The main buildings of the palace grounds, including the main palace, home of the liaison conference of the Imperial General Headquarters, were severely damaged by the fire of May 1945. Today's palace consists of multiple modern structures that are interconnected. The palace complex was finished in 1968 and was constructed of steel-framed reinforced concrete structures produced domestically, with two stories above ground and one story below. The buildings of the Imperial Palace were constructed by the Takenaka Corporation in a modernist style with clear Japanese architectural references such as the large, gabled hipped roof, columns and beams.
