Throughout the creative career of Koda Rohan，The Billows Dashing to the Skies and Fate are two important turning points in his creative journey. Taking these two works as milestones，Rohan completed the identity transformation from a writer to a scholar，and then to a scholar-writer. His research activities were not due to his distaste for creation，but an active exploration to break through the bottleneck of creation. It is worth noting that after experiencing the failure of writing novels，Rohan was no longer satisfied with just trying within the framework of novels，and historical biographies also became one of his exploration directions. The publication of Yoritomo is another transformation of his creative style，and it is also something that cannot be ignored when examining his later creations. This research takes the establishment of the awareness of the theme of “god worship” in Rohan’s creation process as the starting point，and by comparing the different manifestations of the theme of god worship in his genre creation，studies and analyzes Rohan’s Yoritomo and the works of the same period such as The Billows Dashing to the Skies，conduct a comprehensive and detailed examination of the development of genre consciousness in Yoritomo.
