Ōsei Fukko no Daigōrei (Imperial Restoration Proclamation)

The Ōsei Fukko no Daigōrei — the Imperial Restoration Proclamation — was one of the most sweeping political declarations in Japanese history. Issued on the ninth day of the twelfth month of Keiō 3 (January 3, 1868), it abolished the offices of regent and shogun, which had defined Japanese governance for a thousand years, and proclaimed the establishment of a new government headed by three newly created posts: the Sōsai (President), Gijō (Deliberators), and Sanyo (Junior Councilors).

The Political Vacuum After the Return of Power

The return of political power on the fourteenth day of the tenth month of Keiō 3 had removed Tokugawa Yoshinobu from the shogunate, but left the concrete organization and policy of the new government undefined. The Satsuma-Chōshū alliance and radical court nobles led by Iwakura Tomomi moved swiftly to fill this vacuum and seize the initiative before Yoshinobu could establish himself as a dominant figure in any new deliberative council of domain lords.

In the predawn hours of the ninth day of the twelfth month, Iwakura Tomomi, Saigō Takamori, and Ōkubo Toshimichi organized the occupation of the nine gates of the imperial palace by Satsuma troops, blocking pro-shogunate court nobles from entering and convening a court council on their own terms. It was effectively a coup within a coup — but executed in the name of the emperor.

Content of the Proclamation

The proclamation declared: the abolition of the regent's office (sesshō and kampaku), ending more than a millennium of regency politics; the abolition of the shogunate, bringing the 265-year Edo order to a definitive end; the creation of the Three Posts of the new government; and a declaration of return to direct imperial rule, invoking the founding of the realm by Emperor Jinmu.

The Kogo-sho Conference

That same night, the first council of the new government convened in the Kogo-sho (Small Hall) of the Kyoto Imperial Palace, attended by representatives of Satsuma, Tosa, Aki (Hiroshima), Echizen (Fukui), and Owari. The central question was the treatment of Yoshinobu: should he be required to resign his office as Inner Minister (Naidaijin) and return his domains? Tosa's Yamauchi Yōdō argued forcefully that the Tokugawa should be allowed to participate in the new council rather than be stripped of status. Iwakura countered that Yoshinobu's sincerity was being tested, and the Satsuma-Chōshū hard line prevailed. Yoshinobu's resignation and the return of his domains were decided — a fatal blow to his remaining influence, and the effective end of the Edo shogunate.

Swords and the Restoration

The twelfth month of Keiō 3 was the final act of the bakumatsu. The Satsuma troops who surrounded the imperial palace held the gates with sword and musket — the armed reality behind a political proclamation. For the court nobles of the radical faction, the blades of the Satsuma soldiers were the indispensable guarantee that their political will would be realized.

Among the warriors who shaped these events, Matsudaira Katamori of Aizu had upheld loyalty to the shogunate throughout the turmoil. The fate of Aizu, designated an "enemy of the court" by the Restoration, and the swords that embodied the domain's martial spirit, represent the tragic dimension of bakumatsu sword culture. The blades carried by Satsuma loyalists, tempered in the tradition of the Jigen-ryū school's explosive cutting technique, stood in counterpoint to the refined collections of the shogunal house.

Historical Significance

The Imperial Restoration Proclamation proclaimed the ideal of direct imperial rule while its actual character was a coup by the Satsuma-Chōshū alliance — a duality that would be inscribed into the structure of Meiji state power. The pattern of placing the emperor at the symbolic center while Satsuma-Chōshū politicians exercised real authority became the foundational arrangement of the Meiji government. Within a month, the Battle of Toba-Fushimi ignited the Boshin War. The Restoration was not a peaceful transition but the prologue to conflict — yet in the arc leading to the bloodless surrender of Edo Castle, the Imperial Restoration Proclamation stands as the irreplaceable founding document of modern Japan.
