Tokugawa Ienobu
The Honchō Gunki Kō ("Thoughts on Japanese Military Equipment"), a military manual written in 1709 by Arai Hakuseki (1657–1725), lays out standard measurements for jinmaku. Arai, an advisor to the "shōgun" Tokugawa Ienobu, recorded that a jinmaku should be tall and wide. The number of , or poles for hanging the jinmaku, was set at 10 for a "taisho" officer and 8 for other soldiers, tethers only in white, black, or blue, and "mon" clan emblems placed in between three, five, or seven places. In the Edo period military science became popular among samurai and gave religious meaning to jinmaku as a sacred item.
