Modern Buddhist Studies based on the methodology of Indo-European philology has estimated that 'Original Indian Buddhism' is philosophical, rational, reasonable, non-ritualistic and non-magical. This image of Indian Buddhism often deprives a sincere Japanese Buddhist who has been engaged in rites and performing magic of his self-confidence. However, is it really true that there are essential differences between Japanese Buddhism and Indian Buddhism? This question still remains unsettled. This paper attempts to resolve this estrangement established between Japanese and Indian Buddhism by primarily examining some ritual aspects of Indian Buddhism, and moreover proposes clues for reevaluating modern Japanese Buddhism.
