The uniqueness of the Japanese sense of beauty --- shadowsJunichiro Tanizaki (2011) said that "beauty does not exist in the object but in the ripples and the brightness of shadows created by objects” in his work “In Praise of Shadows” to express his opinion on the Japanese sense of the beauty of shadows (p. 35). In aesthetic dictionaries, shadow is vividly described as "the light and shadow cast by numerous branches of foliage on the ground." The ancient Japanese discovered and appreciated the beauty of shadows, which made shadow aesthetics a unique Japanese aesthetic tradition. On the other hand, Europeans developed a totally different aesthetic tradition which advocated light and the sun. This report will first compare the different aesthetic traditions. The roof is huge and heavy despite the temples, palaces and farms in Japan. The interior space is full of shadows under the tall roofs, and people can't even distinguish the walls and pillars. Japanese people like to see the golden sun outside when staying in areas inaccessible to light. They appreciate this kind of beauty and the beauty of the Japanese house totally depends on the degree of shade (Junichiro Tanizaki, 2011). The Japanese are also accustomed to building corridors around the house and installing paper doors to weaken the sunlight, hoping to use large roofs. By using these ways, they can create a shadow environment in their home. In terms of tokonoma, shadow beauty is also applied. Tokonoma is a recessed space integrated into the Japanese house, so the inserted light will be dimmed, which creates a sense of mystery. Many hanging scrolls are not famous or perfect themselves, but they become classic once hung in the tokonoma because the blurred image is more suitable for the Japanese sense of beauty, they think the vague ancient poetry and painting are more picturesque. European homes, however, are strongly influenced by light. The ideal European home is a clean, bright place where the windows should be polished so that the sun can fully penetrate. The living room fireplace is not only used for heating in winter but also for lighting during a long night. The park, generally Western diamond culture, is more rational and focuses on its formation mechanism and the beauty of the structure, with more logical thinking but less imaginary thinking, more scientific exploration but less humanistic precipitation. Westerners pay more attention to its crystal structure, internal structure and material composition. They try to study diamonds from a natural and scientific point of view in order to understand nature and explore scientific knowledge which is a purely logical and knowledge seeking culture. In fact, they have no stone culture, but only stone science, geology and mineral science. However, people try to give meanings to jades and appreciate these meanings in oriental. Easterners focus more on the character of jades, for example, people appreciate the shadows and faint light emitted by jades because they think it is a kind of implicit and restrictive character that fits their aesthetic.
