This article comprehensively explains everything you need to know before visiting Aoi Aso Shrine, from its history and the highlights of its buildings to its annual festival, the Okunchi Festival, and access information.
History and Origins of Aoi Aso Shrine
Circumstances of Founding
Aoi Aso Shrine is said to have been founded on September 9th, 806 (Daido 1), during the Choyo Festival. It was established by inviting a divided spirit from Aso Shrine, located in Ichinomiya-machi, Aso City, and praying for the development and prosperity of the Hitoyoshi-Kuma region.
Of the twelve deities enshrined at Aso Shrine, the main deity is Takeiwatatsu-no-Mikoto, the grandson of Emperor Jimmu, the first emperor of Japan. The shrine also enshrines his consort, Asotsuhime-no-Mikoto, and their two children, Kuninomiyatsukohayamikatama-no-Mikoto.
Takeiwatatsu-no-Mikoto is known as the god who pioneered the vast plains of Aso, and it is believed that the shrine was established to pray for the safe progress of development in the Hitoyoshi-Kuma region.
Deep Connection with the Sagara Clan
From the medieval period onward, Aoi Aso Shrine received deep reverence from the Sagara clan, who ruled Hitoyoshi. Through the protection of successive Sagara clans, it established its position as the principal guardian shrine of the Hitoyoshi-Kuma region.
The current shrine building was constructed between 1610 (Keicho 15) and 1613 (Keicho 18) during the early Edo period by Sagara Nagatsune (Yorifusa), the feudal lord at the time. One ridge beam inscription from this construction, along with five inscribed plaques detailing the dates and contents of renovations, are designated as National Treasures.
Former Shrine Rank and Current Status
Under the modern shrine ranking system of the Meiji era, it was ranked as a prefectural shrine, and is currently a special shrine of the Association of Shinto Shrines. As a center of faith in the Hitoyoshi-Kuma region, it continues to attract many worshippers.
Highlights of the National Treasure-Designated Buildings
The most striking feature of Aoi Aso Shrine is its group of five shrine buildings, all of which are designated as National Treasures. Arranged in a straight line from south to north, with the south side facing forward, each building possesses its own unique architectural style and beauty.
Romon (Gate Tower)
The imposing Romon, standing proudly at the entrance to the shrine grounds, is a two-story gate built in the authentic Zen Buddhist style. Its distinctive thatched roof and majestic appearance, primarily based on black lacquer, overwhelm visitors.
The exquisite details, such as the tsumegumi (bracket system) and katomado (flower-shaped windows), characteristic of Zen Buddhist architecture, make it a masterpiece showcasing the pinnacle of early Edo period architectural technology. It was the first thatched-roof shrine or temple building in Japan to be designated a National Treasure, and its historical value is immeasurable.
Haiden (Worship Hall)
The Haiden, which appears directly ahead after passing through the Romon, is where worshippers offer their prayers. The spacious area is covered by a thatched roof, and the black lacquered pillars and beams create a solemn atmosphere.
The main hall (Haiden) is a five-bay by three-bay hip-and-gable roof structure with a portico at the front. The interior ceilings and pillars are adorned with intricate decorations, showcasing the high level of skill of the craftsmen of that time.
Heiden (Offering Hall) and Corridor
The Heiden, connecting the Haiden and the Honden (main sanctuary), is an important space for performing Shinto rituals. The Corridor serves as a connecting walkway between the Heiden and the Honden, and these structures together create a unique spatial composition.
The Heiden features exquisite carvings and decorative metalwork throughout, and the meticulously crafted details captivate the viewer. While predominantly black lacquer, the gleam of the metalwork further enhances the solemnity.
Main Shrine (Honden)
Located at the innermost part of the shrine complex, the main shrine is the most sacred place where the enshrined deity resides. It is built in the Sangensha Nagare-zukuri style, with a thatched roof.
While the exterior of the main shrine is primarily black lacquer, the carvings on the frog-leg brackets (kaerumata) and wooden carvings (kibana) are simply magnificent. Dragons, lions, and floral and bird motifs are carved in three dimensions, showcasing the pinnacle of early Edo period carving techniques.
The metal fittings are also magnificent, with the gleaming gold ornaments standing out against the black lacquer background, conveying the shrine’s high status.
