Why "Easy-to-Drink Water" Becomes a Small Daily Comfort When Living in Thailand|Natural Water to Choose for Life in Thailand

Living in Thailand, I'm surprisingly concerned about the "water"
Life in Thailand is more comfortable than I expected, with many Japanese restaurants and convenient transportation.
However, once you actually live here, many people feel a slight discomfort about the "water" that they drink every day.
- It has a peculiar taste
- It feels heavy to swallow
- The taste of coffee and tea seems to have changed
- I miss Japanese water
Of course, bottled water sold in Thailand meets safety standards.
Nevertheless, "safety" and "easy to drink" are not always the same.
Since it's something you drink every day, you want to choose water that suits you.
The number of Japanese people who think this way is increasing year by year in Thailand.
Why does Thai water feel different from Japanese water?
There are various types of drinking water in Thailand.
Natural water, mineral water, RO water (reverse osmosis treated water), etc., vary in their production methods and components.
Japanese people, in particular, tend to notice differences in:
- Hardness
- Mineral balance
- Mouthfeel
- Aftertaste
Japanese water is generally soft water, which is rare globally, and is characterized by a mild taste.
On the other hand, when living overseas, you have more opportunities to drink water with slightly higher hardness or unique mineral content.
Therefore,
"I'm looking for easy-to-drink water in Thailand"
"I want to know about recommended water for Japanese people in Thailand"
Many people search for these terms.

What kind of water is "easy to drink"?
Everyone has different preferences for easy-to-drink water.
However, common characteristics among many Japanese people include:
1. Being soft water
Soft water with low hardness has a smooth mouthfeel and can be drunk easily.
Many people feel it's gentle on the stomach and intestines, making it a familiar type for Japanese people.
2. Not having too strong a mineral taste
Some overseas mineral waters can have:
- A slightly salty taste
- A metallic taste
- A unique aftertaste
For those not used to it, it can be difficult to drink every day.
3. Good compatibility with coffee and tea
Water is not just for drinking as is.
- Coffee
- Japanese tea
- Black tea
- Miso soup
- Cooking rice
It's deeply involved in our daily diet.
Easy-to-drink water doesn't interfere with the taste of ingredients and brings out their natural deliciousness.
