Yamaoka Tesshū wasn’t from a han, so there is no domain school to consult for his early training. Yamaoka was instead a bakufu hatamoto, twice over.
He was born in 1836 in Edo as a son of Ono Asaemon Takafusa, a granary commissioner (kura-bugyō) and a roughly 600-koku hatamoto. Tesshū’s mother came from a Kashima Jingū priestly family, the Tsukahara, counting Tsukahara Bokuden among her forebears — so the Kashima sword lineage brushes his maternal line even though his own arts were the Yamaoka Jitokuin-ryū spear and, later, his Ittō-derived Mutō-ryū.
In 1845 his father was made Hida gundai and the boy spent his youth in Hida-Takayama, which matters here: Hida was tenryō — directly bakufu-administered land of some 114,000 koku under a gundai — not a daimyō’s domain. And the house he later married into was no different: the Yamaoka were a small-stipend hatamoto family of 100 bales and five rations, into which he was adopted in 1868 after marrying Fusako, the sister of the spearman Yamaoka Seizan. So at every turn — birth family, formative locale, adoptive family — he sits inside the direct shogunal retainer world, not a han
