The University of Tokyo is composed of three campuses: Hongo, Komaba and Kashiwa. In addition, some University of Tokyo facilities are situated in other parts of both Tokyo and the country. The main campus of the university is located in Hongo Bunkyo-ku, Tokyo and occupies about 56 hectares of the former Kaga Yashiki, the Tokyo estate of a major feudal lord. Parts of the seventeenth century landscaping of the original estate have been preserved to provide greenery and open space. The campus is graced by the Kaga Estate's celebrated Akamon, or Red Gate, which dates from 1827 and has been designated as an 'Important Cultural Property' by the Japanese Government. Most of the faculties, graduate schools, and research institutes of the university are located on the Hongo Campus.
