Ichinomiya: The Historical Hierarchy of Japan's Provincial Shrines
In the rich tapestry of Japanese spiritual history, the term Ichinomiya (一宮) holds a position of significant prestige. Literally translating to "first shrine," it refers to the highest-ranking Shinto shrine within a specific province. This hierarchical system extended beyond the first, designating subsequent shrines as ninomiya (second), sannomiya (third), shinomiya (fourth), and so forth.
This historical classification has left a lasting mark on Japan's geography. For instance, the modern city of Ichinomiya in Aichi Prefecture derives its name from the Masumida Shrine, which served as the Ichinomiya for the former Owari Province.
Key Facts
- Ichinomiya denotes the highest-ranking shrine in a Japanese province.
- The ranking system follows a numerical order: Ichinomiya (1st), Ninomiya (2nd), Sannomiya (3rd), etc.
- Most Ichinomiya shrines are ancient and are documented in the Engishiki, a collection of laws and regulations completed in 927 AD.
- The ranking was often tied to the Ritsuryō system, where imperial governors (kokushi) would visit the Ichinomiya first to announce their appointment to local deities.
- While many Ichinomiya are major shrines, being the "first" does not strictly guarantee a shrine is the largest or oldest in the province.
The Origins of the Ranking System
While the concept of the Ichinomiya is widely recognized, there is no surviving documentary evidence that explicitly dictates exactly how these shrines were ranked or precisely when the system was established. However, a common thread among these shrines is their antiquity; most are listed in the Engishiki records from the early 10th century.
The designation was deeply intertwined with the Ritsuryō system—the legal and administrative framework established during the Nara period. Under this system, kokushi (imperial governors) were dispatched to various provinces. Upon arriving at their provincial capital from Heian-kyo (modern-day Kyoto), the governor's first official act was to visit the Ichinomiya. This visit served to formally announce the governor's appointment to the local kami (deities). Consequently, these shrines were typically located near the provincial capital and dedicated to significant local deities.
Even after the Ritsuryō system declined during the Kamakura period, the prestige of the Ichinomiya remained. In many cases, even when the original provincial capitals fell into ruin and their locations were forgotten, the title "Ichinomiya" survived as a permanent place name.
The Popularization of Pilgrimages
The cultural importance of these shrines grew significantly during the Edo Period. A Shinto scholar named Tachibana Mitsuyoshi spent 23 years, beginning in 1675, traveling to Ichinomiya across the nation. His 13-volume travelogue helped popularize pilgrimages to these sacred sites among the general public.
Rivalries and Ambiguities in Designation
Although a province is theoretically supposed to have only one "first shrine," historical complexities often led to rival claimants. Several factors contributed to this ambiguity:
- Relocation of Capitals: If a provincial capital moved, a different shrine might be designated as the new Ichinomiya.
- Provincial Mergers: When two provinces merged, the new entity might end up with two different Ichinomiya.
- Conflicting Records: Ambiguous ancient documentation and varying historical criteria often allowed multiple shrines to claim the top rank.

Frequently Asked Questions
Is the Ichinomiya always the largest shrine in the province?
No. The designation of Ichinomiya is based on historical administrative importance and its role in the provincial government's ritual duties, rather than strictly on the physical size or age of the shrine.
What is the difference between Ichinomiya and Myojin Taisha?
While many Ichinomiya are classified as Myojin Taisha (highly important shrines), the terms refer to different things. Ichinomiya is a provincial ranking, whereas Myojin Taisha refers to the perceived importance and status of the deity and the shrine itself.
Why are there sometimes multiple Ichinomiya in one area?
This usually occurs due to historical shifts such as the relocation of provincial capitals, the merging of two provinces, or conflicting ancient records that create rival claims to the title.
Does the modern ranking system still use the Ichinomiya concept?
While the Ichinomiya was a historical administrative designation, many of these shrines were later accorded high ranks under the modern system of ranked Shinto shrines.
What was the role of the Engishiki in this system?
The Engishiki was a set of official records completed in 927 AD. It serves as a vital historical document because most shrines designated as Ichinomiya are listed within its pages, confirming their ancient status.
