When Emperor Showa passed away in 1989, the national ceremony called Taiso no Rei (the Rites of an Imperial Funeral) was held separately from the Imperial Family's ceremonies called Sojoden no Gi and Renso no Gi in order to comply with the principle of the separation of politics and religion according to the Constitution of Japan.
1989年の昭和天皇の場合には、日本国憲法の政教分離原則に反しない形で国家儀式の大喪の礼と皇室儀式の葬場殿の儀・斂葬の儀が分離された。
