Why Japanese Rice Doesn't Cook Well in Thailand | Instead of the Rice, Why Not Reconsider the "Water"?
Why doesn't Japanese rice taste the same in Japan as it does elsewhere?
You can buy Japanese rice in Thailand.
Recently, high-quality Koshihikari and Akita Komachi rice have also become more readily available.
Nevertheless,
Have you ever felt that it's "somehow different from the rice eaten in Japan"?
"I feel like it's not sweet enough."
"It doesn't turn out fluffy."
Many people think the cause lies in:
- The rice variety
- The rice cooker
- The storage method
However, there's actually a crucial, often overlooked factor:
"Water."
Approximately 60% of cooked rice is water.
Rice absorbs a large amount of water during cooking.
Most of the weight of cooked rice is water.
This means that if the water changes, the taste and texture of the rice also change.
No matter how high-quality the Japanese rice you use, differences in water can change the impression of the cooked rice.
The relationship between Japanese rice culture and soft water
Japan is known as a country with a high prevalence of soft water.
Soft water is water with relatively low mineral content, such as calcium and magnesium.
Not only Japanese cuisine but also Japanese rice culture has developed in a soft water environment.
Generally, soft water is said to enhance:
- A smooth mouthfeel
- Natural sweetness
- A fluffy texture
Therefore, Japanese rice and soft water are considered to be a good match.
Why the taste of rice changes in Thailand
In Thailand, water quality varies depending on the region and the water source used.
Even if you use a water purifier,
- Mineral balance
- Hardness
- Taste
may differ from that in Japan.
As a result,
even when using the same Japanese rice,
- Texture
- Sweetness
- Aroma
may be perceived differently.
If you want to reproduce the taste of rice eaten in Japan, it's important to pay attention not only to the rice but also to the water.
How does water affect the cooked rice?
Generally, soft water is said to create an environment where rice can easily absorb water.
Therefore, it can lead to cooked rice that is:
- Fluffy
- Sticky
- Sweet
On the other hand, a change in water quality also alters the impression of the cooked rice.
Perhaps because rice is eaten daily, the difference in water quality is easily perceived.

Tips for enjoying even more delicious rice
Water is not the only factor that influences the taste of rice.
For example, various factors are involved, such as:
- Rice variety
- Pre-washed rice or milled rice
- Storage method
- Rice cooker performance
- Water used for cooking
In recent years, with improved milling technology, more pre-washed rice products can be cooked deliciously.
Also, in Thailand, high-quality Japanese rice has become more readily available, making it possible to cook rice in an environment similar to Japan.
However, while many people are particular about their rice and rice cooker, not many pay attention to "water."
Since rice absorbs a large amount of water during cooking, differences in water can change the texture and taste.
Perhaps by paying attention not only to the rice but also to the water for the rice you eat every day, you might discover something new.
Summary
When cooking Japanese rice in Thailand,
you might feel that it's "somehow different from the rice eaten in Japan."
The reason for this may lie not only in the rice but also in the water.
Since you eat rice every day, choosing the right water is an important factor.
If you want to enjoy the authentic taste of Japanese rice, why not pay attention to the water you use?
