The History of the Former Yakage Honjin
The Development of Yakage-juku
Yakage-juku flourished as a post town along the Sanyōdō, an important highway connecting western Japan. Following the Battle of Sekigahara in 1600, Kobori Shinsuke received a fief of 10,000 koku in Bitchū Province and became responsible for governing the area. His son, Masakazu, better known as Kobori Enshū, inherited the domain and contributed to the development of Yakage Village.
As the sankin-kōtai system became established during the Edo period, Yakage developed an important role in accommodating traveling lords and their entourages. Its location along a major route made it a significant stop for official processions and other travelers.
The Ishii Family and Its Role as Honjin Keepers
The Ishii family moved to its present location in 1620, during the Genna era. When the sankin-kōtai system was formally established in 1635, the family was appointed to operate the honjin. The Ishii family continued in this role for generations while also running a sake brewery, which contributed to its prosperity.
The family’s commercial name was Sadoya. Its ancestry is said to trace back to a family that served Mōri Motokiyo toward the end of the Sengoku period, an era marked by political conflict and the struggle for regional power.
Architecture and Facilities
Traditional Buildings Preserved Through the Centuries
Numerous historic structures remain on the property, including the distinguished entrance gate, the raised-status reception room known as the jōdan-no-ma, a rear gate, a western storehouse, and sake storehouses. Many of these buildings were reconstructed between the middle and late Edo periods and have survived with remarkably few alterations.
One of the most notable features is the Onari-mon, the formal gate used by feudal lords and officials of the shogunate. Rebuilt in 1832, it has double-opening doors made from single slabs of Japanese zelkova wood. Its impressive construction reflects the status of the guests who once entered through it.
Reception Rooms and Brewing Facilities
The residence includes formal reception facilities designed to welcome high-ranking visitors. The jōdan-no-ma and the Onari-mon formed part of the setting in which feudal lords could rest or stay overnight during their journeys. These spaces preserve the atmosphere of an official inn from the Edo period.
The grounds also contain the main residence and several storage buildings associated with the family’s sake-brewing business, including inner and western storehouses, a rice storehouse, and sake storehouses. Together, the buildings illustrate how the Ishii family combined its official duties as honjin keepers with a successful commercial enterprise.
Designation as an Important Cultural Property
In 1969, the main residence, Onari-mon, and other historic structures at the Former Yakage Honjin were designated Important Cultural Properties of Japan. The designation recognizes both the architectural quality of the buildings and their historical significance as an official inn along one of the country’s major highways.
In 1983, the designation was expanded to include the residential land and additional properties, such as the retirement residence and a traditional architectural site plan. These protections help preserve the historic layout and the architectural details that reveal how the honjin operated.
Historical Records and Distinguished Guests
Records of Atsuhime’s Stay
The Ishii family has preserved numerous historical documents concerning travel and transportation during the Edo period. Among them is a record of Atsuhime, later known as Tenshōin, staying at the Yakage Honjin while traveling from Satsuma to marry Tokugawa Iesada, the 13th shogun of the Tokugawa shogunate.
This record provides a vivid example of the importance of Yakage-juku as a stopping point for prominent travelers. It also offers valuable evidence of the journeys undertaken by members of the ruling elite during the Edo period.
Feudal Lords and Literary Figures
Many other notable figures stayed at the Ishii residence. Mōri Daizen-no-taifu Takachika, a feudal lord from the Chōshū domain, reportedly visited the honjin 21 times and stayed overnight on 19 of those occasions. Other prominent guests included Abe Ise-no-kami Masahiro and Matsudaira Satsuma-no-kami Nariakira.
The residence also welcomed distinguished scholars and literary figures, including Rai San’yō and Rai Kyōhei, who left poems associated with their visits. These connections add another layer to the site’s historical significance, revealing the role of post towns as places where political figures, travelers, and intellectuals crossed paths.
