Tsûsai Sugawara (1894–1981), a popular cultural figure in Japan, started collecting in 1943 and in 1954 established the Tokiwayama Bunko ("library") Foundation, named after and located in the area of Kamakura where he had his private residence. Initially this was opened to the public, but amendments to the Law for the Protection of Cultural Properties have necessitated its closure. Tokiwayama Bunko now exhibits and loans its works at and to other institutions in Japan and overseas, in particular the Kamakura Museum of National Treasures and Tokyo National Museum, as well as making materials available for academic purposes. In recent years there has been a particular emphasis on research and publications relating to Chinese ceramics.[1][2]
