The Seieitai (精鋭隊; select or elite corps) was an elite bakufu bodyguard corps raised at the very end of the Tokugawa period specifically to protect the last shogun, Tokugawa Yoshinobu.
It was a hand-picked bodyguard for Yoshinobu (Katsu Kaishū’s selection, under Chūjō as the foremost swordsman of the day), drawn from skilled bakushin and Kōbusho men, and later reconstituted as the Shinbangumi (新番組). It belongs to a tier the Keiō reforms deliberately created. When Yoshinobu’s reforms from 1866 dissolved or shrank the old-style organizations such as the Ōban, the ablest of the surplus personnel were folded into the army as units of praetorian character (親衛隊的な性格): the Okuzume-jūtai (奥詰銃隊) and the Yūgekitai (遊撃隊, the successor to the okuzume inner guard). The Seieitai is of that same family: a guard close to the shogun’s person, formed from thebest of the dissolved guards plus the old Kōbusho academy’s sword and spear masters. The academy was effectively the recruiting pool for this guard tier, which is why the same handful of names keeps reappearing in the units’ rosters..
After Yoshinobu’s Taisei Hōkan (大政奉還, return of governing authority to the throne) in Keiō 3 (1867), Katsu Kaishū and others, fearing for Yoshinobu’s safety, organized the Seieitai to guard him, and Chūjō Kinnosuke Kageaki was selected as its head as the foremost swordsman of the day. It was a hand-picked unit of skilled bakufu retainers,
Chūjō Kinnosuke Kageaki (中條金之助景昭, 1827–1896) was the son of a koshōgumi hatamoto, trained in Yamaga-ryū, Shingyōtō-ryū and Hokushin Ittō-ryū, served the 13th shogun Tokugawa Iesada rom Kaei 7 (1854) as a household martial-arts attendant (kenjutsu/jūjutsu sewa-kokoroe).
He became a kenjutsu kyōjukata at the Kōbusho after it opened, associated with its Shingyōtō-ryū (心形刀流) contingent. At that time at the Kōbusho, the 9th-generation Iba Hidetoshi was kenjutsu shihan-yaku, and from this school Mitsuhashi Torazō, Chūjō Kinnosuke (Kageaki), and Minato Shinpachirō became kenjutsu kyōjukata, forming a major bloc there.
In Bunkyū 2 (1862) he became a superintendent of the Rōshigumi alongside Yamaoka Tesshū, and afterward held oversight posts over the Shinchōgumi.
Chūjō studied Totsuka-ha Yōshin-ryū under Totsuka Hikosuke. That shared Totsuka/Yōshin-ryū lineage is a plausible reason Matsuoka ended up assigned under Chūjō in the Seieitai in 1867, beyond their both being bakushin swordsmen.
When Yoshinobu withdrew from Edo, his escort to Mito in the fourth month of 1868 was provided by Seieitai and Yūgekitai men, among them Chūjō Kageaki and Takahashi Deishū. The unit then accompanied the Tokugawa house to Sunpu (駿府, modern Shizuoka).
Chūjō led the Seieitai — later the Shinbangumi (新番組) — and their families, some two hundred people, to Sunpu; one account puts the escorting “bakufu elite” at around three hundred.
Having lost their stipends and status with the Restoration, the corps famously became the pioneers of the Makinohara tea plantation: Chūjō Kageaki, following Yoshinobu to Sunpu, resolved together with the guard corps to develop the then-bakufu land of Makinohara, beginning in Meiji 2 (1869) on some 1,400 hectares — trading the sword for the hoe, eventually turning the barren upland into a tea garden of over 5,000 hectares, on the proposal of Yamaoka Tesshū and Katsu Kaishū.
