Magatama Day

What Is Magatama Day?

September 6th is "Magatama Day," established by Menoya Co., Ltd. of Matsue, Shimane Prefecture — a company that has presented Izumo-style magatama (curved beads) to the Imperial Household and Izumo Taisha Shrine. The date, along with June 9th, was chosen because the numerals 6 and 9 resemble the curved shape of a magatama bead. The anniversary is certified and registered by the Japan Anniversary Association.

What Exactly Is a Magatama?

A magatama is an ornament curved into a C shape, with a hole bored through its rounded end for a cord, traditionally crafted from jade, agate, rock crystal, amber, and similar materials. The name most likely means "curved jewel." The oldest known examples come from Jomon-period archaeological sites, and during the Kofun period they were used as grave goods symbolizing authority and status.

• A sacred treasure: the Yasakani no Magatama, one of Japan's Three Sacred Treasures, is a bead passed down within the Imperial Household
• Origin of the shape: theories include that it was modeled on an animal fang or that it represents an early fetus in the womb, but no one knows for certain
• Origin region: Shimane Prefecture is known for its high-quality agate, and the tradition of Izumo magatama-making continues there today

Why These Two Numeral-Based Dates?

The distinctive curved shape of a magatama closely resembles the numerals 6 and 9. This visual association is why both June 9th and September 6th were chosen as "Magatama Day."
