Kagoshima Tarumizu's Water and Food Culture | Japan's Natural Delicacies
Why is Japanese food so delicious?
There are various reasons, such as the ingredients, cooking techniques, and the bounty of the four seasons.
In fact, "water" is also one of the important factors.
Tarumizu City in Kagoshima Prefecture is known as a region blessed with rich nature overlooking Sakurajima and delicious water.
And that water supports Japanese food culture, including Japanese cuisine, green tea, rice, and fresh seafood.
This time, we will introduce the nature of Tarumizu City, Kagoshima Prefecture, and the food culture nurtured by its water.

What is Tarumizu City, Kagoshima Prefecture?
Tarumizu City is located on the Osumi Peninsula in Kagoshima Prefecture and is a naturally rich area overlooking Sakurajima across Kinko Bay.
Blessed with a warm climate, sea, mountains, and abundant water, agriculture and fisheries thrive.
It is also known as a production area for natural water and hot spring water, and a culture of living with nature has been passed down to this day.

Water supports Japanese food culture.
In Japan, water is not just a drink.
For example:
・Water for cooking rice
・Water for making dashi (soup stock)
・Water for brewing green tea
・Water used in cooking
It is used in various situations in daily meals.
It is said that the taste of dishes and drinks changes when the water changes.
Therefore, in Japan, a culture of valuing good water has been cultivated since ancient times.
Japanese soft water culture
Japan is a country with a globally high proportion of soft water.
Soft water is water with low mineral content, such as calcium and magnesium.
Generally, it is said to have the following characteristics:
・Smooth mouthfeel
・Minimal unique taste
・Enhances the flavor of ingredients
・Pairs well with Japanese cuisine
Therefore, Japanese food culture, including Japanese cuisine, green tea, dashi (soup stock), and rice, has developed alongside soft water.
