Although the modern city of Miyoshi was officially formed in 2006 through the merger of several towns (Ikeda, Yamashiro, Mino, and others), the history of settlement in these lands dates back to ancient times. This region, located in the mountainous heart of Shikoku Island, has long played the role of an important strategic point. The area gained particular fame from the legendary Iya Valley, which in the 12th century became a refuge for samurai of the Taira (Heike) clan fleeing after their defeat in the Genpei War.
Key Factors of Formation
The formation and development of settlements in present-day Miyoshi were determined by several important factors:
Geographical Position: The district is historically called the "navel of Shikoku." The town of Ikeda served as a key transport hub where roads connecting the provinces of Awa, Tosa, Iyo, and Sanuki converged.
Yoshino River: The island's largest river allowed for the transportation of goods and the floating of timber, turning the region into an important trade corridor.
Natural Protection: Steep slopes and deep gorges (such as Oboke and Koboke) made the area difficult to access, allowing local residents to control the passes and maintain relative autonomy.
Early Cultural and Economic Features
The economy and culture of the region during the Edo and Meiji periods had very specific characteristics:
Tobacco Industry: Miyoshi became famous as one of Japan's leading centers for tobacco cultivation. The production and trade of tobacco generated significant income, contributing to the prosperity of local merchant families.
Unique Architecture: Thanks to the Taira clan refugees, unique vine suspension bridges (Kazurabashi) and traditional thatched-roof houses built on steep slopes have been preserved in the region.
Forestry: The abundance of forest resources allowed for the development of woodworking, which, along with tobacco farming, formed the basis of the residents' well-being.

Milestones
Stages of Development and Transformation of Miyoshi
The development of Miyoshi is a journey from scattered mountain settlements to an important administrative and tourist center of Tokushima Prefecture. Key stages in the city's formation are linked to the use of natural resources and its advantageous geographical position.
The Era of "Tobacco Wealth" (17th–20th Centuries)
The cultivation and processing of tobacco became the region's first powerful economic driver. This led to the formation of a wealthy merchant class in the Ikeda district. Significance for the city: the accumulated capital allowed for the construction of affluent quarters with traditional architecture, many of which, including houses with "udatsu" (firewalls), have survived to this day and define the historical look of the center.
Transformation into a Transport Hub (Early 20th Century)
The construction of railway lines and the opening of Awa-Ikeda Station made the city the main gateway to the mountainous part of Shikoku. Significance for the city: Miyoshi became a key transfer hub connecting the island's four prefectures, stimulating population growth, trade, and the development of the service sector.
Hydro-technical Revolution (1970s)
The construction of the Ikeda Dam on the Yoshino River radically changed the landscape and economy. Significance for the city: the dam not only provided flood control but also turned the city into a strategically important water supply facility for the entire island, earning it the unofficial nickname "Shikoku's Water Jug."
Administrative Consolidation (2006)
The merger of several towns and villages into the single city of Miyoshi united the urbanized center of Ikeda with the remote mountain regions of the Iya Valley. Significance for the city: this allowed for centralized resource management and the creation of a unified tourism brand combining historical heritage and wild nature.
Shift Towards Ecotourism and Sports (21st Century)
Hosting the World Rafting Championship (2017) and the recognition of the local farming system as a GIAHS heritage site (2018). Significance for the city: the economic focus shifted from industry to international tourism, turning Miyoshi into a global capital for water sports and a center for preserving unique agricultural traditions.
Architecture
Architectural Appearance and Urban Planning
Miyoshi's urban development is shaped by its complex mountainous terrain and its role as a transportation hub. The city does not have a single unified urban style; rather, it is a mosaic of merchant quarters in the valley and secluded settlements on steep slopes. The region's architecture reflects an adaptation to harsh natural conditions and the prosperity brought by the tobacco trade.
Architectural Styles and Historical Eras
Miyoshi's appearance is dominated by traditional Japanese styles typical of rural and merchant environments, which give way to the functionalism of modern infrastructure.
Vernacular Architecture — Kamakura, Muromachi, and Edo Periods
In the inaccessible Iya Valley, a unique style of mountain farmhouses has been preserved. These are massive wooden structures with thick thatched roofs (kayabuki), built on steep slopes using stonework to reinforce the foundation. The style was dictated by the need for protection against wind and heavy snowfall.
Merchant Style (Machiya) — Edo, Meiji, and Taisho Periods
In the Ikeda district, the center of the tobacco trade, a style of wealthy merchant houses emerged. A characteristic feature is the "udatsu"—protruding side firewalls under tiled roofs. Originally created for fire protection, they became a symbol of the owner's wealth and status, as their construction required significant funds.
Industrial Modernism — Showa Period (20th Century)
With the development of hydroelectric power and transportation, monumental concrete structures entered the city's landscape. The construction of dams and railway bridges across gorges introduced elements of functionalism, where engineering necessity dictated the form.
Iconic Architectural Sites and Districts
Several key areas define Miyoshi's appearance, each representing a specific stage in the city's history:
Honmachi Quarter (Udatsu Street)
A historical street in the Ikeda district where old mansions of tobacco magnates and sake producers are preserved. The buildings feature white plastered walls, dark wood, and elegant tiled roofs with udatsu elements. It is a living museum of Meiji-era commercial prosperity.
Ochiai Settlement
An area in the Iya Valley included in Japan's list of Important Preservation Districts for Groups of Traditional Buildings. Here, you can see a classic example of vertical village planning: houses with thatched and tin roofs cascade down the mountainside, connected by narrow winding paths and Edo-period stone walls.
Old Kimura Family Residence
A striking example of residential architecture from the Iya Valley dating back to the end of the Edo period (1699). It is the oldest house in the region, demonstrating the lifestyle of wealthy peasants of that era: an earthen floor, an open hearth (irori), and the absence of ceilings to allow smoke ventilation, which helped preserve the thatched roof.
Ikeda Dam
A massive hydraulic structure spanning the Yoshino River. Although it is a utilitarian facility, its scale and integration into the river landscape have become a symbol of the city's modern era, changing not only the geography but also the region's economy.
Notable People
Famous Natives and Historical Figures of Miyoshi
The history of Miyoshi is inextricably linked with the names of prominent military leaders, cultural figures, and athletes whose legacy has shaped the unique character of this mountainous region.
Miyoshi Nagayoshi (1522–1564) Role: Sengoku daimyo, head of the Miyoshi clan
One of the most powerful feudal lords in Sengoku-period Japan, who effectively ruled the Kinai capital region until the rise of Oda Nobunaga. Although his main political achievements were centered in the heart of the country, the roots of the Miyoshi clan trace back to the district of the same name in Awa Province (modern-day Miyoshi City). The city honors Nagayoshi as its historical patron and holds annual festival processions in his honor.
Taijiro Tamura (1911–1983) Role: Writer, novelist
A native of the Ikeda district who became an iconic figure in post-war Japanese literature. Tamura is considered the founder of the "literature of the flesh" (nikutai bungaku) genre, reflecting the realities and sensibilities of an era of change. His most famous novel, "Gate of Flesh," brought him national fame. A museum dedicated to his life and work has been established in Miyoshi.
The legendary coach of the Ikeda High School baseball team. Under his leadership, the team from a small mountain town achieved the impossible, winning the national Koshien championship multiple times in the 1980s. The "Ikeda Era" in school baseball made the city famous throughout the country. He is an honorary citizen of the city.
Born in the Yamashiro district, he dedicated his life to the study of Japanese folklore and yokai (supernatural creatures). It was his field research in his native mountains that introduced the legend of "Konaki-jiji" (the Old Man Who Cries Like a Baby) to the world. Thanks to his work, the Yamashiro area is now known as the "Yokai Village," attracting tourists with its mystical stories.
Shunichi Suzuki (1910–2010) Role: Politician, Governor of Tokyo
A well-known statesman who served as the Governor of Tokyo for 16 years. Although Suzuki was born in the capital, his father was from Ikeda, and the politician always maintained a close connection to his ancestral home. He contributed significantly to the cultural and economic development of the region, for which he was awarded the title of honorary citizen, and a memorial hall in his name was opened in the city.
