Safe and High-Quality Fucoidan

Tonga in The South Pacific

We use safe and high-quality Fucoidan from the Kingdom of Tonga.

The Kingdom of Tonga comprises around 170 large and small islands in the South Pacific Ocean. It is located at the point where the International Date Line and the Tropic of Capricorn intersect. Its total surface area is about 697K㎡, and the population is 100,000. The Tonga ocean is made up of cool seawater rising from the Tonga trench which is said to be the second deepest sea in the world and is rich in minerals. Any harmful substance such as heavy metals has not been detected in this ocean area.​ ​


Mozuku grows in the deep ocean water with abundant minerals from Tonga trench.

Mineral abundant Mozuku

The Antarctic ocean current has plenty of minerals and is pollution-free.

Tongan Mozuku grown under such conditions is excellent in safety and rich in minerals, even though it is said that seaweeds accumulate heavy metals such as arsenic and lead. Furthermore, bullets or cannonballs has not been found in Tonga ocean because there is no history of war. That is to say, the ocean has originally no water pollution.

Natural Fucoidan

In Tonga, efforts of "protecting nature" have been undertaking in the entire island.

Efforts to protect nature

We use our own collection method to limit the harvesting period from August to October, local winter, to secure resources while protecting the ecological system.

In addition, the divers dive into the ocean and collect natural Mozuku carefully by their own hands.

As a result, efficient components contained in Fucoidan are harvested without any damage.

Thorough Quality Control

We refine high purity and high-quality Fucoidan through our unique manufacturing method from the extraction of Fucoidan through ultrafiltration, spray drying and sterilization.
