The Production of Japanese Agar and Gelatin in Edo Period

笔者在琼脂和明胶生产地考察了伊豆地区和大阪北部地区，考察了德川时代琼脂和明胶生产结构。伊豆的琼脂购买被称为urauke的渔场用途垄断，原材料和琼脂价格上涨，因为基蜀封建氏族介入那里。由于琼脂价格的显著上涨抑制了琼脂生产人同伴的经营，各封建宗族又强化了琼脂的垄断制度，发生了直生产中心村之间的对立和村中农民之间的冲突。

I took up Izu area and northern Osaka area at the agar and gelatin production place, and this study examined production structure of agar and gelatin in Tokugawa Era. The purchase of the agar in Izu was monopolized by fishing ground usage called urauke, and raw materials and a price of the agar that it was rose because Kishu feudal clan intervened there. Because the remarkable rise of the agar price suppresses the management of the agar production person companion, and each feudal clan strengthened a monopoly system of the agar again, the opposition between the villages of the straight production center and the conflict between the farmers in the village occurred.
