Complete Guide to Mikazuki Jinya (Sayo-cho, Hyogo Prefecture) | Detailed Explanation of History, Highlights, Access, and Restored Facilities
Located in Sayo-cho, Sayo-gun, Hyogo Prefecture, Mikazuki Jinya is a historical building that functioned as the administrative center of the Harima Mikazuki Domain from the mid-Edo period until the Meiji Restoration. Also known as “Noino Jinya,” it is currently undergoing restoration based on archaeological excavations and is attracting attention as a valuable example of Jinya architecture in the Harima region. This article provides a detailed explanation of Mikazuki Jinya, from its origins to its current highlights.
History and Background of Mikazuki Jinya
Dispossession of the Mori Family of Tsuyama Domain and Establishment of a New Domain
The history of Mikazuki Jinya begins with the dispossession of the Mori family of Tsuyama Domain in 1697 (Genroku 10). The Mori family of the Tsuyama Domain, which ruled Mimasaka Province (present-day Okayama Prefecture), became extinct when the fourth lord, Mori Nagashige, died without an heir. While the main branch of the Mori family was dissolved as a result of this confiscation, Mori Nagatoshi, the lord of the Tsuyama Shinden Domain in Mimasaka Province and a branch family member, was granted new territory.
Mori Nagatoshi was transferred to a territory encompassing 65 villages across the Sayo, Ibeshi, and Shiso districts of Harima Province, totaling 15,000 koku. This established the Harima Mikazuki Domain, and Nagatoshi became its first lord, establishing a jinya (fortified residence) in Mikazuki.
Construction and Completion of the Jinya
In Genroku 11 (1698), Mori Nagatoshi entered his new territory and began construction of the jinya, which would serve as the domain’s administrative center, and the residences of his retainers. Noinomura village was chosen as the site for the construction of the Jinya (fortified residence). The existing village headman’s residence was relocated there, and construction of the Jinya proceeded.
Construction of the Jinya took approximately two years, and it was largely completed by 1700 (Genroku 13). The Jinya measured approximately 51 meters east-west and 61 meters north-south, built on a hilltop castle-like location at an elevation of approximately 250 meters. Equipped with stone walls and moats, it possessed castle-like defensive functions despite its small size.
174 Years Until the Meiji Restoration
The Mikazuki Jinya was ruled by the Mori family for nine generations, starting with the first Mori Nagatoshi. Throughout the feudal period, the Noino district flourished as a castle town and a political and cultural center, becoming one of the important bases in the Harima region.
During the reign of the last lord, Mori Toshiakira, the Meiji Restoration occurred, and the Mikazuki Domain was abolished in 1871 with the abolition of the feudal domains and establishment of prefectures. While most of the jinya (fortified residence) was dismantled, a watchtower and part of the domain school remain, preserving them as valuable Edo-period architectural relics.
Architectural Structure and Characteristics of the Mikazuki Jinya
Basic Structure of the Jinya
The Mikazuki Jinya possesses the typical characteristics of Edo-period jinya architecture. Unlike castles, it lacked large-scale defensive structures such as a keep, but it had basic defensive features such as stone walls, moats, gates, and watchtowers.
The jinya grounds mainly consisted of the lord’s residence (“Goten”), the administrative office (“Seichou”), and the offices of retainers. A moat surrounded the area, and entry and exit were controlled by multiple gates.
Watchtower (Existing Structure)
The most important existing structure at Mikazuki Jinya is the watchtower. This watchtower is a valuable building that has survived from the Edo period and served the role of defense and surveillance for the Jinya. Its two-story structure, high enough to overlook the surrounding area, made it a crucial point for the overall security of the Jinya.
The watchtower exhibits a typical style of wooden architecture and is preserved as an important cultural asset that conveys Edo period architectural techniques. It can still be seen today, conveying the atmosphere of the Jinya at that time to visitors.
Structure of Stone Walls and Moat
Excavation surveys that began in 1996 revealed the detailed structure of the stone walls and moat of Mikazuki Jinya. The stone walls were constructed using the Nozurazumi technique, where natural stones were stacked, and were built using stone materials from the Harima region.
The moat was positioned to surround the Jinya, serving both defensive and drainage functions. Archaeological excavations confirmed the depth and width of the moat, as well as the foundation structure of the stone walls. The current restoration and maintenance are based on these findings.
Restored Facilities and Highlights
Restoration of the Nagaya Gate
The Nagaya Gate, which adorns the entrance to the Mikazuki Jinya (fortified residence), is a structure restored based on archaeological excavations and records from ancient documents. A Nagaya Gate is a type of gate with long buildings (retainers’ quarters and warehouses) on both sides, a common architectural style seen in samurai residences and fortified residences during the Edo period.
The restored Nagaya Gate faithfully reproduces the architectural techniques of the time, with details such as wood processing methods, joinery, and roofing techniques adhering to the Edo period style. Visitors can experience the atmosphere of an Edo-period fortified residence by passing through this gate.
General Gate and Middle Gate
The fortified residence had multiple gates, each used for different purposes. The Tsuyō-gomon (general gate) was used for everyday entry and exit, primarily by retainers and merchants. The Naka-gomon (middle gate), on the other hand, was a more formal gate, used for important guests and ceremonies.
These gates have also been restored through archaeological excavations, confirming the locations of their foundations and pillars. The arrangement and structure of the gates provide insights into the social hierarchy and rituals of the Edo period.
Bridges and Moat Landscape
Several bridges spanned the moat of the Edo residence. These bridges have also been restored, with wooden reconstructions being created. The combination of the moat and bridges demonstrates the defensive function of the residence while also forming a beautiful landscape.
The landscape, with its restored moat, bridges, and stone walls, is a valuable space that conveys the appearance of the Edo period residence and is a popular spot for photography.

Archaeological Findings and Historical Significance
Archaeological Excavations in the Heisei Period
Full-scale archaeological excavations of the Mikazuki Jinya began in 1996 (Heisei 8). These excavations revealed detailed structural information about the Jinya, including the building foundations, the structure of the stone walls, the layout of the moats, and drainage facilities.
Particularly important discoveries include the confirmation of the layout and scale of the palace buildings, the detailed understanding of the stone wall construction techniques, and the stratigraphic confirmation of the Jinya’s transformation process. These findings have greatly contributed to the study of Jinya architecture in the Harima region.

Culture and Education of the Mikazuki Domain
Domain School and Educational System
The Mikazuki Domain had a domain school for the education of the children of samurai. Parts of this school building still exist, conveying the state of education at the time. It is evident that even though it was a small domain, it placed great emphasis on education.
At the domain school, academic subjects, mainly Confucianism, were taught, and martial arts training was also conducted. Furthermore, efforts were made to cultivate practical administrative skills, fostering personnel who would support the domain’s administration.
Cultural Activities
