I was careful analysis of how to represent “Chusingura” world about the text ToriiKiyomitsu work Kurohon “ChusinKananoKakizome” the (1765 annual publication). As a result, it is not only borrowed the person’s name that previous research has pointed out, creative methods characteristic of only the Kurohon and pointed out the pioneering device ahead of the subsequent genre, presenting the authority that is different from the previous research could be. Of its creation method, in the case that follows the name of the original, it is considered to be divided into a case of making a new name. It can be said that if one person is responsible for the role of two or more persons in the original, it’s renaming, but this is the characteristics of the Kurohon not much use Kusazosi later. As authority of the Kurohon, in addition to the person’s name IwanagaZaemon of “DannouraKabutoGunki” and NinomiyaHangan of “HaruHukamiIrohasoga” were pointed out in the prior literature, in relation “secret letter which are given in the back”by the episode that was common, it was found that the as authority “GobanTaiheiki” and “ChusinKoganenoTanzaku”. Still, I discussed the possibility that from the side to be used is device of “Yoritomo”, falconry, and “Koiso”, aware of the world of general “Soga group”.
