth is supposed to have come about by
means of a "big bang" that occurred between 10 and 20
billion years ago. It is also believed that the first
living organisms came out into existence in the water of
this planet some four billion years ago. In other words,
if water had not been present on the earth some four
billion years ago, living organisms would not have
emerged and survived on the earth. Therefore the
presence of water on the earth was the great
prerequisite for the genesis and survival of all living
knows that water is a compound of hydrogen and oxygen.
The bonding of hydrogen and oxygen in a 2 to 1 ratio
produces water, which is expressed with the chemical
formula H2O. The fact that water is a
compound of hydrogen and oxygen signifies that hydrogen
and oxygen attract one another. In other words, if
hydrogen and oxygen did not have this attraction, water
would never have come into existence. Moreover, without
the genesis of water, living organisms would not have
come into existence either. There is an energy that
works to draw these atoms to each other (covalent bond
energy), and it is thanks to this energy that water was
able to come into existence.
water is what is generated by means of this covalent
bond energy, the hydrogen in the water can not exist
alone and independently in a form that is separate from
the oxygen. Not only that, when water is infused with
hydrogen gas taken from something like a compressed gas
cylinder, or when hydrogen gas is generated by
electrolysis to produce water with increased hydrogen
(electrolyzed cathodic water), the hydrogen simply
escapes into the air immediately because it is the
lightest gas in the universe. This is why, as we learned
in high school chemistry, there is hardly any hydrogen
the water we are familiar with is all water that
contains hardly any Hydrogen gas. In short, the water
that exists in nature, the tap water produced by
processing it, bottled water and so forth all have one
big common characteristic: they are all "water that
contains hardly any hydrogen."
Recognizing and understanding this fact from the
beginning is of the utmost importance for the
actualization of your good health and longevity.
TWO : The Genesis of Living Organisms
mentioned in the previous chapter, living organisms
first came into existence in water some four billion
years ago. This tells us that the necessary condition
for the genesis and survival of living organisms must
lie in water. In other words, if this condition were not
found in water, living organisms would not have been
able to come into existence and survive in water. In
other words, we must conclude that the key to the
genesis and survival of them or good health and
longevity of living organisms is undoubtedly to be found
reality, what is the conventional wisdom concerning this
topic? It would probably be, "The key to good health and
longevity couldn't be found in water!..." All I can say,
however, is that this sort of thinking is in fact sheer
nonsense. It is nothing but an irrational opinion that
ignores the truth about the health and longevity of
view, we cannot help but conclude that the key to the
genesis and survival of living organisms, namely our own
health and longevity, is to be found in water. No other
way of thinking could explain the fact that the genesis
and survival of living organisms in water has been
repeating itself for some four billion years on a
it back a step, this is not even a question of health
and illness, because if water had not existed on the
earth, and the key to health and longevity were not to
be found in water, all living organisms would not have
come into being to start with. Therefore, what we have
to think about now are the following questions, which
are the only relevant issues.
What kind of water would be water that maintains
good health and cures disease?
And conversely, what kind of water would be water
that is detrimental to health and produces disease?
are questions that are most important for us to
consider, rather than repeating the generally held
conventional wisdom "The key to good health and
longevity couldn't be found in water".
THREE : Water That Produces Disease
mentioned in the preface, I have concluded that water
can be divided into two kinds: water that produces
disease and water that prevents and cures disease.
First, I shall explain about water that produces
that produces disease" refers to the water we drink
everyday without much thought. This includes tap water,
well water, rain water, water from lakes and mountain
streams, underground water and spring water. In short,
it is the water we usually call natural water or spring
water. Even tap water is really natural water if you
consider where it comes from. It is simply natural water
that has undergone processing at a water purification
plant, where it is infused with chlorine or ozone gas to
various kinds of bottled water sold in convenience
stores and supermarkets, such as natural water, spring
water, mineral water, famous waters from various regions
all over Japan, famous name-brand water and so forth
also fall into the same category. In other words, 99.9
percent of the water we drink on a daily basis is in
fact nothing more than this water that produces disease.
Why am I
able to make this statement? And what on earth are the
characteristics of " water that produces disease ?"
simply, the most important characteristic is the fact
that such water hardly contains any hydrogen; in the
water found in nature, there is almost no hydrogen gas.
The reason for this, as mentioned earlier, is that
although water is composed of two hydrogens and one
oxygen, the action of covalent energy operating between
the hydrogen and oxygen makes it extremely difficult for
hydrogen to exist on its own in a form that is separate
from oxygen and independent of the oxygen. Furthermore,
water containing abundant hydrogen does not exist in
nature because even water that starts out containing
abundant hydrogen loses it immediately. This means that
up to 99.9 percent of the water in nature is nothing but
" hydrogen poor water."
This hydrogen poor water is none other than the
"water that produces disease."
The reason is that hydrogen (active hydrogen) is
necessary to getting rid of active oxygen, which is the
cause of all kinds of diseases, and hydrogen poor water
is water that is deprived of this crucial hydrogen that
is essential for removing active oxygen. In other words,
it is extremely ineffective in getting rid of active
oxygen, and it follows that hydrogen poor water is none
other than water that produces disease.
FOUR : Water That Cures Disease
We have seen that water that produces disease refers to
hydrogen poor water. On the other hand, water that
prevents and cures disease refers to water that contains
a lot of hydrogen, namely, Hydrogen Enriched Water. (
Please note that hydrogen poor and hydrogen enriched
water are terms I have coined.) The basis for this, in
brief, is that the abundant hydrogen found in Hydrogen
Enriched Water becomes active hydrogen in the body and
removes the active oxygen that is considered to be the
cause of all kinds of diseases.
In recent times practically everyone has seen or heard,
on television, radio, newspapers and health magazines,
the expression "active oxygen is the cause of all kinds
of diseases." Active oxygen is exactly what the words
that is active.
The action of oxygen is oxidation, which means that it
burns things up or produces rust on metals such as iron
and copper. Active oxygen thus means oxygen with a
particularly strong oxidizing action. Expressed
metaphorically, if we compare the oxygen we normally
breathe to kerosene, active oxygen would correspond to
gasoline. A simple explanation of the expression "active
oxygen is the cause of all kinds of diseases" is that
because active oxygen has a particularly strong
oxidizing action (oxidative damage) on genes (DNA), it
damages the genes and causes diseases.
Life is maintained in our body by the metabolism in
which the oxygen we breathe in through our lungs burns
up the food we take in through our mouths, and the
byproduct of this process is active oxygen, which is
emitted as a kind of combustion gas.
Let us describe this reaction, in which the air we take
in through our lungs "oxidizes" our food, from the
viewpoint of the food. What happens is that the food
"reduces" the oxygen. The ordinary oxygen that is
reduced by the food becomes active oxygen. We maintain
our lives by breathing oxygen; however, since it is
believed that around two percent of the oxygen we
breathe in is transformed into active oxygen, we cannot
avoid producing active oxygen as long as we are alive.
Therefore to preserve our health it is necessary to
suppress the active oxygen that we are constantly
producing and the trump card in doing this is hydrogen
FIVE : What Is Active Oxygen
Active oxygen is something like the exhaust fumes
produced by automobile engines. If we liken gasoline to
food and air to oxygen, active oxygen would correspond
to the exhaust fumes produced after the gasoline has
As already mentioned, it is believed that in burning up
our food, around two percent of the oxygen we breathe in
through our lungs becomes active oxygen. We breathe
about twenty times per minute, and active oxygen is
being produced in our bodies each time we breathe. Since
the volume of air we breathe in with each breath is 500
cc, we are breathing in about 10,000 cc of air per
minute. As twenty percent of this air, or 2,000 cc,
consists of oxygen, two percent of this amount, or 40
cc, becomes active oxygen. Thus, each minute about 40 cc
of active oxygen is being produced in our bodies. This
amounts to 24,000 cc per hour and 57,600 cc per day of
Considering this moment-by-moment production of large
amounts of active oxygen in our bodies, it is no wonder
that we tend to fall prey to disease. We, on the other
hand, have in our bodies several enzymes, such as
SOD(superoxide dismutase), catalase and glutathione
peroxidase, which remove this active oxygen. As we get
older, however, the function of these enzymes alone
becomes insufficient to dispose of the active oxygen
effectively. As a result, we fall to prey to various
diseases. This means that if we could dispose of the
"active oxygen" effectively, we would be able to achieve
good health and longevity.
The functional mechanism of active oxygen is oxidation.
In order to suppress the (particularly strong) oxidizing
function of active oxygen, it follows that we require a
substance that has the opposite function to oxidation.
The opposite function to oxidation is reduction, and
reduction originally refers to the function of hydrogen.
Consequently, we can say that the originator of
reduction is none other than hydrogen.
SIX : What Is Active Hydrogen
It turns out that the true form of reduction is the
function of hydrogen. Incidentally, various substances
have been proposed as substances capable of removing
active oxygen; that is, substances with reduction effect
(anti-oxidants). Among these, the most effective one is
undoubtedly active hydrogen. The other so-called
anti-oxidant substances cannot compare to it.
As mentioned previously, active oxygen is oxygen with a
particularly strong oxidizing function. What we normally
call "hydrogen" refers to molecular hydrogen or H2.
In contrast, atomic hydrogen or H is specially called
"active hydrogen" because it has a particularly strong
reducing function. Let us look at Table 1 in the last
section of this booklet.
The water around us (such as tap water) is hydrogen poor
water, but if you infuse this water with hydrogen gas
taken from a hydrogen gas cylinder, it can reach up to a
value of 1.49 ppm (hydrogen saturated water). Meanwhile,
by inserting the hydrogen producing mineral stick into
the same water, you can obtain water that is abundant in
hydrogen, which I call Hydrogen Enriched Water.
Now, what happens when we incorporate Hydrogen Rich
Water into our everyday lives ? In a nutshell, there
will be a huge decrease in our probability of getting
Why is it possible to make this statement? Because the
thinking goes as follows:
When Hydrogen Rich Water, water rich in molecular
hydrogen, enters our body, this molecular hydrogen is
broken down into atomic hydrogen in the body. The active
hydrogen bonds with active oxygen (thought to cause all
kinds of diseases) to produce safe, non-toxic water that
leaves the body in the form of urine and sweat.
In short, we may consider that when Hydrogen Rich Water
enters our body, it gets rid of the active oxygen that
is produced in the body from moment to moment. Therefore
there is a significant decrease in our probability of
SEVEN : What Are Hydrogenases
Hydrogenases are enzymes that can reversibly split
molecular hydrogen to produce atomic hydrogen. It is
believed that we apparently have such hydrogenases in
our bodies. Incidentally, all living organisms on this
earth, both plant and animal, are termed "DNA
organisms." This means that all living organisms on the
earth share common ancestor. I will now write about our
ancestor born 3.8 billion years ago.
In 1997,an article called "Biological Activation of
Hydrogen" by R.P. Happe of Amsterdam University was
submitted in the English Journal" "Nature", Vol. 385,pp
126,'97. The main thrust of this article is as follows:
Hydrogenases are enzymes that can reversibly split
molecular hydrogen. ...the crystal structure of a Ni/Fe
hydrogenase (from the bacterium Desulfovibrio gigas) was
reported. ...Ni/Fe hydrogenases are among the oldest
enzymes (3.8 billion years old), demonstrating that
early life forms had developed an effective way to
activate molecular hydrogen at ambient temperature and
My own explanation of this article is as follows.
It is active oxygen that threatens the survival of
For living organisms to survive, it was necessary to
develop a mechanism for
scavenging active oxygen.
3. The best way to scavenge active oxygen is by
means of atomic (active) hydrogen.
4. To produce atomic (active) hydrogen, it is
necessary to split molecular hydrogen.
5. The hydrogenase developed by bacteria 3.8 billion
years ago, was an enzyme that split
molecular to produce atomic hydrogen.
seen, then, that to ensure their own survival, it was
necessary for living organisms to achieve the ability to
produce active hydrogen in order to scavenge active
oxygen; hydrogenase developed by the oldest bacteria 3.8
billion years old was one of theses enzymes. Moreover,
we may consider that this hydrogenase was the ancestor
found in the bodies of higher creatures including
EIGHT : Making Hydrogen-Rich Water
Now we will talk about the actual method of making
Hydrogen Rich Water. The well known method in Japan is
the electrolysis of water (the principle of water
electrolysis is to split water, a compound of hydrogen
and oxygen, back into original hydrogen and oxygen.).
The two kinds of water obtained by this process have
been called ionized alkaline water (water with increased
hydrogen) and ionized acidic water (water with increased
oxygen), which you have probably heard of.
I studied electrolyzed water for many years, and it is
true that this cathodic water contains a large amount of
hydrogen immediately after it is produced. However,
since hydrogen is the lightest element in the universe,
this water loses its hydrogen rapidly, and in 2001 it
was revealed that it reverts to ordinary water only
several minutes after it is produced. Therefore I
decided to call this cathodic water "Temporarily
Hydrogen Rich Water " ( hydrogen rich only directly
after electrolysis ).
In contrast, the water I have named "Constantly Hydrogen
Rich Water", and which I am now presenting as a new
proposal, is water obtained according to chemical
formula written below. It is a reaction in which
magnesium metal reacts with water to produce magnesium
hydroxide, while producing at the same time atomic
hydrogen which then makes molecular hydrogen.
Mg ＋ 2H2O → Mg(OH)2 ＋ 2H → Mg(OH)2 ＋ H2
Mg = Magnesium Metal H2O = Water
Mg(OH)2 = Magnesium Hydroxide H = Atomic Hydrogen
H2 = Molecular Hydrogen (Hydrogen Gas)
Incidentally, general textbooks say that magnesium does
not react with cold water or room-temperature water.
Actually, however, we have verified experimentally that
magnesium reacts well even with cold water to produce

Komatsu Technical High School (http://www.kth.ed.jp/pub/staff/gie/index.html)
for the following: " ...magnesium powder is not soluble
in water. It reacts gradually with cold water and
intensely with hot water, producing hydrogen. It
dissolves in dilute acids and alkalines, producing
Our new proposal concerns the Hydrogen Producing Mineral
Stick made of a magnesium base mixed with natural
pebbles. Simply by inserting this stick into water, you
can make Hydrogen Rich Water easily, reliably and
NINE : Feces Lose Their Unpleasant Odor
or two after people begin to use Hydrogen Rich Water,
they notice that their feces have literally changed in
comparison to when they were using tap water (hydrogen
That is, the "blackish brown, bad-smelling, hard, heavy
feces" of the tap water days changed to "light brown,
soft, light feces without a strong bad odor," similar to
the bowel movements that appear in the diapers of a
We adults tend to think that it is natural for adults
feces to have a bad smell, but this is actually a great
misconception. Every breastfeeding mother knows from her
experience that when her baby has light- colored soft
stool with very little bad odor, she can be sure that
the baby is healthy, drinking plenty of breast milk, and
growing well. On the other hand, when the baby has "blackish,bad-smelling,hard
stool," the baby is cranky and feverish, and sometimes
vomits up milk.
The condition of producing offensive feces is generally
called abnormal fermentation of gastrointestinal tract,
which indicates the opposite of normal fermentation,
but, simply put, it is "decay."
In other words, if the food we take in by mouth has a
rotten smell (bad smell) when it is excreted from the
anus, this means abnormal fermentation has taken place.
Let us look at a simple explanation concerning the
substances that cause disgusting feces brought about by
abnormal gastrointestinal fermentation (See Illustration
Some of the substances that cause disgusting feces are
hydrogen sulfide, ammonia, histamine, indole, phenol or
nitrosamine, all of which are toxic, pathogenic,
Hydrogen Sulfide : A strongly toxic substance
with a distinctive rotten-egg odor.
Ammonia : A strongly toxic substance with a
distinctive irritating odor commonly found in public
Histamine : A substance that triggers
Indole : A toxic, carcinogenic substances
with a smell like rotten onions.
Phenol : Recognized to be carcinogens due to
Nitrosamine : Known as a first-class
sense, failing to deal with offensive feces is like
having a time bomb in your body. You can, however,
defuse this time bomb by drinking Hydrogen Rich Water.
TEN : Modern Medicine Is Nothing But 'Downstream'
I have concluded that modern medicine is nothing more
than "medicine to alleviate downstream pollution while
leaving upstream pollution alone." Let me explain the
basis of this argument.
When we digest the food we take in by mouth in our
stomach and intestines, these digested nutrients are
absorbed through the intestinal walls. The nutrients
absorbed through the intestinal walls pass through the
portal veins and are carried to the liver in that order.
The nutrients that are carried to the liver undergo
various metabolic processes, after which they pass
through the hepatic vein into vena cava inferior and
carried to the organs all over the body by general
That is to say, they are transported in this order:
liver → hepatic vein → vena cava inferior → general
circulation → organs all over the body. As a whole, the
order is: digestive system → portal vein → liver →
organs all over the body.
If we think of the liver as a kind of "checkpoint
station," the parts of the process that occur before
reaching the liver can be referred to as "upstream," and
the parts that take place after leaving the liver as
As shown in Illustration 2, the portion from the mouth
to the liver can be called as "upstream" ( Lake Ontario
: checkpoint before liver) while the organs that come
after the liver can be as called as "downstream" (River
Saint Lawrence : checkpoint after liver). Looking at
metabolism this way, we see that when the "upstream" is
polluted, the "downstream" will become polluted as well.
Thus, the disease-causing substances of upstream will
cause diseases of downstream.
Now I think you understand my statement that "Modern
Medicine is medicine to alleviate downstream pollution
while leaving upstream pollution alone." What, then,
does "upstream pollution" mean?
It means "production of offensive feces" by "abnormal
gastrointestinal fermentation." Because the substances
that cause offensive feces are substances that result
from the putrefaction of protein (eggs, fish or meat),
they are called "putrefied metabolites." In short, it is
as if people who always excrete offensive feces were
eating rotten eggs, fish and meat everyday. The
difference is that if they were eating rotten food, they
would get sick immediately, while in this case the food
rots after they eat it, so it takes more time for them
to get sick. Therefore, it is important to lead a
lifestyle which does not produce offensive feces. But
now we have what can change offensive feces into clean
feces as if by magic, that is Hydrogen Rich Water!
When Hydrogen Rich Water can be obtained simply,
reliably and cheaply, I think the world will change
dramatically. That is, maintaining good health and
preventing disease will no longer be considered topics
worth discussing, and people will not constantly be
making a fuss of diseases ("It's cancer!" "It's
diabetes!" "It's hay fever!") as is presently the case.
Also, if you have drunk a little too much alcohol or
smoked a little too much, or don't feel well, or seem to
be catching a cold, or have caught influenza, it would
be easy to get rid of the symptoms simply by consciously
increasing your intake of Hydrogen Rich Water.
I would like to end with the philosophy I have learned
from Hydrogen Rich Water during these past eighteen
years. I think hydrogen should be called "the source."
That is to say, hydrogen, the element with the atomic
number One, is the "source" of all the other elements,
and the sun, which nurtures all things with its solar
energy, is actually a big ball of hydrogen.
At the same time it is hydrogen atom, or active
hydrogen, that protects us living organisms from
disease. My conclusion follows below.
I propose that the Creator of the universe, and the
Creator of all living things, created hydrogen as the
first element in order to protect all its living
creatures from disease.
Dissolved Hydrogen Content of Hydrogen Rich Water
 1 stick
It can be said that tap water hardly contains
hydrogen gas ().
2. Hydrogen gas from gas cylinder is infused into
the tap water until Hydrogen content is considered
to reach its maximum (saturated) level().
3. One, two or three sticks are inserted into the
corresponding bottles filled with 1 liter of water
and each hydrogen content was estimated after 12
hours passed. It can be said that hydrogen content
of the bottle with 3 sticks reaches 80 % of the
maximum level of ()( 1.203 vs 1.490 ).
TWO: Water Regulating Theory
(1) When oxygen ( O2 ) breathed in
through the lungs oxidizes food taken by mouth, it is
reduced by the food and produces active oxygen O2- (
superoxide anion radical).
(2) O2- is further reduced by hydrogen atom H ( active
hydrogen radical ), producing active oxygen H2O2 (
hydrogen peroxide ).
(3) H2O2 is further reduced, producing active oxygen
HO・（ hydroxyl radical ）and hydroxide anion ( HO- )．
(4) HO・ is reduced by hydrogen atom, producing water (
(5) HO- is also reduced by proton ( H+ ), producing
Oxygen from the lungs keeps producing
active oxygen species ( O2-, H2O2, HO・) in the body, but
these kinds of active oxygen species are reduced
successively through bonding with atomic hydrogen(
active hydrogen ) and eventually revert back to the

HYDROGEN-RICH WATER STICK
The purpose of the Hydrogen-Rich Water Stick is to
create Hydrogen-Rich Water simply by inserting this
stick into the water we usually drink.
After inserting the Hydrogen Stick into the bottle of
water, please be careful always to leave it in during
use. Because hydrogen is the lightest element, the
hydrogen released in the water will be lost rapidly if
the stick is removed and the water will revert to its
original state (as ordinary water without hydrogen).
In principle, the stick is meant for use with tap water
or purified tap water, but it can also be used with
store-bought bottled water. Wash the stick well in
running water, insert it into a bottle of water, and
close the cap tightly.
For maintaining good health and preventing disease, the
standard usage is one stick per 1.5-2.0 liters of water.
For eliminating disease, consider using is two to three
sticks per 1.5-2.0 liters of water.
Hydrogen-Rich Water Sticks last up to six-months.
