Yoshimune
The story begins with the death of the seventh Shogun, Tokugawa Ietsugu, a young girl, and the subsequent reign of the eighth Shogun, Yoshimune. She appointed her entourage Kanō Hisamichi as her Osoba Goyō Toritsugi, and carried out various reforms of the shogunate administration. Her decisive reforms also extended to the Ōoku, where three thousand beautiful men were ridiculed as the wasteful spenders of the shogunate. One day, Yoshimune wondered why women had both female and male names. In official documents, all women were listed under male names, and even if they had husbands, they were either not mentioned, or they were purposely listed as wives under female names. She believed that this made it impossible to obtain accurate statistics for the country and harmed the shogunate administration. She met with Murase Masasuke, the head of Yūhitsu, to view the logbooks recording everything in the Ōoku. Masasuke told her that the logbooks were named the Chronicle of the Dying Day by Kasuga, the founder of the Ōoku. Yoshimune asked him what kind of man Kasuga was, but Masasuke revealed that Lady Kasuga was a woman. Yoshimune was surprised and began opening the pages of the logbooks. She thought that reading them would explain why official records used male names even though women were running the country.
Iemitsu
The Chronicle of the Dying Day, as read by Yoshimune, dates back to the rule of the third Shogun, Iemitsu. The redface pox was spreading throughout Japan. Arikoto, a handsome monk of noble birth who had come to Edo Castle from Kyoto, was forcibly returned to secular life along with a boy monk, Gyokuei, under threat from Lady Kasuga, and was admitted to the Ōoku to become Iemitsu's page. However, it was revealed that the original Iemitsu had already died of the redface pox and that Arikoto's entry to the Ōoku was so that Chie, Iemitsu's illegitimate daughter, could give birth to an heir. The truth is that for the sake of the continuation of the Tokugawa clan, the Ōoku had been rewritten by Lady Kasuga to be populated by men.
As Arikoto interacted with Chie, he learned of her difficult upbringing in which she was forced to take the place of the Shogun, and stripped of her life as a woman. Arikoto affirmed Chie's existence as a woman, and Chie also fell in love with him. Filled with affection, Chie began to show her original intelligence and talent for politics.
After the death of Lady Kasuga, Chie announced the death of the original Iemitsu to all the feudal lords in Japan and declared that she would assume the title of Iemitsu herself and rule the country as a female Shogun. The lords, who had been suffering from a decline in the number of male heirs, followed suit, and it became the basic rule that women would inherit the governorship.
Chie, who was unable to have any children with Arikoto, died at the age of 27 after having three children with her concubines, including Gyokuei. Upon Chie's death, Gyokuei was ordained and changed his name to Keishō-in, but Arikoto was not ordained and remained in the Ōoku as the Toshiyori (Ōoku) under Chie's last will.
Ietsuna
Chie's eldest daughter, Chiyo, became the fourth Shogun, Ietsuna, at the age of 11. She was nicknamed "Lady Do So" because of her lack of interest in politics and her "You may do so" attitude toward the advice of shogunate officials. However, with the help of Arikoto and other outstanding vassals from her mother's time, her shogunate maintained stability.
On the night of the Great fire of Meireki in Edo, Ietsuna is alone with Arikoto while evacuating the castle, and suddenly confesses her love for him. After Arikoto helped to restore the Ōoku from the fire, he was ordained, changing his name to Eikō-in and left the Ōoku. Ietsuna died without an heir, and the fifth Shogun was Tsunayoshi, the daughter of Chie and Keishō-in.
Tsunayoshi
Tsunayoshi became the fifth Shogun, and together with her Sobayōnin, Yanagisawa Yoshiyasu, she demonstrated political skills that were a complete change from those of her predecessor, while at the same time using her lovely and bewitching appearance to lead a wild sex life. Tsunayoshi fell in love with Lady Emonnosuke, a candidate for a Concubine brought from Kyoto by her Official Husband, Takatsukasa Nobuko, but Emonnosuke declined the position due to his age, and instead accepted the position of the General Director of the Ōoku.
Just then, Tsunayoshi was forced to have another child due to the sudden death of Matsu (Tokugawa clan), the only heir she had already had. This led to an intensified power struggle for Tsunayoshi's favor between her father Keishō-in, Emonnosuke, and the Concubines who represented each of them. Tsunayoshi could not ignore her father's affection for her, continued to have sexual intercourse with young men even after she reached menopause, and her reputation declined in Edo, aided by the Akō Incident and the Edicts on Compassion for Living Things. Tsunayoshi, who was unable to rule well and produce an heir, wondered why she was still alive, but Emonnosuke told her that the relationship between a woman and a man was not limited to procreation. Tsunayoshi, who was united with Emonnosuke, broke the curse of her father and nominated Ienobu, the daughter of Tsunashige, whom her father disliked, as the next Shogun, but Emonnosuke died suddenly soon after.
Later, her father, Keishō-in, died, and Tsunayoshi contracted measles and became critically ill. Her Chief Retainer, Yoshiyasu, visited Tsunayoshi on her sickbed and suffocated her to death while confessing her secret feelings for Tsunayoshi. Her death was officially ruled as death by measles, and Yoshiyasu left Edo Castle as Ienobu assumed the shogunate.
Ienobu
The story takes place a little further back in time, during the rule of Tsunayoshi. Katsuta Sakyō, who was living a life of idleness in Edo, was picked up after being injured in a betting dispute by Manabe Akifusa, Ienobu's Chief Retainer. Sakyō eventually fell in love with Akifusa, but she intended to make him Ienobu's Concubine. Sakyō met Ienobu and was impressed by her personality, and they had a child together, Chiyo, who would later become her successor.
Ienobu, who became the sixth Shogun, struggled to correct Tsunayoshi's maladministration and was expected by the common people to be a stateswoman, but due to frailty, she died three years after assuming the shogunate. At this time, Sakyō had a half-hearted one-night stand with Akifusa, who was disturbed by her proprietress's death, which became the prelude to the Ejima-Ikushima affair.
Ietsugu
Upon Ienobu's death, Ienobu's Official Husband, Kunihiro, changed his name to Konoe Hiroko and Sakyō changed his name to Gekkō-in, and both became ordained. Ienobu and Gekkō-in's daughter, Chiyo, became the seventh Shogun, Ietsugu. Ietsugu, only four years old, was so sickly that she was in danger of failing to reach adulthood, and there was a conflict in the Ōoku between Ten'ei-in of Yoshimune in the Kishū Domain faction and Akifusa and Gekkō-in of Tsugutomo in the Owari Domain faction over who should be the next Shogun. At that time, Ejima, the General Director of the Ōoku, who was on Gekkō-in's side, was captured as a result of the Ejima-Ikushima affair. It was a plot by Yoshimune's faction to force him to testify against Gekkō-in and Akifusa for their infidelity, but Ejima denied everything and was sentenced to death. Gekkō-in asked Ten'ei-in to spare Ejima's life and maintain the treatment of Akifusa after the change of Shogun in exchange for Yoshimune's nomination as the next Shogun, which Ten'ei-in accepted.
As a result, Yoshimune was chosen as the eighth Shogun. Ietsugu then died of illness at the age of seven.
Ieshige
Yoshimune, who had learned about the history of the Ōoku and Japan up to this point from reading the unofficial record, the Chronicle of the Dying Day, feared that she would be invaded by foreign nations with few men in Japan, and began efforts to eradicate the redface pox. At the same time, Yoshimune also made groundbreaking political reforms and was soon blessed with three daughters, and her rule seemed secure. However, Ieshige, the eldest daughter, had language disorder, while Munetake, the second daughter, was good-looking and intelligent, so much so that people suggested that Ieshige be disinherited and Munetake become the heir. Yoshimune, who knew that Ieshige's intelligence was normal and that she suffered from physical disabilities, declared that Ieshige would be the next Shogun, but Ieshige's character was distorted by the prejudice and ridicule she was subjected to, and she spent her days indulging in drinking and lust. The negative legacy of Yoshimune's rule, natural disasters, and the fact that Yoshimune was still alive and well as the Ōgosho (Edo period), led Ieshige's rule to be regarded as incompetent as a Shogun. On the other hand, Ieshige's Chief Retainer, Tanuma Okitsugu, was recognized by Yoshimune for her insightful talents and began to play an active role on the political stage.
After Yoshimune's death, Okitsugu followed Yoshimune's wishes and embarked on measures to combat the redface pox. She invited Aonuma, a mixed blood who had studied Dutch medicine in Japan in Nagasaki, to give lectures on Dutch studies to the men in the Ōoku, and gathered information from Hiraga Gennai, who traveled around the country. In the process, Aonuma concluded that preventive measures, rather than curative measures, should be taken against the redface pox.
Ieharu
Ieshige handed over her shogunship to her eldest daughter, Ieharu, and retired to the Nishinomaru Palace in Edo Castle. Ieharu appointed Okitsugu as an Elder and entrusted her with the overall management of the shogunate and the redface pox. Okitsugu's skills earned her great support from the Ōoku and the shogunate officials, but her promotion of Dutch studies and mercantilism led some of her subjects and the common people of Edo to become displeased with her. In addition, behind the scenes, Yoshimune's granddaughter and the head of the Hitotsubashi Tokugawa family, Tokugawa Harunari, began to play a dark role.
Meanwhile, Aonuma and Kuroki, who had learned Dutch studies from Aonuma, searched for a method of preventing the redface pox and arrived at the variolation method based on information obtained from Western books. Gennai found a patient with attenuated pox, and the method was successful, but among those inoculated, Matsudaira Sadanobu's nephew died from the side effect. In addition, Okitsugu lost her power due to a series of natural disasters, including the Tenmei eruption and the Great Tenmei famine, the death of Ieharu's successor Tokugawa Iemoto, and the assassination of Okitsugu's daughter, Tanuma Okitomo, which led to her downfall at the same time as Ieharu's death. Aonuma was condemned to death, and Kuroki, who had studied Dutch studies, and others were banished from the Ōoku. Gennai contracted syphilis as a result of Harunari's plot and died, and Kuroki, who was left behind, expressed his anger at the unreasonableness of the situation.
Harunari was expected to become the 11th Shogun, but she announced that her son Ienari would become Shogun. Harunari persuaded the shogunate officials that Ienari had been vaccinated by Aonuma and others, and that there was no need to worry about the possibility of redface pox. This resulted in the birth of Ienari, the first male Shogun since Iemitsu.
Ienari
Although Ienari was inaugurated as a male Shogun, he was not allowed to meddle in politics, and the real power was in the hands of his mother, Harunari. She forced Ienari to have children, while she assassinated them out of boredom. Ienari contacted Kuroki behind Harunari's back and had them resume their research on redface pox in secret. Eventually, Kuroki and his team arrived at a vaccination using attenuated redface pox bear as the seed and succeeded in preventing the plague without any side effects. However, the fame of the vaccine reached Edo Castle, and it was revealed to Harunari that Ienari had been secretly helping his research on the redface pox.
Harunari tries to poison Ienari, but at that moment, it is Harunari who falls ill from the poison. Ienari's Official Wife Kōdai-in (Shige) and his Concubine Keimei-in realized that it was Ienari who had poisoned their children, and over the years they had been planning to assassinate Harunari while deceiving even their husband Ienari. Shiga, who had herself been poisoning Harunari for many years, died on the spot, and Harunari, although she survived, was unable to speak or move.
Ienari then exercised his true power as the Shogun and half-assedly promoted the spread of vaccination against the redface pox. As a result, the male population recovered rapidly and the Kasei culture reached its zenith. Ienari handed over his shogunship to his son Ieyoshi but continued to hold political power as the Shogun Emeritus, and a few years later, Ienari reconciled with Shige, with whom he had been estranged since the attempted poisoning of Harunari, and died.
Ieyoshi
While the restoration of the male population has led to a resurgence of inheritance by male samurai, the Abe family, which has served the Tokugawa family for many years, had a female head of the family, Abe Masahiro. Masahiro, who had achieved much success as a Magistrate of the Temples and Shrines, was promoted by a shogunate official to the position of Elder at a young age, although the number of women in the shogunate was declining. Masahiro took in Takiyama (Elder in Ōoku), a male prostitute from a samurai background, whom she had known well, and invited him to work with her for Japan and the Shogun.
In 1853, the year of the Perry Expedition, the 13th Shogun was inaugurated by Iesada, daughter of Ieyoshi.
Iesada
Iesada had been sexually abused by her father, Ieyoshi, since she was a child. Masahiro, who came to Edo Castle as an Elder, sensed this and, with the help of Kōdai-in (formerly Shige), succeeded in enclosing Iesada in the inner part of Nishinomaru to protect her from Ieyoshi. Takiyama was appointed as the General Director in charge of the inner part of Nishinomaru. On the other hand, Ieyoshi's obsession with Iesada remained unabated, and two of Iesada's Official Husbands were assassinated in succession.
The situation in Japan was changing, and the Jōiron was on the rise; when Matthew C. Perry arrived in Japan in 1853, there was uproar in Edo, Ieyoshi panicked and died suddenly, and Iesada was appointed Shogun. Masahiro solicited the opinions of samurai, townspeople, and farmers alike, and the establishment of the Nagasaki Naval Training Center and the conclusion of the Convention of Kanagawa marked the end of the isolationist regime that had existed for 200 years.
Then, Iesada married Shimazu Taneatsu again. Iesada found out that Taneatsu was on a mission to install Yoshinobu of the Hitotsubashi family as the next Shogun by a trick of the Satsuma Domain. However, Iesada's personality touched Taneatsu, and he devoted himself to Iesada wholeheartedly, and Iesada also opened her heart to Taneatsu. Iesada eventually became pregnant with Taneatsu's child but died before the last month of pregnancy. In accordance with Iesada's will, Taneatsu changed his name to Tenshō-in without being ordained and adopted Tomiko from the Kishū Tokugawa family to become the next Shogun.
Iemochi
Soon after Tomiko changed her name to Iemochi and became Shogun, the Ansei Purge occurred. As part of the Union of the Imperial Court and the Shogunate, a wedding was to take place between Emperor Kōmei's brother, Prince Kazu and Iemochi, but when he arrived, he was a woman dressed as a man. She revealed that she was Chikako, the sister of the real Prince Kazu, and that she had taken the place of her brother who did not want to go to the wedding. This was an act of her desire to win the affection of her mother, Hashimoto Tsuneko, who was always fond of her brother, but Iemochi stood by her, and Chikako opened her heart to Iemochi.
Meanwhile, in the political world, friction between exclusionists and Kaikoku had begun to surface, and the Satsuma Domain was asked to reform the shogunate administration, which led to the appointment of Yoshinobu as the Shogun's Apotropos. However, despite his intelligence, Yoshinobu failed to win the support of all parties because of his arrogant attitude, and the Council of Advisors, which was established to discuss future politics, was dissolved after only two months. Various interests, including those of Satsuma Domain, Chōshū Domain, and the Imperial court, became entangled, and the survival of the Tokugawa shogunate was in jeopardy.
Then, Iemochi fell ill with thiamine deficiency. Concerned about the future of her country, the Tokugawa shogunate, and Chikako, Iemochi, despite her illness, went to Kyoto to see Emperor Kōmei, but she died in the capital. Iemochi's will that her adopted son Kamenosuke should be the next Shogun was crushed, and Yoshinobu became the last Shogun of the shogunate.
The end of the Ōoku
Although the war between the shogunate and the Chōshū Domain was averted on the pretext of Iemochi's death, the end of the shogunate government was no longer inevitable with the return of power to the Imperial court. Fearing that he would be slandered as a dynastic enemy by the new government forces that had taken the name of the Imperial army, Yoshinobu retreated from the front lines. Katsu Kaishū, who had been given full authority over the shogunate forces by Yoshinobu, went to talk with Saigō Takamori, the commander of the new government forces, to prevent a general attack on Edo. Takamori pressed Kaishū to hand over Yoshinobu or fight back in Edo. Takamori argued that Yoshinobu's death was necessary to bring to naught the shameful history of the Tokugawa, who had ruled the country by women. Hearing this, Chikako was furious and intervened, revealing that she was a woman, and demanded that the general attack be called off, citing the case of Prince Kazu's substitution and the involvement of Iwakura Tomomi on the side of the new government in the poisoning of Emperor Kōmei. As a result, Takamori agreed to state that all Shoguns of the Tokugawa family for generations were men, and the bloodless fall of Edo Castle was accomplished. Instead of the entire history of the Tokugawa women being buried in darkness, the city of Edo and its people, whom they had protected and loved, were preserved.
In 1871. Tenshō-in, a Satsuma man on a Western voyage as Shimazu Taneatsu, told a little girl, Tsuda Umeko, who is going to study on the same ship: "Even a woman can become a person to run a country. This country was once ruled by women for generations."
