The Chrysanthemum Throne (皇位 kōi , lit. "Imperial position/rank") is the English term used to identify the throne of the Emperor of Japan. The term also can refer to very specific seating, such as the takamikura (高御座) throne in the Shishin-den at Kyoto Imperial Palace.
Various other thrones or seats that are used by the emperor in an official function, such as in Tokyo Imperial Palace or the throne used by the Emperor in the Diet of Japan during ceremonies associated with the delivery of his Speech from the Throne, are however not known as "Chrysanthemum Throne".
Japan is the oldest continuing hereditary monarchy in the world. 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. Unlike its British counterpart, the concepts of Japanese monarchy evolved differently before 1947 when there was, for example, no perceived separation of the property of the nation-state from the person and personal holdings of the emperor.
According to legend, the Japanese monarchy is said to have been founded in 660 BC by Emperor Jimmu and the current Emperor is the 125th monarch to occupy the Chrysanthemum Throne. The extant historical records only reach back to Emperor Ōjin, who is considered to have reigned into the early 4th century.
In the 1920s, Hirohito served as Regent during several years of his father's reign, when Emperor Taishō was physically unable to fulfill his Imperial duties. However, the Prince Regent lacked the symbolic powers of the throne which he could only attain after his father's death.
The current Constitution of Japan considers the Emperor a "symbol of the state and the unity of its people." The modern emperor is a constitutional monarch. The metonymic meanings of "Chrysanthemum Throne" encompass the modern monarchy and the chronological list of legendary and historical monarchs of Japan. It is a term with fungible uses.
The throne Takamikura (高御座) is located in the Kyoto Imperial Palace and is the oldest surviving throne used by the monarchy. It sits on an octagonal dais, five meters above the floor, and could be separated from the rest of the room by a curtain. The sliding door that hid the Emperor from view is called the kenjō no shōji (賢聖障子), and had an image of 32 Chinese saints painted upon it, which became one of the primary models for all of Heian period painting. The throne is used mainly for the enthronement ceremony, along with a twin throne for the empress-consort.
Rhetorical usage 
This flexible English term is also a rhetorical trope. Depending on context, the Chrysanthemum Throne can be construed as a metonymy, which is a rhetorical device for an allusion relying on proximity or correspondence, as for example referring to actions of the Emperor or as "actions of the Chrysanthemum Throne." The Chrysanthemum throne is also understood as a synecdoche, which is related to metonymy and metaphor in suggesting a play on words by identifying a closely related conceptualization, e.g.,
- referring to a part with the name of the whole, such as "Chrysanthemum Throne" for the mystic process of transferring Imperial authority—as in:
- December 18, 876 (Jōgan 18, on the 29th day of the 11th month): In the 18th year of Emperor Seiwa's reign (清和天皇18年), he ceded the Chrysanthemum Throne to his son, which meant that the young child received the succession (‘‘senso’’). Shortly thereafter, Emperor Yōzei is said to have formally acceded to the throne (‘‘sokui’’).
- referring to the whole with the name of a part, such as "Chrysanthemum Throne" for the serial symbols and ceremonies of enthronement—as in:
- January 20, 877 (Gangyō 1, on the 3rd day of the 1st month) Yōzei was formally installed on the Chrysanthemum Throne; and the beginning of a new nengō was proclaimed.
- referring to the general with the specific, such as "Chrysanthemum Throne" for Emperorship or senso—as in:
- Before Emperor Yōzei ascended to the Chrysanthemum Throne, his personal name (his imina) was Sadakira Shinnō (貞明親王).
- referring to the specific with the general, such as "Chrysanthemum Throne" for the short reign of Emperor Yōzei or equally as well for the ambit of the Imperial system.
During the State Visit in 2007 of 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."
