The Uwakai Sea is characterized by the deep bay with ria coastline and blessed with abundant nature, and it is also in the most privileged natural environment suitable for pearl farming.
Pearls are cultured by making good use of abundant natural blessings.
Beautiful pearls are produced by our reliable technology and thorough work that has continued three generations.


The process takes about a year. The pearls produced after the processes are called “Tonen-mono (harvested within a year)”.
The pearls harvested in the following year after nurtured in the ocean for another year are called “Koshi-mono (harvested over the year).” “Koshi-mono” stays in the ocean a year longer so that the nacre layer becomes thicker and we tend to get higher quality pearls.
However, the mortality rate of Akoya oysters becomes higher and not all the pearls have higher quality, so in other words, it’s taking a big risk.
Doi Pearl makes an effort to increase the quantity of “Koshi-mono” as much as possible in order to produce higher quality pearls.
