Order of the Chrysanthemum
Certain eminent prime ministers have been awarded the Order of the Chrysanthemum, typically in the degree of Grand Cordon. The highest honour in the Japanese honours system, the Collar of the Order of the Chrysanthemum, has only been conferred upon select prime ministers and eminent statesmen; the last such award to a living prime minister was to Saionji Kinmochi in 1928. More often, the Order of the Chrysanthemum has been a posthumous distinction; the Collar of the order was last awarded posthumously to former prime minister Yasuhiro Nakasone in November 2019. The Grand Cordon has typically been posthumously awarded; the most recent such award was to Ryutaro Hashimoto in July 2006.
