Shogunate in the context of "Heian period"

The emperor of Japan is the hereditary monarch and head of state of Japan. The emperor is defined by the Constitution of Japan as the symbol of the Japanese state and the unity of the Japanese people, his position deriving from "the will of the people with whom resides sovereign power". The Imperial Household Law governs the line of imperial succession. Pursuant to his constitutional role as a national symbol, and in accordance with rulings by the Supreme Court of Japan, the emperor is personally immune from prosecution. By virtue of his position as the head of the Imperial House, the emperor is also recognized as the head of the Shinto religion, which holds him to be the direct descendant of the sun goddess Amaterasu. According to tradition, the office of emperor was created in the 7th century BC, but the first historically verifiable emperors appear around the 5th or 6th centuries AD.

The role of the emperor of Japan has historically alternated between a largely ceremonial symbolic role and that of an actual imperial ruler. Since the establishment of the first shogunate in 1192, the emperors of Japan have rarely taken on a role as supreme battlefield commander, unlike many Western monarchs. Japanese emperors have nearly always been controlled by external political forces, to varying degrees. Between 1192 and 1867, the shōguns, or their shikken regents in Kamakura (1203–1333), were the de facto rulers of Japan, although they were nominally appointed by the emperor. After the Meiji Restoration in 1868, the emperor was the embodiment of all sovereign power in the realm, as enshrined in the Meiji Constitution of 1889. Since the enactment of the 1947 constitution, the role of emperor has been relegated to that of a ceremonial head of state without even nominal political powers. The emperor is the head of the Japanese honors system, conferring orders, decorations, medals, and awards in the name of the state and on behalf of its people in accordance with the advice of the Cabinet.

Bakumatsu (幕末; Japanese pronunciation: [ba.kɯ.ma.tsɯ], 'end of the bakufu') were the final years of the Edo period when the Tokugawa shogunate ended. Between 1853 and 1867, under foreign diplomatic and military pressure, Japan ended its isolationist foreign policy known as sakoku and changed from a feudal Tokugawa shogunate to the modern empire of the Meiji government. The major ideological-political divide during this period was between the pro-imperial nationalists called ishin shishi and the shogunate forces, which included the elite shinsengumi swordsmen.

Although these two groups were the most visible powers, many other factions attempted to use the chaos of bakumatsu to seize personal power. Furthermore, there were two other main driving forces for dissent: first, growing resentment on the part of the tozama daimyō (or outside lords), and second, growing anti-Western sentiment following the arrival of Matthew C. Perry. The first related to those lords whose predecessors had fought against Tokugawa forces at the Battle of Sekigahara in 1600, after which they had been permanently excluded from all powerful positions within the shogunate. The second was to be expressed in the phrase sonnō jōi, or "revere the Emperor, expel the barbarians". The turning point of the Bakumatsu was during the Boshin War and the Battle of Toba–Fushimi when pro-shogunate forces were defeated.

Shishi (志士), sometimes known as Ishin Shishi (維新志士), were a group of Japanese political activists of the late Edo period. While it is usually applied to the anti-shogunate, pro-sonnō jōi (尊皇攘夷; lit. 'Revere the Emperor, Expel the Barbarian[s]') samurai primarily from the southwestern clans of Satsuma, Chōshū, and Tosa, the term shishi is also used by some with reference to supporters of the shogunate, such as the Shinsengumi.

There were many different varieties of shishi. Some, such as the assassins Kawakami Gensai, Nakamura Hanjirō, Okada Izō, and Tanaka Shinbei, opted for a more violent approach in asserting their views. Kawakami Gensai, in particular, is recalled as the assassin of Sakuma Shōzan, a renowned pro-Western thinker of the time. Several assaults on westerners in Japan have been attributed to the shishi and associated rōnin warriors. In a 2013 article, these assassins have been called "early terrorists" (German: frühe Terroristen) since they opted to spread terror among the foreigners. Other more radical shishi, such as Miyabe Teizō, plotted large-scale attacks with little regard for public safety. Miyabe himself was one of the ringleaders of the plot, foiled by the Shinsengumi at the Ikedaya Incident, to burn Kyoto at the height of the Gion Festival.

Since the enactment of the 1947 constitution, the emperor has been relegated to an entirely ceremonial and representative role, without even nominal political powers. The emperor is the head of the Japanese honors system, conferring orders, decorations, medals, and awards in the name of the state and on behalf of its people in accordance with the advice of the Cabinet.

Toshiko (Japanese: 智子; 23 September 1740 – 24 December 1813), posthumously honored as Empress Go-Sakuramachi (後桜町天皇, Go-Sakuramachi-tennō) was the 117th monarch of Japan, according to the traditional order of succession. She was named after her father Emperor Sakuramachi, with the word go (後) before her name translating in this context as "later" or "second one". Her reign during the Edo period spanned the years from 1762 through to her abdication in 1771. The only significant event during her reign was an unsuccessful outside plot that intended to displace the shogunate with restored imperial powers. As of 2025, she remains the most recent empress regnant of Japan as the current constitution does not allow women to inherit the throne.

Empress Go-Sakuramachi and her brother Emperor Momozono were the last lineal descendants of Emperor Nakamikado. Her nephew succeeded her as Emperor Go-Momozono upon her abdication in 1771. Go-Momozono died eight years later after a serious illness with no heir to the throne. A possible succession crisis was averted when Go-Momozono hastily adopted an heir on his deathbed upon the insistence of his aunt. In her later years, Go-Sakuramachi became a "guardian" to the adopted heir, Emperor Kōkaku, until her death in 1813. In the history of Japan, Go-Sakuramachi was the last of eight women to take on the role of empress regnant.
