Abstract
The authors studied Fujiwara's water-wheels for irrigation which were built at Kazusa region in Chiba prefecture. They surveyed literature on bucket chain conveyor system for water in the Edo period. There were 3 materials concerned with Fujiwara's water-wheel. The authors restored Fujiwara's water-wheel bucket which was drawn on the Report of Archaeological Investigation carried out the Fujiwara-Type scoop wheel, No. 1 and 2 in Yoro, Ichihara city, Chiba prefecture. They compared data of Fujiwara's water-wheel bucket restored with data of literature for Fujiwara's water-wheel. Fujiwara's water-wheel power was calculated from data of the bucket restored.
