Why It Is Called “The Jewel of Fibers”

Long before Columbus reached the Caribbean in 1492, the West Indies were already cultivating cotton with exceptionally long fibers. This cotton—Gossypium barbadense—is the ancestor of Sea Island cotton.
When barbadense was later refined in the United States and reborn as Sea Island cotton, its extraordinary quality attracted global attention. Cultivation was attempted around the world, but all efforts failed due to unsuitable local climates.
To overcome this, Sea Island cotton was crossbred with local varieties, giving rise to today’s extra-long staple cottons such as Egyptian (Giza) and Indian (Suvin) cotton. In other words, the DNA of Sea Island cotton is essential to producing the world’s finest cotton.
Meanwhile, barbadense cotton—enhanced in quality through cultivation in the United States—was reintroduced to the Caribbean in the early 20th century under the guidance of the British agricultural authorities. This cotton became known as West Indian Sea Island Cotton.
Celebrated for its “silk-like luster” and “cashmere-like touch,” it has been passed down through generations as “the Jewel of Fibers.”

Value Through Rarity

Sea Island cotton cultivation in the Caribbean initially centered on the Lesser Antilles, primarily former British territories. However, production gradually declined due to several constraints: limited land area (for example, Barbados is roughly the same size as Tanegashima Island in Japan), labor shortages resulting from small populations, and frequent natural disasters caused by the region’s location along major hurricane routes.
As a result, the number of producing islands decreased from six to just one, and today only Jamaica continues cultivation, where these challenges are relatively less severe.
Even so, production in Jamaica alone cannot meet global demand. This is why West Indian Sea Island Cotton remains one of the rarest and most precious cottons in the world.

Cultivation Methods That Shape Quality

Unlike modern mechanized cotton farming, West Indian Sea Island Cotton in the Caribbean is still grown largely by hand.
Yields are low—about 40% of conventional cotton—and pest control remains a major challenge.
Cotton bolls open gradually from the bottom upward and are hand-picked one by one at full maturity, much like harvesting ripe fruit. This careful process is a key reason for its exceptional quality.

Sustainability and Community Impact

Our cotton program is supported by the Jamaica Agricultural Development Foundation (JADF), a nonprofit organization established to diversify Jamaican agriculture.
Through JADF’s technical assistance, all Sea Island Cotton is grown under contract farming, ensuring stable and well-managed operations.
During harvest season, the project creates significant local employment—up to a cumulative total of around 3,000 workers—with payment levels that far exceed Fair Trade certification standards.
This fair and inclusive business model ensures mutual benefit for all involved and underpins the long-term sustainability of the program.

Traceability and Protection Against Counterfeits

We work directly with contracted farmers and import the raw cotton to Japan ourselves. The cotton is then spun into 100% Sea Island Cotton yarn on a dedicated production line equipped with state-of-the-art spinning machinery at a domestic mill.
By managing every stage—from cultivation in the field to yarn production in Japan—we have established a level of traceability that is unmatched and impossible to replicate, ensuring authenticity and protection against counterfeit products.
To guarantee that this yarn is used in the finished product, we provide a hologram hangtag with a unique serial number.
Through this serial number, products made with the Sea Island Cotton yarn we supply can be traced back to the yarn production lot and even the year in which the raw cotton was harvested, ensuring full transparency and authenticity.
