Tokyo International Forum recalling the history of the site and surrounding area

The site on which the Tokyo International Forum (TIF) was built is the intersection of the Daimyokouji, which housed rows of city residences (kamiyashiki) of Japanese feudal lords (daimyo) in the Edo period, and the current Babasaki-dori where city residences (kamiyashiki) of the Tosa and Awa feudal domains were located.
Since the development of the surrounding area, dubbed the London Block of Marunouchi (Marunouchi Itcho London)for its red-brick European style buildings, and the shift of the Tokyo Government Office Buildings to this area in the same period of 1894 and up to the relocation of these Buildings to Shinjuku in 1991, it has functioned as the modern and present-day center of Tokyo’s administration for approximately one century.
At the same time, one could say that this location has consistently served to lead the economy and culture of Japan, including the surrounding areas of Otemachi, Marunouchi, and Yurakucho, down to the present day.
The Tokyo International Forum opened in this area in January 1997 as a center for promoting and communicating comprehensive culture and information. It serves as a base for carrying out a wide range of cultural activities, a place for creating and exchanging various information, and a hub for international exchanges.
