This paper examines the content of the Japanese Samurai spirit, which is comparable to the Korean Seonbi spirit, focusing on its relationship with Confucian thought. Specifically, the paper discusses the distinctive nature of Nitobe Inazo's ‘Bushido’, which spoke of Samurai morality based on universal Confucianism, Tsuda Sokichi's Bushido theory which totally rejected the influence of such Confucianism, and the spread of Confucianism which began in earnest with the end of warfare in the Edo period through Nakae Tojyu and Yamaga Soko. (...) First, I argue that Nitobe's Bushido developed Bushido based on Confucianism, which refers to universal morality, but that it also encompassed values specific to Japan due to the historical circumstances of the Sino-Japanese and Russo-Japanese wars. Next, I pointed out that Tsuda's Bushido theory, which he criticized, was an argument based on historical grounds that put the actual lives of warriors in the foreground, but was limited in that it unilaterally emphasized only the historical particularities of Japan and downplayed the role of Confucianism as a universal ideology. Next, the creation of a new Samurai spirit through Confucianism in the Edo period, or the content of the Confucian Shido theory, through Tojyu's viewpoint of Bunbu Ittoku and Soko's emphasis on external dignity, revealed that although the Sonbi spirit and the Samurai spirit are based on the same Confucianism, the two are as dissimilar as the conflicting images represented by Bun and Bu.
