Formative Process of Regional Concentration in a JapaneseWhaling Fishing Ground in the Edo Period : Analysis of the Particularity of the SaikaiWhaling Industry Area

The whaling industry in early modern Japan was the greatest fishery in Edo period. At the time, whaling was mainly conducted in four districts (i.e. Kishu, Tosa, Tyosyu, and Saikai). whaling industry was carried on by large−scaled industrial management object which was called “whaling organization (kujira−gumi)”. I have for my object to make the regional concentration process of the whaling fishing ground in Goto Han clear about a whaling industry in Goto Han who didn’t also aim so much in the Saikai area this time. That was separated 3 periods in an extended period from Enpo and a Genroku period to Bunsei and a Tenpo period here in particular, and a change and the development process of the “whaling organization (kujira−gumi)” in Goto Han were considered, also considering a relation with a financial problem of Goto Han. When saying a whaling industry in Saikai area in the Edo Period up to now, I was very strong in an image of an achievement of Fukazawagumi of Omura han and a big “whaling organization (kujira−gumi)” of 3, Nakao, Doi and Mastomi. On the other hand, activity of the Eguchi family of Arikawa village was learned about in Goto Han, too. But development of the “whaling organization (kujira−gumi)” of the former and the latter has been talked on separately without associating. But, the Saikai area “whaling organization (kujira−gumi)”which can have talked on individual “whaling organization (kujira−gumi)” management and its development process independently respectively up to now was intermingled in a whaling fishing ground of Goto Han actually by this analysis. Moreover it was revealed that habitat segregation was done by a fishing ground as for the latter period in the Edo Period. And when it was considered from a geographical side, regional centralization in a whaling fishing ground in Nishiumi area was seen, and moreover it was revealed that a differentiation phenomenon in a winter fishing ground and a fishing ground in spring has formed. It’s understood to be different from a whaling industry area of 3, other Kishu, Tosa and Nagasu from the thing.In other words, it was being enabled that management activity in fishing ground area of sea of a whaling industry in this Saikai area is formed beyond the Han. Development of a whaling industry management was seen aggressively in the the inter−han whaling industry which is the characteristic of the Saikai whaling industry area here. That led to successive development by the “whaling organization (kujira−gumi)” from formation in the first term in the Edo Period in this whaling industry area to the latter period. Above, the geographical angle as well as the historical science−like angle of the ancient document emphasis were taken in by the main subject. And I made it clear about formative process in a whaling industry area in Japan in the Edo Period when I had almost no studies up to now by that. Moreover the local industry as a large− scale whaling industry and concerning in Han fief were made clear
