In this study, I compared Syomono with Rendaku which was shown at christian material Nippozisyo(1603-1604). Also, I examined the degree of differences between confucianism world and the general world and whether there was any confusion between them. As a result, firstly, the phenomenon of Lendaku at Syomono did not occur at Nippozisyo(1603-1604). Secondly, at Nippozisyo, both endaku were registered. From this, I could see that there was a difference at both materials. in the Muromachi era. Rendaku phenomenon that was Kasataha followed nasal sound lines led to Rendaku was confirmed at the Chinese chareacters Syomono. the result of the comparison of synonyms of amnesty suggests that there was a considerable difference of Rendaku between the general world and the world of Confucianism in the Muromachi era.
