The purpose of this paper is to outline historical unfolding procedure and its nature, and review reformism and reality recognition of the Buddhism world in the early 20th century by connecting them to the age of colony. In addition, its another purpose is to research the enlightened civilization of Buddhism and its effort to search for religious way out. Although Buddhism had almost no equity of tradition when it was compared to main order represented by Confucianism, on the contrary, it could search for Apologeticus-type change in the age of the enlightened civilization by escaping from tradition. However, the subjective search for the enlightened civilization collided with the wall of reality, colonialism, so the reformism and reform movement did not significantly escape from the autonomy and improvement of reformism within the system. The only way to complete the journey of enlightened civilization was the independence as a modern religion. However, the original restriction of colonialism prevented Buddhism from growing as a modern religion as well as an ethnic religion. It means that the superficial change or imitation without the accumulation of internal reflection and modernism was not sufficient to achieve subjective and religious modernism.
