Kōkichi Mikimoto, born in Toba, Mie Prefecture, began cultivating pearls in the late 19th century to address supply shortages. After establishing a farm in 1888, he successfully produced hemispherical cultured pearls in 1893. This breakthrough, achieved through seeding oysters with mother-of-pearl, marked the beginning of his work in pearl cultivation, though spherical pearls remained elusive for over a decade.

    Mikimoto successfully created hemispherical cultured pearls on July 11, 1893, after years of failures and near bankruptcy.

Background and detail

Background. Mikimoto was born in Toba, Shima Province (now Mie Prefecture), in 1858. His interest in pearls began in 1878 when he noticed flaws in pearls at an exhibition. As chairman of the Shima Marine Products Improvement Association, he sought alternative production methods due to severe supply shortages. In 1888, he obtained a loan to start his first pearl oyster farm at the Shinmei inlet on Ago Bay in Mie Prefecture.

Cultivation Method. Mikimoto's early work involved seeding oysters with small amounts of mother-of-pearl. This process resulted in hemispherical cultured pearls, known as mabes. The method was distinct from later techniques involving mantle tissue insertion. His initial success in 1893 was a significant step, though it took twelve more years to achieve fully spherical pearls that were commercially viable.
