Mitsubishi Ichigokan, Marunouchi's first office building, has been restored as part of an integrated development project with the 34-story Marunouchi Park Building, designated as a special urban renewal district. In addition to restoring materials and details based on preserved materials, the building's seismic-isolated structure restores the original brick masonry and wooden shed structure, which was tested for fire resistance.
