Abstract
At the foot of Mt. Hakusan, farmers seasonally moved between the parent village in the valley where they spent the winter and the mountainside fields where they engaged in slush-and-burn farming and sericulture. Firearms were widely used to protect crops from wild boars. The parent village was unusually large considering local geographic conditions. When an insurrection was suppressed in 1582, those who escaped presumably introduced firearms among mountain villagers. Kato Tobei, a local medieval clan, constructed waterworks, which apparently contributed to the formation of large parent village in the Tedori Valley. These are new interpretation I presented in this study.
