[10] In much the same sense as the British Crown, the Chrysanthemum Throne is an abstract metonymic concept that represents the monarch and the legal authority for the existence of the government.

[12] In the 1920s, then-Crown Prince Hirohito served as regent during several years of his father's reign, when Emperor Taishō was physically unable to fulfill his duties.

[14] The metonymic meanings of "Chrysanthemum Throne" encompass the modern monarchy and the chronological list of legendary and historical monarchs of Japan.

For the Enthronement of Emperors Akihito and Naruhito, both the Takamikura and Michodai thrones were taken apart, refurbished and reassembled at the Seiden State Hall of the Imperial Palace in Tokyo where the ceremonies are now held.

[15][16][17] The throne features real gold with details such as the 16 petal chrysanthemum seal, two lion heads, two phoenixes and the sun disc.

"[18] e.g., During the 2007 state visit by the Emperor and Empress of Japan to the United Kingdom, the Times reported that "last night’s dinner was as informal as it could get when the House of Windsor entertains the Chrysanthemum Throne.
