Although under the Fujiwara clan the regent came to be thought of as a bureaucratic post to be held concurrently by a minister, which was an official post, in 986 at the time of FUJIWARA no Kaneie, he quit his position as Udaijin (Minister of the Right), which was an official post (Shokujikan), to become only a regent with an official rank but no post (Sankan).
藤原氏のもとで摂政は職事官である大臣に付随して兼務する官職と考えられてきたが、寛和2年（986年）藤原兼家の時に職事官である右大臣を辞任して摂政のみを占める散官になった。
