Abstract: Yin and Yang culture in China and Japan has the shared origin and exerts significant impact on the two countries, which has farreaching influence on philosophy, literature, religion, art and folk custom of the two countries. But so far only a few studies have been done on the comparison in China. With the origin of Yin and Yang culture between China and Japan as the starting point, this paper compares the essential characteristics of them, such as the original and exotic, gradual and abrupt, speculative and specific, and also compares their extension characteristics, such as the development history, spread way, application scope, then explores the differences and similarities of Yin and Yang culture between China and Japan by using the method of combining the horizontal and vertical, comparison diachronic and synchronic. It aims at providing a theoretical reference and effective example to study the outside influence of Chinese culture and the successful mode of Chinese traditional cultures “going out”.

Key words: Yin and Yang culture in China and Japan, origin, essential characteristics, extension characteristics, different branches of the same source

摘要： 中日阴阳文化同源异流，各有千秋，对两国的哲学、文学、宗教、艺术、民俗等产生了广泛而深远的影响，但目前国内有关中日阴阳文化的比较研究并不多见。通过横向和纵向相结合、历时与共时相比较，以中日阴阳文化起源渊源为基点，从中日阴阳文化的内发性和外促性、渐进性和突变性、思辨性和具象性等本质内涵，以及发展历程、流播途径、应用范围等外延视角来综合研究两者的异同，为正确理解中日阴阳观念，为中国传统文化域外影响研究和中国文化 “走出去”研究提供理论参考与有效范例。
