Bakumatsu: Purges, Plots, and a Failing Regime

Episode Narrative

In the year 1858, Japan stood at a crossroads. For centuries, the Tokugawa shogunate had maintained a carefully crafted isolation, a steadfast bulwark against the outside world. But change was on the horizon. The world had become more interwoven, and the once impenetrable walls of Japan were beginning to show cracks. The catalyst for this transformation was the Harris Treaty, signed by Ii Naosuke, the chief advisor, or Tairō, of the Tokugawa regime. This agreement opened Japan to foreign trade, particularly with the United States, which set off a wave of political turbulence.

This decision did not come without cost. The Emperor, considered a divine figure, was not consulted. Many daimyō, the feudal lords who governed the various domains, opposed this sudden shift toward engagement with foreign powers. A deep discontent began to brew among the ruling elite and across the populace. The signing of the treaty acted like a spark in a powder keg, igniting a fervor for reform and a desire to restore imperial authority. Yet, in reaction to this unrest, Ii Naosuke initiated the Ansei Purge from 1858 to 1860. This campaign was brutal and unforgiving, targeting over a hundred officials, scholars, and samurai who championed the cause of imperial restoration. Among those arrested, exiled, or executed were prominent figures from politically significant domains like Mito and Satsuma. It was a decisive moment that revealed the lengths to which the shogunate would go to maintain its waning power.

As discontent simmered, the tension reached a boiling point. On March 24, 1860, Ii Naosuke was assassinated by rōnin, masterless samurai from Mito and Satsuma, at the Sakuradamon Gate in Edo. This shocking event — later known as the Sakuradamon Incident — served as a particularly telling reflection of the declining authority of the shogunate. The assassination was not merely a personal vendetta; it was emblematic of broader struggles between those who wished to uphold the shogunate and those who sought to usher in a new era of imperial power.

In the 1860s, a fervent movement called Sonnō jōi — meaning "Revere the Emperor, Expel the Barbarians" — gained traction. This rallying cry resonated deeply within the hearts of loyalists and progressive rebels alike. The excitement reached fever pitch as domains like Chōshū and Satsuma began openly defying the authority of Edo, launching attacks on foreign ships and legations. Each clash not only represented a confrontation with foreign powers but also a pivotal struggle for Japan’s very identity.

The fervor escalated dramatically in 1863 when the Chōshū domain audaciously bombarded foreign vessels navigating the Shimonoseki Strait. This brazen act of defiance was met with a retaliatory firestorm from Western naval forces — a united front of British, French, Dutch, and American ships unleashed their might upon Chōshū in 1864. The bombardment decimated the domain’s coastal defenses and forced them into a reluctant submission, culminating in the payment of a massive indemnity. For many, this incident was a wake-up call, exposing the grave military weakness of Japan and accentuating the urgent need for modernization.

With the fear of foreign domination looming over them, the urge for reform grew stronger. In 1866, two of the most powerful anti-Tokugawa domains — the Satsuma and Chōshū — formed a strategic alliance. This union represented a significant turning point in the unfolding drama, setting the stage for the eventual overthrow of the shogunate. The Kyoto Imperial Court, under the leadership of Emperor Kōmei and later Emperor Meiji, began to reassert its ritual and political authority, as court nobles and loyalist samurai increasingly questioned the legitimacy of the shogunate.

As the political landscape grew ever more complex, Tokugawa Yoshinobu, the last shogun, attempted a significant maneuver in 1867. He endeavored to restore power to the Emperor in what was termed the “Taisei Hōkan.” Yet, rather than placating the mounting dissatisfaction, this effort was met with outright rejection by those who sought nothing less than the total abolition of the shogunate.

Tensions boiled over into open conflict in 1868, giving rise to the Boshin War. As samurai rallied to either side, battles erupted between the forces loyal to the shogunate and those pressing for the Emperor’s supremacy. The Battle of Toba-Fushimi became the stage upon which the destiny of a nation hung in the balance. The shogunate's defeat in this critical engagement marked the beginning of its end.

By 1868, the Meiji Restoration was formally declared. This proclamation signified not just a change in leadership, but a seismic shift in the very fabric of Japanese governance. With the shogunate crumbling, Japan stood at the dawn of a new era, characterized by the introduction of imperial rule under Emperor Meiji, the new government centered in Tokyo, the transformed city previously known as Edo.

The reforms initiated by the Meiji government were sweeping and systemic. The feudal domains known as han were abolished in 1871, replaced by a series of prefectures. This move directly centralized administrative control and changed the administrative landscape forever. It was also during this period that the Meiji Constitution was promulgated in 1889. This document established a constitutional monarchy with a bicameral legislature, the Imperial Diet. However, in a striking reflection of the old order, real power continued to reside with the Emperor and his inner circle of advisors.

The Meiji government embarked on a deliberate effort to modernize Japan, implementing a new legal code influenced by Western (particularly French and later German) models. The adaptations aimed to translate and fit these concepts into the existing framework of Japanese society, a complex process that began in the 1870s and continued well into the following decade.

Central to this transformation was the establishment of a modern police force and judiciary that replaced the samurai and locally appointed magistrates. The authority of the state expanded, intertwining governance and civil order into a new, centralized structure. Meanwhile, the drive for economic modernization took root in a political environment sowed with urgency. The policy known as “Fukoku Kyōhei,” or “Rich Country, Strong Army,” sought rapid industrialization. It birthed state-owned enterprises that were later privatized, illustrating the government’s shifting relationship with the economy.

Land reforms implemented throughout the 1870s and 1880s transformed the rural landscape. The introduction of private land ownership reshaped agricultural practices and redefined property rights, increasing state revenue significantly. Education reform also became a focal point, with the establishment of a national school system in 1872 aimed at fostering a literate populace, loyal to the nation.

Japan’s foreign policy shifted dramatically from seclusion toward engagement with the global community. Signing treaties with foreign powers allowed Japan to participate in international diplomacy, visible in the production of English-language tourist guidebooks by the 1890s — a compelling sign of the nation stepping onto the world stage.

The military underwent fundamental reforms as well. The creation of a conscript army and navy was modeled after Western practices, with the intent of elevating Japan to the status of a great power. This ambition bore fruit in the Sino-Japanese War of 1894 to 1895, and later in the Russo-Japanese War between 1904 and 1905, where Japan emerged victorious, shocking the world.

The Bakumatsu era, marked by purges, plots, and the eventual disintegration of a millennia-old feudal system, encapsulated not just a shift in power but a profound transformation in the essence of Japanese identity. As Japan rapidly modernized and sought its place among the nations of the world, it was faced with the looming question of its core values. Would the battle against foreign domination lead to a embracing of Western ideals, or would it reinvigorate the intrinsic ties to their own culture and tradition?

As we reflect on this tumultuous chapter, the story of Bakumatsu echoes through time, a reminder of the inevitable cycles of change that forge the path of nations — where the clash of tradition and progress cultivates the spirit of resilience. The dawn of a new era was upon Japan, heralding both an end and a beginning. For centuries to come, the legacy of this conflict would shape the identity and aspirations of a nation.
