It is no exaggeration to say that the discovery of “beautiful water” has developed human civilization.

Two hundred thousand years ago, the life expectancy of primitive man was 25 years. There were hygiene issues, but the most important reason was to avoid depriving their own children of scarce food.

It was not until the beginning of the 20th century that life expectancy began to increase in earnest.
The discovery of germ theory led to the birth of antibiotics, and improved sanitation led to the widespread availability of clean water, which dramatically reduced child mortality. Life expectancy then exceeded 40 years for the first time.

This spring is located in Aza Kakihana, Tamaki, Nanjo City, Okinawa Prefecture, and has been selected as one of the 100 best waters by the Ministry of the Environment. Located on a hill in Tamaki, Nanjo City, the area is covered with tropical trees more than 100 years old, and rice paddies spread out from the spring that springs from the cliffside of the village.

In Okinawa, a hija (river) is a puddle created by drawing water from a water vein with a toi (flume).
The hardness is 280ppm, about twice as hard as tap water. The water temperature is maintained at about 23 degrees Celsius all year round.
