A blank, unpainted space. It is considered one of the identifying characteristics of both Chinese and Japanese painting. Blank space is not simply unpainted areas; it is important to the composition of a painting and carries the same "weight" as the painted areas, often serving to set off or balance the painted motifs.
As early as the 10th century in China, ink landscape painters attempted to capture the spirit of the scenery around them; in their paintings, blank space functioned as "spirit" ki 気. During the Northern Song dynasty, literati artists accompanied their paintings with lyrical poems brushed onto the blank space of a painting. Later in the Southern Song dynasty, artists like Ma Yuan (Jp: Ba En 馬遠, act. late 12th-early 13th century) and Xia Gui (Jp: Ka kei 夏珪, act. 1194-1224) balanced their one-corner compositions with copious amounts of blank space. The Zhe school Seppa 浙派 of the Ming dynasty and their artistic heirs in Japan, the Kano school *Kano-ha 狩野派, adapted blank space to large painting surfaces. The followers of Chan Buddhism in China, Zen 禅 in Japan, used ink soaringly along with blank space in their paintings to represent the symbolic "nothingness" or mu 無 inherent in their ideology. In screen paintings and handscrolls from the Heian to the Kamakura periods, blank space was used to represent pictorial depth and movement through time. In large-scale paintings from the late Muromachi period through the Edo period, backgrounds of gold-leaf were substituted for blank space, but functioned in generally the same way. Later on in the Edo period, even artists like Maruyama Ōkyo 円山応挙 (1733-95) and his followers *Maruyama Shijō-ha 円山四条派 who were interested in depicting images close to actual scenes, continued to employ blank space in traditional ways.
