In principle, if an official obtained the third rank, i.e., status of high court noble, he was permitted to enter the Imperial Palace; however, a noble of the fourth or fifth rank, or even a chamberlain of the sixth rank were permitted to enter the Imperial Palace ('Tenjobito') if they were given imperial sanction.
原則として三位の位階を得れば（公卿身分の獲得）昇殿が許され、四位・五位の貴族や六位でも蔵人の地位にあるものは勅許があれば昇殿が許されていた（殿上人）。
