Views “Cool Traditions” Stay in Tune with Modern Life
A Peek into the Pearl Culture of Mie Prefecture

Julian Ryall [Profile]


It takes human talent, a gift from nature, and more than four years to produce the perfect pearl. We visited a community famed for these lustrous treasures to learn more about their production and the prospects for their future.

Slowly and with extreme caution, a technician slips a razor-sharp scalpel into an open oyster shell and makes a tiny incision in the glistening innards of the creature within. Deftly, exchanging the scalpel for a pair of tweezers, the technician next inserts a chip of mantle and a spherical nucleus around which secretions of nacre will gradually form to create the perfect pearl.

Delicate operation: inserting the nucleus that will eventually become a pearl into the open shell of an oyster.

After removing the wooden stopper that has held it slightly open for the procedure, the technician adds the shell to a crate holding dozens of similarly impregnated Akoya oysters that are waiting to be returned to the waters of Ago Bay.

Treating Oysters as Our Own Children

Inoue Hikaru’s family has been culturing pearls in a picturesque inlet on the bay for three generations. He got his own start in the business 42 years ago, yet he still feels a tingle of excitement every time he opens a shell and discovers a lustrous pearl inside. “My motivation is to produce pearls of such quality that when a hundred people see them, every one of those people will call them perfect.”

“Culturing pearls is a very difficult thing to do well. These oysters—just like humans—have to endure lots of environmental stresses before they can grow up and produce,” he says. “We treat each of these oysters as if it were our own child. We nurture them, and when they give us a pearl in the end, then we know that we have done a good job of raising them.”

The Way of Life, Akoya Pearls

Inoue is the owner of Inoue Pearl, based in the Mie Prefecture city of Shima. He employs a team of skilled local women to carry out the delicate work of planting seeds within the oyster shells, with each woman working on around 500 shells in an eight-hour working day. The work is exacting, he agrees, with the innards of each shell slightly different, meaning that the women use their experience as well as their skill to ensure that the oyster can survive the procedure.

The women go about their painstaking work in a wooden hut atop the seawall protecting the village, just meters from a gangplank that leads down to a rickety-looking mesh of poles and planks floating on the surface of Ago Bay.

Juvenile oysters that fit comfortably in the palm of the hand are held in pairs in nets suspended below the pearl rafts, where they feed on the rich waters of the bay, which are constantly replenished with nutrients that wash off the surrounding hillsides.

More mature oysters are seeded and stored in boxes that are similarly hung below the rafts for two years, while their pearls develop. The entire process takes four years to come to fruition.

Challenge lies ahead

It is an idyllic place, agrees Morishita Bunnai, at 70 years old the head of the local pearl association, although there are challenges.

“We were hit hard by the impact of the global financial shock in 2008, although the industry has recovered since then,” he says. “Australian pearls have also emerged as a rival, largely because they are bigger, but we have seen off that challenge because of the quality of the pearls that we produce. We’re now looking to expand sales into newly emerging markets like China and Southeast Asia.”

Mie farmers pursue perfection in the lustrous spheres their oysters produce.

A Combination of Human Talent and Natural Bounty

Asked what makes pearls so incomparable, Morishita smiles and says that what sets these luminescent spheres apart is that they are purely the work of nature.

“If you have a diamond or some other precious stone, that isn’t how it was found,” he points out. “It’s been cut, shaped, and polished by people and machines. It may be beautiful, but it is no longer natural. A pearl is organic, though—a natural thing raised with care, coming from something that’s alive rather than from a lump of rock,” he adds. “A pearl is a joint effort between nature and the skill of humans. That’s, what makes all the difference.”
