Miyabi
Miyabi (雅) is one of the oldest of the traditional Japanese aesthetic ideals, though perhaps not as prevalent as Iki or Wabi-sabi. In modern Japanese, the word is usually translated as "elegance," "refinement," or "courtliness" and sometimes refers to a "heart-breaker".
The aristocratic ideal of Miyabi demanded the elimination of anything that was absurd or vulgar and the "polishing of manners, diction, and feelings to eliminate all roughness and crudity so as to achieve the highest grace." It expressed that sensitivity to beauty which was the hallmark of the Heian era. Miyabi is often closely connected to the notion of Mono no aware, a bittersweet awareness of the transience of things, and thus it was thought that things in decline showed a great sense of miyabi.
