This paper examines the maintenance work of the Minuma Substitute Canal by the Meiji Government and how Noriyoshi Takao who lived at Senjū-nakagumi was involved in it. In the 1880s, when the cost of maintaining the Minuma Substitute Canal was shifted from government expenditures to private ones, the early modern water usage system was on the verge of being converted to a modern one. This meant that the system, which was based on villages or ryō (領), transformed into one based on individuals, especially landowners. The village served as a cost-sharing unit during the Meiji period. Ryō (領) were operated in the downstream water of the Minuma Substitute Canal where there were no critical structures. However, districts (郡) supervised the water usage of ryō, creating a multilayered local community in terms of water usage.
