Japanese Commodity 4- Japanese Pearls


Pearls are gemstones extracted from shellfish and are few in number. Pearls are divided into natural and cultured pearls.

Today, most of the pearls are cultured.


Types of Pearls in the World

Akoya Pearl (Wadama)

Pearls of superior quality are called hanadama pearls.


Most pearls cultured in Japan today are Akoya pearls.


South Sea Black Butterfly Pearl (Tahiti Black Butterfly Pearl)

These pearls, known as black pearls, are produced from the black-lipped pearl oyster of the South Seas (the most typical are from Tahiti in French Polynesia).


South Sea White Butterfly Pearl, White Butterfly Pearl

These pearls come from the white-lipped pearl oyster, the largest pearl oyster in the South Seas (which can be over 30 cm long).


Some pearls can grow up to 19 mm in diameter due to the size of the pearl oyster itself.


Freshwater Pearl

Freshwater pearls are mainly from large bivalve shells called ikecho-gai, and are cultured in Japan in lakes such as Lake Biwa, but many are imported from China.


*There are other types of pearls.


About Pearls in Japan

In Japan, Kokichi Mikimoto of Japan succeeded in producing semicircular pearls from cultured Akoya oysters in Ago Bay in 1893, and in 1905, Kokichi Mikimoto collected spherical pearls with semicircular nuclei in the same bay (various theories exist).


We can see that at first they started out cultivating semi-circular pearls and then succeeded in cultivating round pearls as we know them today.

As for pearls, Ehime Prefecture seems to be number one, although reading the above story about pearl cultivation for the first time, I think it might be Mie Prefecture.
