The origins of the city of Tsubame, located in Niigata Prefecture, Japan, are closely tied to the struggle between man and nature. Originally a small agricultural settlement, its life depended on the high waters of the Shinano River.
Geography was the key factor in the city's formation. Frequent flooding made rice cultivation a risky endeavor, forcing local residents to seek alternative sources of income. In the early Edo period (17th century), blacksmithing began to take root here. At the initiative of local authorities, masters were invited from Edo (modern-day Tokyo) to teach farmers how to make wakugi—traditional Japanese hand-forged nails.
The settlement's commercial significance grew thanks to river transport, which allowed finished metal products to be sent to the country's major cultural centers. Thus, by the 18th century, a unique economic model based on artistic metalworking had formed in Tsubame, eventually transforming the city into one of Japan's primary craft hubs.
