Town Overview and Geography
Ishii has close economic and social ties with neighboring Tokushima City. Mergers between the two municipalities have been considered several times, although no merger has taken place. The northern part of the town borders the Yoshino River, which flows from east to west, while the Iino River, one of its tributaries, meanders through the central area.
Much of Ishii consists of flat land, making it suitable for agriculture and residential development. Small mountain ranges rise near the southern edge of the town, providing a contrasting natural landscape. The Yoshino River, often called “Shikoku Saburo,” is one of the region’s major waterways and an important symbol of its abundant water resources.
Area and Population
Ishii covers approximately 28.83 square kilometers. Its population was about 24,833 in 2020. Its proximity to Tokushima City has made the town an attractive place to live, and its population grew for several decades as residential development expanded. In recent years, however, the population has gradually declined, with the decrease among younger generations becoming a concern.
Population Changes
In 1970, Ishii had a population of 21,219. The figure rose steadily over the following decades, reaching 26,023 in 2000, before falling to 24,833 in 2020. These changes reflect broader demographic trends affecting many communities in Japan, particularly the aging population and the declining number of younger residents.

The History of Ishii Town
Ishii has a long history shaped by its agricultural setting, transportation links, and cultural institutions. In 1914, the Dogakuji-goe Tunnel was completed, improving passage through the area. Shimoura Station opened in 1934, further contributing to local transportation.
In 1950, Emperor Showa visited Ishii Elementary School during his postwar imperial tour of Japan. This visit is remembered as an important event in the town’s modern history.
The town’s past also includes difficult episodes. In 1955, the Morinaga arsenic milk poisoning incident became one of Japan’s major postwar public health tragedies. The incident involved powdered milk contaminated with arsenic and caused serious harm to infants and young children across the country.
In 1976, the Tanaka Family Residence received national cultural property designation, recognizing the historical value of the building and helping preserve the region’s architectural heritage.
Agriculture, Industry, and Local Economy
Agriculture remains a major part of Ishii’s economy, supported by the fertile plains and water resources of the Yoshino River basin. At the same time, the town has developed an industrial sector that provides employment and contributes to its modern economic life.
From the 1970s onward, food-processing companies established operations in the area. The Tokushima Plant of Nippon Ham began operating in 1974, followed by Japan Food Packers Shikoku in 1979. These developments helped expand the town’s industrial base alongside its traditional agricultural activities.
This balance between farming, manufacturing, and residential development reflects Ishii’s close relationship with Tokushima City while preserving its own local character.
