Ago Bay Pearl

Countless pearl cultivation rafts float quietly across an intricate maze of inlets. Ago Bay, on the southern edge of the Shima Peninsula in Mie Prefecture, is the sea that made Shima famous as a home of cultured pearls. Its calm, multi-island rias scenery and its glittering pearl story make a visit here a graceful and rewarding experience.

Highlights

Ago Bay is a rias inlet on the southern Shima Peninsula. Its calm, nutrient-rich waters are ideal for pearl cultivation. In 1893, Mikimoto Kokichi succeeded in the world's first pearl cultivation at Ojima (now Mikimoto Pearl Island) off Toba, and the technique spread across the Ago Bay area. Rafts still dot the bay today, and Shima is known as a home of pearls.

The greatest appeal of Ago Bay is the scenery of islands large and small among the cultivation rafts. From Yokoyama Observatory, at an elevation of about 140 meters, you can take in the whole bay with its islands and deeply indented coastline. Admission to the observatory is free, and an adjoining cafe lets you rest while enjoying the view.

Pearl-related experiences add to the charm. Nearby facilities let you open an Akoya oyster and take out a real pearl, and some shops will craft it into an accessory. At Mikimoto Pearl Island in Toba, you can watch ama diver demonstrations and learn the history of pearls.

Seasonal Enjoyment

Spring: Mild weather makes cruises and observatory views pleasant. Summer: The blue sea and green islands form a vivid contrast; prepare for strong sun. Autumn: Clear air offers long views, and the sunsets are especially beautiful. Winter: Fewer visitors mean quiet viewing, with the bay glowing at dusk.
