The original TWCU campus in Iogi-mura, Toyotama-gun, to which the university moved in 1924, was built in the 1920s and is very significant architecturally. It was designed by Antonin Raymond who came to Tokyo with Frank Lloyd Wright to build the famous Imperial Hotel. The university includes seven registered tangible cultural properties, including the main building. In addition to TWCU’s beautiful garden, the campus includes open spaces and a small forest behind the main building. In the forest, there are various plants such as plum trees, cherry trees, dogwood trees
