Pearls and Japan
Japan's bond with pearl culture runs deeper than any other country's. From the scientific breakthroughs of the late 19th century to the global trade networks of today, Japan remains the center of the pearl world — and the best place on earth to source the highest quality cultured pearls.

The birthplace of cultured pearls.
For centuries, pearls were found only by chance — harvested by divers from wild oysters in the Persian Gulf, the Indian Ocean, and the coastal waters of Japan. The idea of cultivating a pearl inside a living oyster was the subject of scientific experimentation across Europe, China, and Japan throughout the 18th and 19th centuries.
It was in Japan, in the late 1800s and early 1900s, that the technique was finally perfected. Japanese researchers and entrepreneurs developed a reliable method for nucleating saltwater oysters and producing round cultured pearls of consistent quality. The Japanese Akoya pearl became the first commercially viable cultured pearl in the world.
This breakthrough transformed the pearl industry. What had been a rare luxury available only to royalty and the very wealthy became accessible to a far broader market, while retaining its status as a natural, organic gem grown inside a living creature.
A century of pearl innovation.
First Experiments
Japanese researchers begin systematic experiments in pearl cultivation, building on centuries of knowledge about oyster biology and nacre formation.
Commercial Akoya
The technique for producing round cultured pearls is perfected. Japanese Akoya pearls become the first commercially viable cultured pearl, transforming the global market.
Global Hub
Pearl farming expands to Australia, French Polynesia, and China — but the majority of the world's high-quality cultured pearls still arrive in Japan for final processing, grading, and sorting.
Global expertise, Japanese roots.
Over the decades, pearl culturing expanded beyond Japan to Australia, Indonesia, the Philippines, and French Polynesia — producing the larger South Sea and Tahitian pearl varieties. But even as production spread, the expertise stayed concentrated in Japan.
Japanese pearl professionals remain the world's most experienced processors, sorters, and matchers. The majority of the world's high-quality cultured pearls still arrive in Japan for final processing, grading, and sorting before being exported to markets around the globe.
This is not tradition for tradition's sake. Japanese processors can distinguish finer gradations of luster, surface quality, and color than most anywhere else. The infrastructure, the trained eye, and the generations of accumulated knowledge make Japan the most reliable place to source pearls at any quality level.
- Processing hub The majority of the world's cultured pearls pass through Japan for sorting, grading, and matching before export
- Grading expertise Japanese professionals set the global standard for pearl evaluation — luster, surface, nacre thickness, and color matching
- All pearl types Japanese Akoya, Australian and Indonesian South Sea, Tahitian, and Freshwater pearls are all traded and processed in Japan
- Supply chain advantage Buying in Japan means buying closer to the source — fewer intermediaries, better selection, more competitive pricing
Our place in the chain.
Pearls.jp is the retail brand of Amit Trading Co., Ltd., a Tokyo-based pearl exporter established in 1969. For over 55 years, Amit Trading has operated as one of the early links in the global pearl supply chain — sourcing pearls from farms across Japan and the Pacific, processing and matching them in Tokyo, and exporting to jewelers and retailers worldwide.
That position in the chain is the foundation of everything we offer. When you purchase from Pearls.jp, you are buying from a company that handles pearls before most retailers ever see them. The selection is broader, the quality control is tighter, and the pricing reflects proximity to origin rather than layers of markup.
We take pride in being part of the cultural and commercial bond between Japan and the global pearl industry. It is a responsibility we have carried for two generations — and one we intend to carry forward.
