Dominant Religions in China and Japan: Folk/Confucian/Buddhist vs. Shinto/Buddhist

China: No single "world religion" dominates numerically. The prevailing framework is Chinese folk religion—a syncretic blend of ancestor veneration, Confucian ethics, Taoist ritual, and Buddhist practice. Formal adherence: ~20% Buddhist, ~5% Christian, ~2% Muslim; but most participate in folk customs.

Japan: Shinto (indigenous kami worship) and Buddhism coexist; most Japanese practice both (Shinto for life events, Buddhism for funerals). Surveys show ~70% Shinto, ~67% Buddhist (overlap). Christianity ~1%.

Neither fits a "single dominant world religion" model; both are pluralistic, syncretic systems.
