Suga Shrine — 須我神社

Suga Shrine in Unnan, Shimane Prefecture, claims to be the site of Japan’s first palace — the house Susanoo no Mikoto built for his bride after slaying the eight-headed serpent Yamata no Orochi. More importantly, it is where he composed what is considered Japan’s oldest poem, a thirty-one syllable verse celebrating the rising clouds of Izumo and the joy of building a home. The poem is recorded in both the Kojiki and Nihon Shoki, and the shrine preserves the exact spot where mythology claims Japanese poetry was born. Behind the main hall stands an enormous sugi cedar said to be a direct descendant of the tree Susanoo planted himself.

Suga Shrine’s foundation reaches back to the mythological age itself, making precise dating impossible. Local tradition places the shrine’s establishment at the moment Susanoo built his palace here after rescuing Kushinadahime from the serpent. Historical records confirm a shrine existed at this location by the early Heian period (794-1185 CE), when it was already recognized as a sacred site associated with Susanoo’s palace. The shrine was originally called Suga-no-miya and served as the paramount Susanoo shrine in Izumo Province before Yaegaki Shrine rose to prominence. The current main hall dates to 1667, rebuilt after fire, but follows the architectural plan of much earlier structures. The shrine grounds occupy the traditional site of “Suga Palace” (Suga-no-miya), referenced in the Fudoki of Izumo Province compiled in 733 CE.

Susanoo no Mikoto is the primary deity, the storm god and younger brother of Amaterasu who was banished from heaven for his violent behavior but redeemed himself in Izumo by slaying Yamata no Orochi and saving Kushinadahime. He is enshrined here specifically in his role as palace-builder and husband, not as destroyer. Kushinadahime no Mikoto, his bride and the daughter of an elderly couple terrorized by the serpent, is enshrined alongside him. The shrine also venerates Ōnamuchi no Mikoto (Ōkuninushi), their descendant who would go on to rule and develop the land of Izumo. Susanoo governs courage, protection from disaster, and the arts of poetry and civilization-building — the transformation from wild god to culture hero.

After Susanoo tricked and killed the eight-headed serpent by getting it drunk on sake, he discovered the legendary Kusanagi sword in one of its tails and claimed Kushinadahime as his bride. He searched Izumo for a suitable place to build their home and found this location, where clouds rose beautifully from the mountains. Upon completing the palace, he composed the poem: “Yakumo tatsu / Izumo yaegaki / tsuma-gomi ni / yaegaki tsukuru / sono yaegaki wo” (“Eight clouds rise / in Izumo, an eightfold fence / to keep my bride within / I build this eightfold fence / oh, that eightfold fence”). This was Japan’s first waka poem, establishing the 5-7-5-7-7 syllable pattern that would dominate Japanese poetry for millennia. The “eightfold fence” refers both to the rising clouds and to the protective walls of the palace, making the poem simultaneously a description of place and a vow of protection.

The shrine complex is modest and forested, built into the hillside in a manner that suggests the remnants of an ancient settlement rather than a monumental religious structure. The main hall (honden) follows the taisha-zukuri style native to Izumo, with massive pillars and a gabled roof. Behind the main hall stands the Oku-no-miya (inner shrine), marking what tradition identifies as the actual foundation stones of Susanoo’s palace. The “husband-and-wife cedar” (meoto-sugi) grows near the main hall — two massive trees whose trunks have fused together, symbolizing the union of Susanoo and Kushinadahime. A stone monument inscribed with Susanoo’s poem stands in the precincts. The shrine is surrounded by dense forest, much of it old-growth cedar, preserving the atmosphere of ancient Izumo.

• Reitaisai (Autumn Grand Festival, October 6) — The main annual festival celebrating Susanoo’s arrival in Izumo, featuring kagura dance performances that reenact the Orochi legend and traditional offerings of sake, the weapon used against the serpent.
• Poetry Dedication Ceremony (May 3) — Poets gather to compose and dedicate verses at the birthplace of Japanese poetry, continuing Susanoo’s literary tradition.
• Meoto-sugi Blessing (year-round) — Couples visit the fused cedar trees to pray for marital harmony and enduring love, tying ema plaques to the surrounding fence.

Early autumn, particularly late September through October, when the surrounding mountains display fall colors and the air carries the first hint of winter storms — the season when clouds truly do rise in eightfold layers over Izumo. The Reitaisai in early October offers a chance to witness kagura in its home region. Spring brings fresh green to the ancient cedars, but the shrine is most atmospheric in autumn and winter when mist gathers in the valleys and the mythological past feels closest.
