Tamanooya Shrine — 玉祖神社

Tamanooya Shrine in Hōfu, Yamaguchi Prefecture, is the sole shrine in Japan dedicated to Tamanooya no Mikoto, the deity credited with crafting the sacred jewels used to lure the sun goddess Amaterasu from her cave. These curved magatama beads — one of the three Imperial Regalia — were strung together and hung from the branches of a sacred sakaki tree, their luminous green jade catching firelight to create the illusion of returned stars. The shrine sits at the historical center of ancient jewel-making guilds, where craftsmen claimed direct descent from the god and passed lapidary secrets through bloodlines for over a millennium.

The shrine was established in 714 CE during the Nara period, though worship of Tamanooya no Mikoto at this site likely predates official records by centuries. Hōfu was historically known as Saba, a district renowned for jewel craftsmanship since the Kofun period. Imperial chronicles record that jewel-makers from this region supplied the Yamato court with ceremonial magatama and other sacred ornaments. The shrine’s location marks the ancestral home of the Tamanooya clan, hereditary jewelers who maintained monopoly rights over imperial commissions. During the Heian period, the shrine received court patronage and land grants. The current main hall was reconstructed in 1729 following a fire, preserving the architectural style of the Muromachi period.

Tamanooya no Mikoto (玉祖命) is the divine craftsman who created the sacred jewels for the gods’ assembly when they devised a plan to coax Amaterasu from the Heavenly Rock Cave. According to the Kojiki, he fashioned the yasakani no magatama — the curved jewel that became one of Japan’s three Imperial Regalia alongside the mirror and sword. His name literally means “Ancestor of Jewels,” and he represents the divine origin of all craft excellence, particularly lapidary arts. He is patron to artisans, jewelers, and those seeking perfection in skilled work. The shrine also enshrines his descendants who continued the jewel-making tradition.

When Amaterasu sealed herself in the Heavenly Rock Cave, plunging the world into darkness, the eight million gods convened to devise a stratagem. Tamanooya no Mikoto was tasked with creating jewels of such beauty they would symbolize the return of light itself. He crafted five hundred curved magatama beads from jade, each representing a star. These were strung on a sacred cord and hung from a sakaki tree along with the mirror forged by Ishikoridome no Mikoto. When the goddess Ame-no-Uzume performed her provocative dance and the gods roared with laughter, Amaterasu’s curiosity was piqued. She emerged slightly from the cave, and the jewels caught the firelight — their green translucence seeming to hold captured starlight. This visual trick, combined with the mirror’s reflection, convinced her that another sun had appeared, and she emerged fully, restoring light to the world.

The main hall follows the kasuga-zukuri architectural style, characterized by a gabled roof and raised floor, painted in muted earth tones rather than the vermilion common to many shrines. The worship hall features wooden carvings depicting magatama beads and jewel-making tools. A small museum on the grounds displays ancient magatama excavated from nearby kofun burial mounds, demonstrating the continuity of local jewel-crafting from the 5th century onward. The shrine’s sacred tree, a massive camphor estimated at over 800 years old, is designated a natural monument. Stone markers throughout the precincts indicate the former locations of jewel workshops where craftsmen once worked under the shrine’s oversight.

• Tama Matsuri (Jewel Festival, October 10) — The main annual festival features a ritual re-enactment of magatama creation, with local artisans demonstrating traditional jewel-polishing techniques using ancient methods
• Hatsumode — New Year’s visitors receive magatama-shaped omamori said to bring success in craftsmanship and skilled professions
• Craftsman’s Thanksgiving (November 23) — Artisans from across the region present their finest works as offerings, seeking the deity’s blessing on their skills

October offers the ideal combination of the Jewel Festival and autumn weather. The Tama Matsuri on October 10 is the only time when traditional jewel-making demonstrations occur on shrine grounds, providing rare insight into techniques largely lost to history. Early morning visits in any season offer solitude beneath the ancient camphor tree, whose massive canopy creates a cathedral-like space. Avoid New Year’s first three days when crowds overwhelm the modest grounds.
