Coral International Co.,Ltd.

DONAN is simply made from the fossilized coral ore deposit found on Yonaguni Island. Chougen Yamakawa, the company CEO invested several inland fossilized coral ore deposits in different regions/areas and found the best fossilized coral ore deposits on the specific area on Yonaguni Island.This area was formed by the corals, which were alive in the 3rd Interglacial epoch, approximately 72,000 to 150,000 years ago. This fossilized coral has been well preserved and been calcium carbonate of the first-class quality. Also, the fossilized coral is an aragonite-type and it has not completely been calcite. Such perfect calcium carbonate is rarely seen in the world.
What makes DONAN special is that it contains 73 different minerals and trace minerals, of which calcium is the highest concentration as 40%. Moreover, the aragonite-type fossilized coral calcium carbonate ionizes easily and dissolves 5~6 times faster/better than calcite-type calcium carbonate in water. Although calcium is among the most difficult of the essential minerals for the body to absorb, DONAN allows easy and fast absorption into the body.

DONAN is a calcium supplement made from Yonaguni Fossilized Coral pulverized into a fine powder with granules no greater than three microns. Odorless, tasteless, and easily dissolved into water, DONAN can be drunk after simply being added to cold or hot water, or even an alcoholic beverage. Naturally, it mixes in quite easily with cooked foods.
One to one and a half tablespoons of DONAN is enough to meet the full adult daily requirement for calcium as well as provide supplemental intake of some 70 minerals in which the body is often deficient. These minerals include potassium, magnesium, manganese, and sodium. Although calcium is among the most difficult of the essential minerals for the body to absorb, the processed natural coral base of DONAN allows easy absorption into the body.

Sunsea Mineral is a liquid product that is highly concentrated mineral water using natural fossil coral and natural sea salt. More than 70 kinds of mineral ingredients, such as calcium, magnesium, potassium, and sodium, are contained within.

"Minami-chan" is a filtration product which changes tap water into delicious and safe water. There are detrimental substances such as chlorine and formaldehyde that are present in the tap water. "Minami-chan", which is made of natural fossil coral removes the excess chemical substances contained in tap water, changing it into healthy and delicious water.
Natural fossil coral is a formation of numerous tiny holes. These holes absorb and remove the excess chemical substances in tap water. Moreover, since mineral ingredients in Minami-Chan such as calcium contained in the natural fossil coral begin to dissolve, this also helps creates healthy and delicious water.

Urucal: Yonaguni Fossilized Coral Powder is a calcium supplement for domestic animals and pets. Our fossilized coral mixes in easily with feed and includes potassium, magnesium, manganese, and sodium as well as 70 minerals which are deficient in the body. Moreover, clinical test results show that our new product Urucal-X (fusibility coral powder) was effective in milk fever prevention of the milk cow. Clinical studies/experiments were carried out in the College of Dairy Agriculture.

DONAN Fertilizer: Yonaguni Fossilized Coral powder is a formation that contains numerous tiny holes. These holes absorb and remove the excess chemical substances in soil. In fact, residue-prone agricultural chemicals found in fruit & vegetables was removed by using fossil coral manure as a result of analysis in Japan Food Research Laboratories. Moreover, since mineral ingredients in DONAN Fertilizer such as calcium contained in the natural fossil coral begin to dissolve, this also helps to enrich and create healthy and organic soil.
