Kitadate Ozeki.

Kitadate Ozeki is a water conveyance system that stretches across the Shonai region, carrying water from a distant source to multiple communities. The structure consists of channels, sections of piping, and supporting infrastructure designed to move water efficiently across varied terrain.

Construction began in the mid-17th century under the Tokugawa shogunate as a major public project to improve water supply across the region. Thousands of workers participated in the effort, which became one of the largest infrastructure undertakings of the era.

The waterway carries the name of the family who engineered it, and their accomplishment remains central to how local people understand their region's development. Walking along it today, visitors encounter a reminder of human effort that shaped daily life for generations.

The system remains operational and continues to serve communities for agricultural and household water needs. Visitors can explore different segments, and understanding the terrain helps clarify how water traveled across such distances.

The system was completed with remarkable speed, reflecting the skill and coordination of the builders involved. This rapid execution was extraordinary for a project of its scale during that period.
