Following Kazuo Osumi’s method of linking historical figures with the method of “like”, a database of historical figures is created using the classical texts of Japan and China owned by Kodansha Gakujutsu Bunko (Academic Library,Kodansha Ltd.).It elucidates the self-perception of Japanese Japan as a miniature of the Han Empire through the cases of Emperor Temmu, Kiyomori Taira, and Emperor Godaigo who identified themselves as Liu Bang,Wang Mang, and Liu Shu.In addition to this,my paper pointed out the existence of ‘like’due to the birth of the causal concept of retribution.This was a global transgender ‘like’that transcended national and gender boundaries.The Japanese medievalists lived in such a world.
