A public facility jointly operated by Japan Post Co. Ltd. and the University Museum, the University of Tokyo (UMUT) has opened within the JP Tower in the Marunouchi district. In the former Tokyo Central Post Office, a five-storied historical building representative of Showa modernism architecture, the second and third floors were renovated as a museum space to give birth to the Intermediatheque (IMT). As indicated by its name, this is a facility dedicated to interdisciplinary experimentation venturing into cultural creation of a new kind based on the fusion of every means of expression. The platform of such an activity is the permanent exhibition of the scientific and cultural heritage accumulated by the University of Tokyo since its foundation in 1877. The design policy conducting the revival of this historical heritage within the contemporary urban cityscape is one of the highlights of the exhibition. Special exhibitions and events will also present the fruits of contemporary scientific research and artistic expression in harmony with the permanent exhibition. The Intermediatheque’s unique activities also include an original comprehensive education program, as well as a boutique presenting original goods emanating from the museum’s activities.
