Japanese shadows
Tanizaki Jun'ichiro, in his essay In Praise of the Shadow, recounts how in the Japanese domestic organization, and in general in the layout of the interiors, everything was designed to be in semi-darkness. There were numerous screens placed both between the light coming from outside and the domestic environments (large verandas, long and low slopes, not to mention the shōji, the sliding screens that served as external doors and windows), and between the different rooms of stay through, in fact, the fusuma.
