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.
