Shibui (渋い) (adjective), shibumi (渋み), or shibusa (渋さ) are Japanese words that refer to a particular aesthetic of simple, subtle, and unobtrusive beauty. Like other Japanese aesthetics terms, such as iki and wabi-sabi, shibui can apply to a wide variety of subjects, not just art or fashion.

In traditional Japanese aesthetics, wabi-sabi (侘び寂び) is a world view centered on the acceptance of transience and imperfection. The aesthetic is sometimes described as one of appreciating beauty that is "imperfect, impermanent, and incomplete" in nature. It is prevalent in many forms of Japanese art.
