The Yoshioka family, together with the Goto family, is a prestigious family
that prospered throughout the Edo period as a metal worker of the Tokugawa Shogunate.
Founded by Bungo no suke Shigetsugu, he came to the attention of Ieyasu
in Kyoto around the Keicho era and went down to Edo at his invitation.
The family prospered until the end of time, with different lines and sects,
but the name Inba no suke belonged to the main family,
and no one other than the main family was allowed to use it.
