In June 1866, Japan and several Western treaty powers signed a tariff convention that standardized most import and export duties at a low 5% ad valorem (value-based) rate. This limited Japan’s ability to protect new industries with higher tariffs and reduced government revenue from trade. The agreement became an important driver of later Meiji efforts to recover tariff-setting authority as part of treaty revision.
The Meiji Restoration created a new national government that prioritized “unequal treaty” revision as a central foreign-policy objective. The earlier treaties restricted sovereignty in multiple ways, including foreign control over tariffs and extraterritorial legal privileges for foreigners in Japan. Recovering control over trade policy became tied to broader legal and institutional modernization.
From 1871 to 1873, the Iwakura Mission traveled to the United States and Europe to study Western institutions and to explore revising the unequal treaties. The delegation found that major powers expected Japan to modernize its legal system before they would accept ending extraterritoriality or loosening tariff constraints. The mission’s limited diplomatic progress reinforced the idea that domestic reforms were a prerequisite for regaining economic sovereignty.
In 1876, Japan concluded a treaty with Korea that opened ports and granted Japanese subjects extraterritorial privileges. Scholars often discuss this as Japan adopting elements of the same treaty-port and legal framework that Western powers had imposed on Japan earlier. The episode reflected Japan’s growing regional power even while it still lacked full tariff autonomy at home.
In the late 1880s, Japanese leaders pursued draft agreements that would end extraterritoriality but also included compromises on tariff control and legal jurisdiction. Public criticism grew when proposals appeared to preserve foreign privileges or delay Japan’s full authority over trade policy. The backlash showed that tariff autonomy had become a highly visible symbol of sovereignty, not just a technical customs issue.
On July 16, 1894, Japan and the United Kingdom signed a new Treaty of Commerce and Navigation. It was a major breakthrough because Britain’s agreement encouraged other powers to negotiate revised treaties as well. The treaty set the stage for ending extraterritoriality and reshaping the legal and economic rules of Japan’s foreign trade.
In November 1894, the United States and Japan concluded a new treaty of commerce and navigation, replacing the earlier 1858 framework. This aligned the U.S. relationship with Japan’s broader treaty-revision push and anticipated the wider shift away from the treaty-port legal order. The change mattered because tariff policy and legal jurisdiction were negotiated across multiple partner countries, not through a single agreement.
In April 1895, Japan and Qing China signed the Treaty of Shimonoseki ending the First Sino-Japanese War. The outcome increased Japan’s international standing and bargaining power in diplomacy. This stronger position supported Japan’s longer campaign to be treated as an equal state, including in negotiations over trade rules and tariff authority.
On July 17, 1899, the Anglo-Japanese treaty entered into force, and Britain’s extraterritorial courts in Japan ceased for new cases. Similar revised treaties with other powers also took effect around this period, marking the end of the treaty-port legal regime and “mixed residence” as foreigners came under Japanese law. Japan regained major legal sovereignty, but tariff-setting power was still not fully restored.
After 1899, Japan continued to trade under treaty-based limits that constrained how far it could raise or restructure tariffs. Japanese authorities treated customs policy as a central part of economic development, since tariffs affected industrial strategy and government revenue. This phase linked “free trade liberalism” pressures from major powers with Japan’s efforts to renegotiate from a position of greater equality.
By 1910–1911, Japan was negotiating a new commercial treaty with the United States that assumed tariffs would be set by national legislation or by special arrangements between the two governments. This signaled movement away from the older treaty system where tariff schedules were externally fixed. The talks were part of a broader push to remove the last major legal constraints on Japan’s trade policy.
In 1911, Japan’s long campaign to recover customs duty autonomy culminated in the full restoration of tariff-setting authority. Japan Customs summarizes this outcome as the complete restoration of autonomy in respect to customs duties in 1911, closing the final major economic limitation of the unequal-treaty era. The result reshaped Japan’s policy options: tariff changes could now be made through Japan’s own institutions rather than by foreign treaty control.
