Chinese characters of Kanji were oriented to the beauty of symmetry in up-and-down and right-and-left from the era of their composition so that the symmetrical formation of Yin-Yang-He-Yi was already accepted in that era. On the other hand it is identified that one lexicon as well as one symbol of each Japanese character of Kanji were used into two kinds, for instance a phonogram and logogram and also a Chinese-derived reading and Japanese-derived reading. Thus there is an attribute of merging two things into one such as harmonisation of one Yin and one Yang into one word formation in Japanese. In short, Chinese is a cubic unification representing antonym having opposite elements into one symmetrical formation “2→1” while Japanese is linear unification “1+1→1”. Therefore, this paper concludes that these different unifications made essence of traditional culture in both countries.
