Nanga (南画 "Southern painting"?), also known as Bunjinga (文人画 "literati painting"?), was a school of Japanese painting which flourished in the late Edo period among artists who considered themselves literati, or intellectuals. While each of these artists was, almost by definition, unique and independent, they all shared an admiration for traditional Chinese culture. Their paintings, usually in monochrome black ink, sometimes with light color, and nearly always depicting Chinese landscapes or similar subjects, were patterned after Chinese literati painting, called wenrenhua (文人画) in Chinese.
The name nanga is an abbreviation of nanshūga, referring to the Chinese Southern School of painting (nanzhonghua in Chinese).
Chinese literati painting focused on expressing the rhythm of nature, rather than the technical realistic depiction of it. At the same time, however, the artist was encouraged to display a cold lack of affection for the painting, as if he, as an intellectual, was above caring deeply about his work. Ultimately, this style of painting was an outgrowth of the idea of the intellectual, or literati, as a master of all the core traditional arts – painting, calligraphy, and poetry.
Due to the Edo period policy of sakoku, Japan was cut off from the outside world almost completely; its contact with China persisted, but was greatly limited. What little did make its way into Japan was either imported through Nagasaki, or produced by Chinese living there. As a result, the bunjin (literati) artists who aspired to the ideals and lifestyles of the Chinese literati were left with a rather incomplete view of Chinese literati ideas and art. Bunjinga grew, therefore, out of what did come to Japan from China, including Chinese woodblock-printed painting manuals and an assortment of paintings widely ranging in quality.
