The modern study of Japanese aesthetics only started a little over two hundred years ago in the West. The Japanese aesthetic is a set of ancient ideals that include wabi (transient and stark beauty), sabi (the beauty of natural patina and aging), and yugen (profound grace and subtlety). These ideals, and others, underpin much of Japanese cultural and aesthetic norms on what is considered tasteful or beautiful. Thus, while seen as a philosophy in Western societies, the concept of aesthetics in Japan is seen as an integral part of daily life. Japanese aesthetics now encompass a variety of ideals; some of these are traditional while others are modern and sometimes influenced by other cultures.
