Oku (奥) is a spatial theory or concept that pertains to the idea of "inwardness". It is unique to Japan and is an integral part of the urban space formation in the country. The term entails several abstract connotations such as profundity and can be used to describe not only physical but also psychological depth.
Fumihiko Maki proposed his theory of oku in his work, Japanese City Spaces and the Concept of Oku.
Oku is demonstrated in the architecture of the Shimane Museum of Ancient Izumo. It features a steel wall that runs along the approach to the museum while the landscaping that dominates the scene does not establish a focus.
Fumihiko Maki is a Japanese architect. In 1993, he received the Pritzker Prize for his work, which often explores pioneering uses of new materials and fuses the cultures of east and west.
