When Böckmann came to Japan, he undertook the grandiose project of city planning of Tokyo; it was to set the center of the capital around the area from Tsukiji to Kasumigaseki, and to place buildings, such as a central station, a theater, a venue for exhibitions, government offices, a new palace and a congress hall.
