The aim of this article is to present the relation between Christianity and Japanese culture. The problem here is not the concept of Christianity, but the concept of Japanese culture. In the Japanese thought is hard to distinguish between religion and philosophy. Philosophy, religion and culture are synonyms for “philosophy of life”. The original Japanese philosophy is Shinto and received from China Confucianism, and Buddhism. In the case of Christianity we have to consider Catholic Church and Orthodox Church. Special attention we have to pay to the process of inculturation of the Good news in the Japanese soil.
