Kane-bugyō

Kane-bugyō were financial officials of the Tokugawa shogunate and of a number of daimyō domains in early modern Japan. They were responsible for the custody, accounting and disbursement of cash stored in official treasuries, and formed part of the broader fiscal administration overseen by the kanjō-bugyō.
In the shogunate, the Kane-bugyō were classified as hatamoto officials under the jurisdiction of the kanjō-bugyō. Standard reference works describe the office as having four regular posts with stipends of around 200 koku, and note that similar positions existed in many domains, where they supervised domain treasuries and cash flows.

Historical development

The functions associated with the Kane-bugyō grew out of the development of separate cash treasuries within the Tokugawa fiscal system. The shogunate established okane-gura at Edo, Osaka, Nijō, Sunpu and Kōfu to hold gold and silver reserves. Edo’s treasuries, in particular, were divided between an inner treasury within the main bailey and the Hasuike treasury inside the Terasawa Gate.
Initially these treasuries functioned mainly as emergency reserves to be used in war, major fires in Edo, or large-scale famines. Over time, however, they evolved into general-purpose treasuries handling the routine intake and outlay of shogun revenues in cash. The kane-bugyō in Edo and Osaka were responsible for all accounts associated with such receipts of cash. These were compiled and then subsequently audited by the katte-kata. The entire operation was closely scrutinized by a member of the rōjū or the wakadoshiyori.
By the eighteenth century, the Edo treasuries had become important repositories of the shogunate’s cash savings. Standard Japanese entries describe the Kane-bugyō as officials in both the shogunate and in various domains, responsible for the management and cash in-and-out of the treasury, explicitly stating that, in the shogunate, they were subordinate to the kanjō-bugyō.

List of ''Kane-bugyō''

Because Kane-bugyō were mid-level officials, their names are usually preserved only in specialist prosopographical works, genealogies of hatamoto families, or local histories. A number of identifiable office-holders, however, appear in well-known historical episodes or have been documented by local governments.
Ōtaka Gengo – A retainer of the Akō domain better known as one of the “Forty-Seven Rōnin”, Ōtaka is described in Akō local-history materials and genealogical notes as having served in several posts including kitchen service and arms supervision, and as a Kane-bugyō before the fall of the domain.
Maehara Isuke – Another Akō retainer, Isuke appears in Akō city tourism and heritage materials as a close page and Kane-bugyō of the domain. The city’s description of his former residence notes that he combined his role as a close attendant of the lord with responsibilities for the domain treasury.
