In this paper, I focused on the motifs of “Raizin” and “Isozeseri” about the creative story of Iiku’s work Gokan “KanenochuruHoridasibugen” and “SichihukunokamiKuzukago”. The story about having a sister as a wife and the good deeds of the previous life had become the main source of the creative story with focusing on the motifs of “Raizin” in “Horidasi”. In particular, the first volume incorporating motifs of “Raizin” was a complete creative story with unrelated to the previous work “Tonbogaeri” and the illustrations. Meanwhile, 4 pages of the latter part in “Sichihuku” mainly formed collecting the Gokan“habit of Isozeseri”, forming a creative story by adding a story of having a son-in-law. Specifically, the back story of the case developed in “Iso” is told by the words of mistress of a brothel in “Sichihuku”, and the ending part of both works coincides with the words, and although the person's name is changed, it was completely match. In this way, the overall motif of the Gokan “Iso” that develops over 30 pages is used by abstract and extracted form in order to develop over 4 pages in Gokan “Sichihuku” which is assembly of various motifs. Also, there was a preceding Kotkeibon “YononakaHinpukuron”, the motif that the concubine brought in by the requested other’s money eventually becomes his concubine has been succeed in Ikku’s work. As mentioned above, “Raizin”, wife and the previous life were taken up about the creation story of “Horidasi”. The story and illustration of “Iso” were taken up about the creation story of “Sichifuku”. As a result, it showed the charts of the outline and composition so that we can understand the mutual influence relationship and creation story of the three works “Tonbogaeri”, “Horidasi” and “Sichifuku”.
