西園寺公望
Apart from the Imperial Family, only six Japanese citizens have ever been decorated with the collar in their lifetimes; the last such award was to former Prime Minister Saionji Kinmochi in 1928. Eight others have been posthumously decorated with the collar; the last such award was to former Prime Minister Yasuhiro Nakasone in 2019, as of the end of 2020. Today, only the reigning Emperor holds this dignity as sovereign of the order; however, exceptions are made for foreign heads of state, who can be awarded the collar in friendship.
