The Kansei era’s kibyōshi is often called the Reform period’s kibyōshi （“Kaikaku no kibyōshi”）, which the critical artistic method for this genre was emphasized in the previous research of the same topic. In such famous kibyōshi as Bunbu Nidō Mangoku Dōshi or Ōmugaeshi Bunbu no Futamichi were, Matsudaira Sadanobu and his reform policies which were the main aim of kibyōshi’s sarcasm. However, by analyzing comprehensively this era’s kibyōshi dealing with politics, it is revealed that there were less critical or even positive evaluations of Sadanobu. For instance, Taihei Gongen Chinza no Hajimari, a kibyōshi from Kansei 1（1789）, that wasn’t widely noticed thus far, uses Aoto Fujitsuna’s portrayal, who was a historical hero in the Taiheiki, as an allude for Matsudaira Sadanobu. In this type of kibyōshi, using Fujitsuna as an image for Sadanobu, we are not able to recognize criticism against the young rōju, rather we take notice of some expectations regarding the new politics. The kibyōshi published one year later, from Kansei 2（1790）, Sadanobu’s positive evaluation has vanished. Still, this literary process can be explained with the rotation of the kibyōshi writer’s social status while the bushi authors were replaced with chōnin authors.In this research, a new approach of the valuation of kibyōshi published between Tenmei 8（1788） and Kansei 3（1791）will be presented regarding text alteration, the politically critical side of Reform period’s kibyōshi, detailed political information, and shift in the author’s social status, while arguing the genres expressive style pointing out that, in front of the common accepted theory, kibyōshi wasn’t the genre that fostered only critics against politics, however, in a certain period, it also made an affirmative political evaluation. In addition, exploration from the perspective of the author’s intention: why was Aoto Fujitsuna used as the metaphor of Matsudaira Sadanobu in the kibyōshi? Through analyzing literary genres and other historical sources, a brief examination of Aoto Fujitsuna’s character’s alteration from the latter part of the Middle Ages to the Edo period and point out that Fujitsuna’s image became a very stable ideal for the common people by the Kansei era, therefore Fujitsuna depicted in literary genres was able to spread a positive evaluation through the kibyōshi even though the genre used a critical expressive style.
