The Morioka han (盛岡藩) encompassed part of present-day Iwate & Aomori Prefectures. It was governed by the Nambu, a tozama daimyo (outsider lord), who eventually sided with Ieyasu in Sekigahara. They governed throughout the Edo period. In the Boshin War, the Nambu initially sided with the Shogun, only later to shift over to the Meiji Emperor's side.
The following lineage, which follows a 3rd generation branch under Ota Harubei, was listed as entering Morioka-han in 1855, under Ueno Uemon Kiyomasa (上野右衛門清正), a 12th generation shihan. According to an informant, the ryu was listed in a study by the Morioka City Library as Araki-ryu kenjutsu (荒木流剣術). If this is correct, then Morioka-han Araki-ryu, much like Annaka-han Araki-ryu, was somewhat different from the original school.
Nothing is known about previous generations of this line, nor are there any available records of its curriculum or subsequent role in Morioka.
