Empress Go-Sakuramachi

Empress Go-Sakuramachi was born Princess Toshiko to Emperor Sakuramachi and Nijō Ieko [ja] in 1740.^[1] She was the middle of three children, Princess Noriko, older, who died age 10 and Prince Toohito, younger, later Emperor Momozono.^[4][5] Her father died when she was young, and so the Tokugawa shogunate granted her mother some land, and gave the princess herself 300 koku of land as there was no intention for her to enter a nunnery.^[6]

Her brother was sickly and had only one child, a young boy.^[7] It was unusual for the emperor to come to the throne without the backing of a Daijō Tennō, the retired emperor, and so Momozono named his sister as his heir in his will.^[7] The emperor's death was hidden for a day and due to the urgency of the situation, since she was the last lineal descendent of Emperor Nakamikado, the court did not alert the shōgunate in Edo beforehand about their decision.^[7]

The top clans in the country secretly met with each other to confirm their support for Toshiko as Momozono's successor.^[8] In 1762 Go-Sakuramachi came to the throne.^[9]

Her reign was contested by some nobles, including commander Nomiya Sadaharu who argued that it was unusual to enthrone a female emperor in modern times, and that Go-Sakuramachi's female predecessor, Empress Meishō, could not count as precedence for a modern female emperor since she was an "example from a strange and degenerate age".^[10] He lamented "Alas, this is a time when the royal way has declined and fallen into decay in the latter days", further saying "It has never been heard of that a younger brother should cede the imperial throne to his elder sister or brother".^[10] He finally wrote of his anger that it was "as if his mind and spirit were torn asunder".^[10] Her enthronement crown caused the enthronement to be postponed, as the crown of the previous female emperor, Meishō, had been lost.^[11] It was suggested the crown of Empress Shōtoku be used, but regent Konoe Uchisaki rejected this, and so a crown based on one worn on a statue of Tokugawa Masako was made instead.^[11]

The Seishi Gusho [ja], which spans over 500 years of imperial history notes that her enthronement ceremony and the following rituals such as the Daijosai were mostly the same as male emperors and she even wore robes with dragons on them to her Daijōsai. However, aside from new years ceremonies she rarely attended court rituals. Aside from this, the only really significant thing in her reign was an unsuccessful plot to overthrow the shōgun, and while not directly linked or involved, she may have shared some of the pro imperial/nationalist sentiments.^[7]

In 1771, she abdicated in favour of her nephew, Emperor Go-Momozono.^[9] She taught and looked after him, telling him after the birth of his daughter (which led to much worry over if he'd have a son) "You're still young, so I'm sure you'll be blessed with a prince in due course", but he died at age 22, leaving behind his new born daughter.^[7][12] Thus, the Emperor's death was kept a secret, as Go-Sakuramachi adopted Prince Morohito, making him heir. He was of the Kan'in-no-miya branch of the imperial family and would become Emperor Kōkaku.^[7]

In order to ensure the connection and unity of the two branches, she married Kōkaku to her grandniece, and only child of her nephew, Princess Yoshiko.^[13]

She worried over the new emperor greatly, who was nine years old, and wrote to the former regent of Japan that she still relied on him and needed his help.^[7] She also wrote to the new emperor: "May the winds of this land, beloved by the people, blow gently in this first spring of your reign".^[7]

While she moved to the Sentō Imperial Palace in Kyoto, she was known to often visit the new emperor.^[12]

The new emperor, now in his 20s, wanted to elevate the status of his father.^[12] This caused outrage with the court nobles, and the former empress advised: "Rather than seeking higher titles or status, ensuring that your reign lasts for a long time is the greatest act of filial piety you can show your father", to which the emperor took her advice.^[12]

During the Great Tenmei famine, thousands flocked to the imperial palace, offering prayers and money hoping for good fortune.^[14] While it started small, it grew into tens of thousands of people per day, and people began throwing coins at the palace gate, praying, and holding festivities.^[14] This became known as Gosho Sendo Mairi [ja], and the former empress began handing out apples to pilgrims, ordering that rice and water be brought out to them as well which increased her popularity.^[12][14][15]

This, along with her teachings to Emperor Kōkaku in which she taught him compassion and benevolence to the people, earned her the nickname "Mother of Japan".^[12]

Empress Go-Sakuramachi died on 24 December 1813, aged 73, 11 months after the death of her adopted son's biological mother, Ōe Iwashiro.^[16][17]

As of 2026, she remains Japan's last female emperor, though there is an ongoing debate to allow Emperor Naruhito's only child, Aiko, Princess Toshi, to become Japan's ninth empress regnant.^[18]

Aside from this, today she is remembered as "Mother of the Nation" or "National Mother".^[12][19]

The years of Go-Sakuramachi's reign are more specifically identified by more than one era name or nengō.^[20] While Kugyō (公卿), is a collective term for the very few most powerful men attached to the court of the Emperor 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.

• Hōreki (1751–1764)
