Meiji Restoration - Decline of the Shogunate and Anti‑Tokugawa Alliances

The Decline of the Tokugawa Shogunate Introduction During the 1850s and 1860s, Japan experienced a dramatic political transformation that ended over 250 years of Tokugawa rule. This decline wasn't simply a military defeat—it resulted from a complex interaction between foreign pressure, internal political divisions, and the rise of a new movement among samurai and domains who sought to restore imperial authority. Understanding this period requires tracing how foreign treaties created domestic opposition, how ambitious samurai organized resistance, and how two major domains united to fundamentally reshape Japanese politics. The Treaty Crisis and Anti-Foreign Sentiment The opening of Japan to foreign trade in the 1850s created an immediate and intense backlash among the Japanese political elite. When the Tokugawa shogunate signed the unequal treaties—particularly the Convention of Kanagawa—opponents were horrified. These treaties granted Western powers extraterritoriality (immunity from Japanese law), low tariffs, and most-favored-nation status, meaning Japan could not control its own trade or legal system. The opposition crystallized around a powerful slogan: sonnō jōi, meaning "revere the Emperor, expel the barbarians." This movement reflected a genuine belief that the Emperor held a sacred, supreme authority that the shogunate had overstepped by signing away Japanese sovereignty to foreigners. The slogan itself reveals an important political shift: critics used imperial authority as a weapon against the bakufu (the shogunate's military government). The Ii Naosuke Crisis In 1858, Ii Naosuke became tairō, or chief minister—the highest position in the bakufu below the shogun. Despite fierce opposition from the Imperial Court and anti-treaty factions, Ii ratified the Harris Treaty with the United States. This was a consequential act of political courage or arrogance (depending on perspective): Ii acted in the shogunate's traditional interest, but in direct defiance of the Emperor's wishes. This defiance was intolerable to anti-Tokugawa forces. In 1860, discontented samurai assassinated Ii Naosuke. His death served as a turning point: it showed that the traditional bakufu authority could be challenged through violence, and it energized the anti-shogunate movement. The Rise of the Shishi The assassination of Ii Naosuke emboldened a new political force: the shishi, or "men of spirit." These were lower- and middle-ranking samurai—not the daimyō (domain lords) themselves, but ambitious warriors who served them. The shishi were driven by two beliefs: genuine reverence for the Emperor as Japan's supreme authority, and conviction that direct action, including violence, was necessary to restore imperial rule. One notable early shishi was Yoshida Shōin, an intellectual and activist who plotted the assassination of a senior official in 1859. He was executed for his conspiracy, but his fate did not discourage others—it inspired them. The shishi represented a dangerous wildcard in Japanese politics: they were willing to assassinate prominent officials and could not be easily controlled by the daimyō who nominally employed them. Foreign Military Humiliation and the Shifting Alliance Between 1863 and 1864, two military incidents demonstrated the weakness of the bakufu and accelerated the collapse of the shogunate's authority. First, the Imperial Court issued an order to expel all foreigners—a direct command that reflected the power of the sonnō jōi movement at court. Chōshū Domain, responding to this imperial command, fired on foreign ships in the Shimonoseki Strait in 1863. This action provoked a sharp international response: Britain, France, the Netherlands, and the United States coordinated the Shimonoseki campaign against Chōshū. The domain was forced to open its ports to foreign trade. Second, in August 1864, British warships bombarded the city of Kagoshima, capital of Satsuma Domain, after Satsuma failed to compensate a British merchant. This bombardment was shocking: it struck at one of Japan's most powerful domains, demonstrating that no Japanese domain could resist foreign military force. These incidents had a subtle but crucial effect: they discredited the "expel the barbarians" ideology. It became clear that Japan could not resist the Western powers militarily. The focus shifted instead to "enrich the country, strengthen the military"—a more pragmatic approach that emphasized importing Western weapons and military technology rather than imagining Japan could eliminate foreign presence. The First Chōshū Expedition and Satsuma's Unexpected Turn In autumn 1864, the bakufu declared Chōshū in rebellion and launched the First Chōshū Expedition. Crucially, Satsuma Domain, one of Japan's most powerful territories, cooperated with the bakufu—Satsuma forces under Saigō Takamori participated in the expedition against Chōshū. This cooperation, however, proved temporary. By 1865, Chōshū's leadership—including Takasugi Shinsaku, Itō Hirobumi, Inoue Kaoru, Kido Takayoshi, and military innovator Ōmura Masujirō—adopted the new strategy of strengthening their domain militarily. They imported British weapons and began modernizing their forces. Saigō Takamori, the Satsuma commander, began to shift his views. He came to believe that Tokugawa authority itself was the problem, not regional rebels like Chōshū. The Formation of the Satsuma-Chōshū Alliance The turning point came in early 1866. A crucial mediator emerged: Sakamoto Ryōma, a former samurai from Tosa Domain who became one of the most important political figures of this era. Sakamoto had a unique skill: he could connect Japanese domains with British merchants in Nagasaki who illegally supplied weapons, bypassing the bakufu's prohibition on domain weapons trade. On March 7, 1866, Sakamoto successfully brought together Kido Takayoshi (representing Chōshū) and Saigō Takamori (representing Satsuma) to formalize an alliance against the Tokugawa shogunate. Why was this alliance so consequential? Historian W.G. Beasley identified three major political issues that needed resolution for any anti-Tokugawa coalition to form: Foreign policy: The alliance reduced the focus on "expel the barbarians," replacing it with military modernization. This solved the foreign-policy disagreement. Feudal discipline: By incorporating ambitious shishi loyalists into domain government positions, both Satsuma and Chōshū addressed the problem of uncontrollable samurai violence while channeling their energy toward anti-bakufu goals. Bakufu power: The remaining question was whether to actually overthrow Tokugawa authority—and the alliance committed both domains to answering "yes." The bakufu, meanwhile, was preparing the Second Chōshū Expedition to crush domain resistance to Tokugawa authority. By summer 1866, however, the situation had reversed dramatically: Chōshū rapidly mobilized to repel any bakufu operations, and when the bakufu requested military assistance from neighboring domains, most either refused or gave noncommittal responses. The bakufu's authority was collapsing. The Imperial Transition and Final Crisis (1867) The death of Shogun Tokugawa Iemochi during the Second Chōshū Expedition forced the bakufu to seek a truce with the Imperial Court. This breathing space didn't save the shogunate—it merely delayed the inevitable. In February 1867, Emperor Kōmei died unexpectedly. He was succeeded by his young son, Mutsuhito, who became Emperor Meiji. This transition was significant: the teenage emperor would become the symbol of Japan's new order. Shogun Tokugawa Yoshinobu, the last Tokugawa to hold power, attempted to negotiate a settlement. He offered mediated proposals to the anti-Tokugawa alliance, but they ignored his overtures. Instead, the bakufu announced military, administrative, and financial reforms designed to strengthen Tokugawa authority. Four powerful daimyō—Date Munenari, Matsudaira Yoshinaga, Yamauchi, and Shimazu Hisamitsu—responded by negotiating directly with the shogun. Rather than accepting the bakufu's compromises, they demanded fundamental changes: opening the port of Kōbe and reconsidering policy toward Chōshū. Their opposition signaled that even traditional bakufu allies were now aligned against Tokugawa power. The Final Proposal: Sakamoto's Eight-Point Plan As the crisis deepened, Sakamoto Ryōma drafted an Eight-Point Plan that became the blueprint for ending Tokugawa rule. The plan called for: Expanding and modernizing the military Reforming the legal system Establishing a bicameral legislature Returning political power to the Imperial Court The Tosa Domain submitted this plan as a proposal to the shogun, designed to persuade him to resign his powers voluntarily. This peaceful transfer of authority—though not actually accepted by the bakufu—represented the intellectual foundation for the Meiji Restoration. Rather than simply overthrowing the shogunate through civil war, reformers imagined a transformation where the shogun would voluntarily return power to the Emperor, who would then rule with a modern political system. The bakufu's rejection of this proposal meant that the transfer of power would come through conflict rather than negotiation. Within months, military forces aligned with the anti-Tokugawa alliance would march on the capital, ending the shogunate definitively.
