Origins in the Warring States Period
The history of Inariyama reaches back to the turbulent Sengoku period. In 1582, Uesugi Kagekatsu ordered the construction of Inariyama Castle. One of its purposes was to prevent the commander of Arato Castle from switching allegiance to the Tokugawa side.
The development of the castle was accompanied by the organization of the town and the establishment of the tenma system, a transportation system in which horses and porters were provided for official travel. These developments laid the foundations for Inariyama’s later role as a post town.
There is also a local legend concerning the origin of the place name. According to the story, a white fox disappeared into Yunosakiyama, leaving behind a mysterious connection between the landscape and the name Inariyama.
The Name Inariyama in Historical Records
The place name Inariyama appears in historical records at least as early as 1484, when a poem referring to “Inariyama” was recorded in a document from the Muromachi period.
This indicates that the name was already in use well before the formal development of the Edo-period post town. The presence of a place name called Umadashi-koji, or “Horse Exit Alley,” is also noteworthy. The term reflects the military planning techniques associated with the Takeda school of castle construction and has led to the possibility that the area once came under the influence of the Takeda clan.
Development as a Post Town
Inariyama had already begun functioning as a post town during the Keicho era, from 1596 to 1615. In 1614, when the Hokkoku West Road was formally developed, Inariyama was officially incorporated into the post-station system.
The town was initially organized into four neighborhoods: Shinmachi, Itsukamachi, Yokomachi and Yanagimachi. The names and organization of these districts changed over time as the town expanded.
Its strategic position along the highway quickly encouraged commercial activity. Merchants specializing in kimono fabrics, silk textiles and raw silk became particularly prominent, and Inariyama developed into one of the leading commercial centers of northern Shinano.
A Junction of Roads and People
Inariyama’s importance came not only from its role as a post station but also from its position at the junction of the Hokkoku West Road and Tani Kaido.
Travelers moving between different parts of Shinano passed through the town, while pilgrims heading toward Zenkoji contributed to a constant flow of people. Merchants, travelers and local residents gathered here, creating a lively environment in which commerce, information and culture could circulate.
One of the town’s traditional attractions was the Ku-sai-ichi, a periodic market held on nine designated market days. Such markets provided an important opportunity for merchants and residents to trade goods and helped establish Inariyama as a regional commercial center.
A Prosperous Center of Silk and Commerce
During the Edo period, Inariyama became particularly prosperous through the trade in silk textiles and raw silk. The town developed a reputation as one of the most important commercial centers in northern Shinano.
Merchant families, kimono wholesalers and other businesses lined the streets of the post town. Their prosperity contributed to the construction of substantial houses and storehouses, many of which were built to protect valuable merchandise.
The historic buildings that remain today provide a glimpse into this period of commercial success. Walking through the old streets, visitors can still see the distinctive architecture associated with prosperous merchant communities of premodern Japan.
The “Town of Storehouses”
Inariyama is now known for its traditional kura, or storehouses, and efforts have been made to preserve and revive the historic townscape as a “Town of Storehouses.”
The thick-walled kura were originally built to protect merchandise and valuables from fire, humidity and other dangers. Their white plaster walls and distinctive forms give the old streets a strong visual character.
For modern visitors, these buildings offer more than an attractive backdrop. They tell the story of the merchants who once drove the local economy and of the important role that Inariyama played in the regional transportation network.
Historic Buildings and Cultural Attractions
Several historic buildings and cultural facilities can be found around the center of Inariyama-juku.
Inariyama-juku Kurashikan
Inariyama-juku Kurashikan is one of the places where visitors can learn about the history and traditional architecture of the former post town. The facility helps preserve and introduce the atmosphere of the historic district and provides insight into the lives of local residents and merchants.
Yamatan
Yamatan, a former kimono merchant’s establishment, is another reminder of the commercial history of Inariyama. The building reflects the prosperity of the textile trade that once supported the town.
The Former Matsuki Family Honjin
The former Matsuki family Honjin marks another important aspect of the post town’s history. A honjin was a special lodging facility reserved primarily for feudal lords and other high-ranking travelers during the Edo period.
Such buildings were an essential part of the official post-station system and illustrate the social hierarchy and transportation system of early modern Japan.
Furusato Manga-kan
For a glimpse into a more recent aspect of local culture, visitors can stop at the Furusato Manga-kan. The facility exhibits works by Hideozo Kondo, a political cartoonist who was born in the local area.
The museum adds a cultural dimension to a visit, showing that Inariyama’s history extends beyond the Edo-period highway and merchant culture.
From Prosperity to Decline
The fortunes of Inariyama changed after the beginning of the Meiji period. Japan’s transportation networks and economic structure underwent major changes, and the traditional role of the post town gradually diminished.
The decline became particularly noticeable during the Showa Depression and the subsequent period of rapid urbanization. The construction of Inariyama Station on the outskirts of the historic town also shifted the focus of transportation away from the old center.
Ironically, the changes that reduced the commercial importance of the old town also helped preserve its historic character. Because modern development was concentrated elsewhere, many traditional buildings survived in the old district.
Walking Through the Old Town
Today, the best way to appreciate Inariyama-juku is simply to walk through its historic streets.
The old road, traditional merchant houses and kura storehouses create an atmosphere quite different from that of a modern Japanese city. Rather than being a single isolated monument, Inariyama is a historic townscape in which architecture, streets and local history come together.
Visitors interested in Japanese history can look closely at the buildings and imagine the merchants, pilgrims and travelers who once moved along the same streets.
Inariyama and the Zenkoji Pilgrimage Route
The connection with Zenkoji Temple is central to understanding the importance of Inariyama-juku.
For centuries, Zenkoji attracted pilgrims from across Japan. Roads leading toward the temple became important transportation routes, and post towns developed along them to provide accommodation, food, transportation and goods.
Inariyama benefited greatly from this movement of people. Its location on the Hokkoku West Road allowed it to function both as a place for travelers to rest and as a regional market where goods from surrounding areas could be exchanged.
Historic Sites Around Inariyama
The area around Inariyama-juku contains several other sites connected with the religious and cultural history of Chikuma.
Takemizuwake Shrine, also known as Hachiman Shrine, is one of the important historic shrines in the surrounding area. Its long history and connection with local religious traditions provide a natural complement to a visit to the old post town.
Hasedera Temple, known as one of the most important Hasedera temples in northern Shinano, is another notable destination nearby. Visiting these sites together makes it possible to explore the wider religious and cultural landscape that developed around the historic roads of Chikuma.
Access to Inariyama-juku
Inariyama-juku is approximately a 20-minute walk from JR Inariyama Station on the Shinonoi Line.
For travelers arriving by car, the area is also conveniently accessible from the Koshoku Interchange on the Nagano Expressway.
Because the historic district is compact enough to explore on foot, visitors can combine a walk through the old post town with nearby temples, shrines and other historic sites.
A Journey into Old Shinano
Inariyama-juku is a place where the commercial, transportation and cultural history of old Shinano can still be experienced through the townscape itself.
The historic road, merchant houses, white-plastered storehouses and former lodging facilities reveal the prosperity of a town that once stood at a major crossroads. Its connection with the Zenkoji pilgrimage route and the silk trade explains why Inariyama grew into such an important center of northern Shinano.
Although its role as a post town eventually declined with the modernization of transportation, the old district retained many of the buildings and streets that give it its distinctive character today.
Experience the Historic Streets of Inariyama
A visit to Inariyama-juku is an opportunity to step away from modern Japan and explore a quieter side of Nagano’s history. Strolling along the former highway, admiring the traditional kura storehouses and discovering the stories of merchants, pilgrims and travelers allows the past to emerge naturally from the streetscape.
For travelers exploring Chikuma City, Inariyama is especially rewarding because it brings together the history of the Hokkoku West Road, Zenkoji pilgrimage culture, silk commerce, traditional architecture and local cultural heritage in one atmospheric historic district.
