“Shōgun of the Thirteen Days”

“Shōgun of the Thirteen Days” is a mocking epithet for Akechi Jinsai that compresses his brief rebellion into a memorable measure of its duration. The name is recalled in conversation alongside the alternative “Ju-san Kubo,” linking the label to both the Taikō’s contempt and the rebellion’s abrupt end.

The Name and Its Referent

The speaker explains that the Taikō sneeringly dubbed Akechi Jinsai “Ju-san Kubo, Shōgun of the Thirteen Days.” The expression does not establish that Jinsai formally held the office of shōgun; in this account, it is the Taikō’s derisive designation for him. Its force comes from the contrast between the grandeur of the title and the brevity of the revolt it names.

The Thirteen-Day Rebellion

The stated span runs from Jinsai mustering his men to the rebellion’s conclusion in his seppuku. The epithet thus turns a sequence of political and military action into a compact chronology: the rebellion began with the assembling of forces and ended in ritual death only thirteen days later. The recollection calls Jinsai a fine man, while also emphasizing that his hatred of the foreigners arose from their foreignness, not from their Christianity.

The Recollection’s Political Context

The account adds a personal charge to the nickname’s history. Jinsai often accused the speaker of poisoning Goroda against him, an allegation the speaker denies. The same exchange raises, without resolving, whether Mariko became Christian in order to learn the foreigners’ ways and destroy them. These remarks situate the epithet within a recollection shaped by suspicion between Jinsai and the foreigners, rather than presenting it as a neutral historical title.
