Toshiko (Japanese:智子; 23 September 1740 – 24 December 1813), posthumously honored asEmpress Go-Sakuramachi (後桜町天皇,Go-Sakuramachi-tennō) was the 117thmonarch of Japan, according to the traditionalorder of succession.[1][2] She was named after her fatherEmperor Sakuramachi, with the wordgo (後) before her name translating in this context as "later" or "second one". Her reign during theEdo period spanned the years from 1762 through to herabdication in 1771.[3] The only significant event during her reign was an unsuccessful outside plot that intended to displace theshogunate with restored imperial powers. As of 2026[update], she remains the most recentempress regnant of Japan as the current constitution does not allow women to inherit the throne.[4][5]
Empress Go-Sakuramachi and her brotherEmperor Momozono were the last lineal descendants ofEmperor Nakamikado. Her nephew succeeded her asEmperor Go-Momozono upon her abdication in 1771. Go-Momozono died eight years later after a serious illness with no heir to the throne. A possiblesuccession crisis was averted when Go-Momozono hastily adoptedan 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 thehistory of Japan, Go-Sakuramachi was the last of eight women to take on the role ofempress regnant.
Before Go-Sakuramachi's accession to theChrysanthemum Throne, her personal name (imina) was Toshiko (智子).[6] Toshiko was born into the Imperial family on 23 September 1740 she was the second daughter ofEmperor Sakuramachi, and her mother was Nijō Ieko (二条 舎子).[7] Toshiko had an older sister who died at a young age, and a brother named Toohito who becameEmperor Momozono upon the death of their father in 1747. The empress and her Emperor brother were the last lineal descendants ofEmperor Nakamikado.[8] Toshiko's Imperial family lived with her in thedairi of theKyoto Imperial Palace, her initial pre-accession title wasIsa-no-miya (以茶宮) and laterAke-no-miya (緋宮).
On 15 September 1762 Princess Toshiko acceded to the throne as Empress when her brotherEmperor Momozono abdicated in her favor.[6][9] Momozono's son, Prince Hidehito (later to be known asEmperor Go-Momozono) was only 4 years old at this time. Hidehito's empress aunt was expected to occupy the throne until her nephew would be able to take on the burden of responsibility. While she held the political title ofEmpress, it wasin name only as theshoguns (generalissimos) of theTokugawa family controlled Japan. There was only onemajor incident during Go-Sakuramachi's reign in 1766, which involved unsuccessful plans to displace the shogunate with restored Imperial powers.[10] While the attempt was thwarted, additional challenges to the shōgun's authority would come a decade or so later under the reign ofEmperor Kōkaku. Other events in Go-Sakuramachi's life included the founding of a merchant association handlingKorean ginseng in the Kanda district ofEdo.[11] The year 1770 saw a great comet (Lexell's Comet) with a very long tail light up the night skies throughout the summer and autumn.[12] During the same year two major disasters unfolded which included a typhoon that flattened the newly built Imperial Palace in Kyoto, and the start of a 15 year consecutive drought.[12] Go-Sakuramachi abdicated on 9 January 1771 in favor of her nephewHidehito.[7]
Go-Sakuramachi became aDaijō-tennō (Retired Empress) upon her abdication, but her nephew's reign as Emperor did not last long.Emperor Go-Momozono became deathly ill in 1779, and having no heir to the throne this created a potentialsuccession crisis. Go-Sakuramachi consulted with the senior courtiers and imperial guards, and planned to accept PrinceSadayoshi of Fushimi-no-miya as an adopted son. For one reason or another the choice went instead to Prince Morohito, who was a member of theKanin branch of the Imperial family. Morohito was the sixth son of Prince Kan'in-no-miya Sukehito (閑院宮典仁), and was supported by the Emperor's chief advisor (aka theKampaku). Go-Momozono hastily adopted Prince Morohito, who becameEmperor Kōkaku upon his death on 6 December 1779. After the throne had switched to that branch of the imperial line, Go-Sakuramachi came to be referred to as the Guardian of the Young Lord, referred to the Emperor. The largest event that took place before her death occurred in 1789, when she admonished Kōkaku for his role in a scandal involving his father's honorary title. The former empress Go-Sakuramachi died on 24 December 1813 at the age of 73.[7]
Go-Sakuramachi'skami is enshrined in the Imperial mausoleum (misasagi),Tsuki no wa no misasagi, atSennyū-ji inHigashiyama-ku, Kyoto. Also enshrined in this location are this empress's immediate Imperial predecessors sinceEmperor Go-Mizunoo –Meishō,Go-Kōmyō,Go-Sai,Reigen,Higashiyama,Nakamikado,Sakuramachi andMomozono, along with her four immediate successors –Go-Momozono,Kōkaku,Ninkō, andKōmei.[13]
In thehistory of Japan, Go-Sakuramachi was the last of eight women to take on the role ofempress regnant. She is also credited with creating a book calledMatters of Years in the Imperial Court (禁中年中の事,Kinchū-nenjū no koto), which consists of poems, Imperial letters and Imperial chronicles. Although there were seven other reigning empresses, their successors were most often selected from amongst the males of the paternal Imperial bloodline. For this reason, some scholars have suggested that these reigns were temporary, and argued that the male-only succession tradition must be maintained in the 21st century.[14] The sole exception to this tradition occurred whenEmpress Genmei was followed on the throne by her daughter,Empress Genshō. The other five women to rule as empress with male heirs include:Suiko,Kōgyoku (Saimei),Jitō,Kōken (Shōtoku), andMeishō. After theMeiji Restoration (1868), Japan imported thePrussian model of imperial succession, in which princesses were explicitly excluded from succession. The debate to allow succession laws to be changed allowing for a possible future empress continue to this day, most recently withPrincess Toshi in 2005.
The years of Go-Sakuramachi's reign are more specifically identified by more than oneera name ornengō.[6] WhileKugyō (公卿), is a collective term for the very few most powerful men attached to the court of theEmperor of Japan in pre-Meiji eras. Even during those years in which the court's actual influence outside the palace walls was minimal, the hierarchic organization persisted. In general, this elite group included only three to four men at a time. These were hereditary courtiers whose experience and background would have brought them to the pinnacle of a life's career.
