These two ministries were also called 'Okura-Minbu-sho' by putting together, because leading members from the Kyo down to the Shojo concurrently served as managers of both ministries (for example, Shigenobu OKUMA assumed the post of Taifu of both Okura-sho and Minbu-sho, while Hirobumi ITO assumed the post of Shofu of both Okura-sho and Minbu-sho).
卿以下少丞以上の幹部が両省の役職を兼ねる（例えば、大隈は大蔵兼民部大輔、伊藤は大蔵兼民部少輔に就任する）ことで統一されたため、「大蔵民部省」とも称された。
