藩政中期に於ける海部川流域の開拓過程—阿土兩國間の人口移動—

抄録

The writer researched the reclamation process of the valley by the records written in feudal days and are preserved in the village offices. The records are named munatsukecho (cencus registers) and Kenchicho (terriers).
1). The lower part of the valley was colonized earlier, being the southern frontiers of the domain of local clan, but the middle and upper parts were reclaimed later on account of their narrowness and remoteness of the valley. The reclamations were active in three periods, namely 1670 (Kammon), 1690 (Genroku), and 1708 (Hoei). There were intervals of about twelve years in between, and the colonization progressed gradually from lower to upper valley.
2). Several years preceding the progress of the each reclamation, there entered many people from the other districts. For example the village of Aikawa was reclaimed at the beginning of Hoei, and several years before the time, a dozen houses moved thither, chiefly from Tosa. Namely the reclamation was achieved by means of these immigrated men and women.
3) Tomoura and Okuura, were located at the entry of the Kaifu river, and the former a fishing village and the latter commercial centre of the districts. They accepted many immigrants from adjacent districts, not to speak of Tosa. They, however, earned their living mainly by fishing and commerce, and did not need so much arable lands, therefore the reclamation did not progress so much as the upper parts of the river.
4). The nativeplaces of immigrants from Tosa were mostly Kannoura, None, and the western part of Muroto Peninsular.
