A Complete Buyer’s Guide for Akoya, South Sea, Tahitian, and Freshwater Pearls
1. Japan — The Legendary Home of Akoya Pearls
Japan is the undisputed leader of high-quality Akoya pearls, famous for their sharp, reflective luster and classic round shape. These are the pearls that most people imagine when they think of a “traditional white pearl necklace.”
1.1 Overview
Japan is the birthplace of modern pearl cultivation. In the late 1800s, Kokichi Mikimoto revolutionized the industry by developing techniques to culture pearls consistently, making Japan a global pearl powerhouse.
Today, Japanese Akoya pearls remain the gold standard for quality.
Why they’re famous:
- Mirror-like luster
- Excellent roundness

- Premium grading system
1.2 Key Farming Regions
Over 90% of Japan’s Akoya pearls come from five prefectures:
- Mie
- Ehime
- Nagasaki
- Oita
- Kumamoto
Ago Bay (Ise-Shima) — “The Cradle of Pearls”
Ago Bay in Mie is historically Japan’s most iconic pearl-farming region. Pearl harvesting in this area dates back to the Nara period (8th century). Mikimoto’s first commercial pearl farms were established here.
Due to environmental changes, modern large-scale farming has shifted to Ehime and Kumamoto, but Ago Bay remains a symbol of Japan’s pearl heritage.

Japan cultivates Pinctada fucata martensii—the Akoya oyster. To reduce mortality caused by inbreeding, Japanese growers use hybrid oysters from China’s Beihai region to improve resilience.

Japan enforces clear rules for nacre thickness:
- Minimum 0.3 mm to enter the market
- 0.4 mm or more for Hanadama grade (top-tier Akoya)
- Most high-quality Akoya pearls measure 0.35–0.40 mm
