Kyoto Shoshidai
Inaba Masamichi was the eldest son of the previous daimyō of Odawara, Inaba Masanori. Due to the influence of the "Tairō" Sakai Tadakiyo, he rose rapidly through the hierarchy of the Tokugawa shogunate. He was appointed concurrently as a "Sōshaban" (Master of Ceremonies) and "Jisha-bugyō" on April 9, 1681, and received another concurrent appointment as "Kyoto Shoshidai" on December 24 of the same year.
