Takamikura, a formal imperial chamber used at the enthronement ceremony in which an Emperor seats himself to symbolically represent his Imperial Throne, is located in Shishinden in Kyoto Gosho, and thus, at the time of the Ceremony of Enthronement "Seiden no Gi" for the current Emperor (corresponding to "Shishinden no Gi") the Takamikura was temporarily relocated to the Imperial Palace in Tokyo.
即位の際に天皇が着座し、その即位が象徴的に示される天皇の正式な御座所である高御座は京都御所の紫宸殿にあるため、今上天皇の即位の礼「正殿の儀」（「紫宸殿の儀」に相当）に際しては皇居宮殿に一時移設された。
