盛岡藩
In 1664, the 20,000 "koku" Hachinohe Domain was split from Morioka Domain as a nominally subsidiary domain. However, relations between Morioka and Hachinohe were often strained and Hachinohe was considered independent, rather than a subsidiary. Morioka Domain was thus reduced to 80,000 "koku", but was able to develop new rice lands, and reverted to 100,000 "koku" status in 1683. The 5th "daimyō", Nanbu Yukinobu, reduced the domain to 92,000 "koku" by setting up his two younger brothers as "hatamoto" with 5000 "koku" and 3000 "koku" each.
