Thus, a Temporary Architectural Bureau was formed in the Cabinet in 1886; Inoue assumed the premiership, Michitsune MISHIMA assumed office of the vice-president (concurrently the Tokyo Metropolitan Police commissioner), and Tsumunaga MATSUZAKI, an architect who had returned from Germany, assumed office of the director of construction.
こうして1886年（明治19年）、内閣に臨時建築局を設置し、井上が総裁に、三島通庸が副総裁（警視総監兼務）に、またドイツ帰りの建築家・松崎万長が工事部長に就任した。
