Where does our water come from? A guide to "water sources"—something you should know since you drink it every day.

"Water," something we drink casually every day.

Supermarkets and convenience stores are lined with a wide variety of bottled water.

While many people choose based on price, brand, hardness, or ease of drinking, there is one more thing to pay attention to:

"Where does that water come from?"

Every water has a place where it originated.

The sources and water collection sites vary, such as water pumped from underground or water that springs naturally from the earth.

Because it is something you consume every day, knowing the source and collection site, rather than just the hardness or pH, can be another perspective for choosing your water.

What is a water source?

A "water source" refers to the place that serves as the origin for the water we use.

There are various sources for the water around us, including rivers, lakes, groundwater, and springs.

The same applies to bottled water.

The location where it is collected and the origins of the water differ by product, and these differences relate to characteristics such as the mineral content and hardness of the water.

When you pick up a bottle of water, try looking not just at the product name or price, but also at the "source of collection" listed on the label; you might discover something new about the water.

Different sources mean different water characteristics

Even if water looks the same and is transparent, not all water is identical.

Water contains minerals like calcium and magnesium, and its hardness varies depending on the amount of these minerals.

Generally, water with low hardness is called "soft water," and water with high hardness is called "hard water."

In Japan, soft water is common, and for those who have lived in Japan, it is quite common to be accustomed to the smooth taste of soft water.

On the other hand, looking at the world, the hardness and mineral characteristics of water vary by region.

Therefore, when learning about water, it helps to look at:

Where was it collected?
How hard is it?
What kind of characteristics does the water have?

Looking at this information together makes it easier to understand the differences between each type of water.

For those who want to know more about soft and hard water, we explain it in this article.

Where did the water come from?

Do you check the "source of collection" when choosing water?

Everyone has different criteria for choosing water.

Points of emphasis, such as price, taste, hardness, volume, and accessibility, change depending on your lifestyle.

Among those, it might be good to add one more way of choosing:

"Checking the collection site."

For example, if there is a bottled water you always drink, try checking the label once.

Where was this water collected?

Is it soft water or hard water?

What are its characteristics?

Even for water you drink casually every day, if you look into it a little, you might discover things about that bottle that you surprisingly did not know.

Because you drink it every day, learn a little about your water

We drink water every day.

That is precisely why you don't need to think about it in a complicated way.

When choosing "which water shall I drink today," instead of just looking at the price and package,

"Where did this water come from?"

Trying to be just a little bit more conscious of this is an opportunity to learn about the water you drink every day.

ONSENSUI99 is also one such water, pumped from 750 meters underground in Tarumizu City, Kagoshima Prefecture, and delivered from Kagoshima to Thailand.

Whether you knew about ONSENSUI99 in Japan or discovered it for the first time in Thailand, we hope you learn about the background of that bottle.
