The Meiji government formally organized an embassy headed by Iwakura Tomomi to pursue revision of the unequal treaties and to study Western political, legal, educational, and industrial institutions—linking diplomacy to state-building reforms at home.
The mission—officials, specialists, and students—sailed from Yokohama, beginning a nearly two-year circuit of the United States and Europe intended to inform Meiji-era political reforms and institutional modernization.
Landing in San Francisco marked the start of the U.S. leg, where the delegation investigated governance, education, industry, and infrastructure as models relevant to building a modern state in Japan.
After crossing the continent by rail, the delegation arrived in Washington, D.C., positioning the mission to present credentials and open formal talks on treaty revision with the U.S. government.
The mission visited the White House and held an audience with President Ulysses S. Grant, formally presenting diplomatic documents and signaling Japan’s intent to learn from Western institutions while seeking more equal diplomacy.
The first official meeting with the U.S. Secretary of State’s office began Japan’s attempt to extend and renegotiate treaty terms; the effort ultimately stalled in part because the delegation lacked sufficient plenipotentiary authority to conclude a new treaty.
After an unsuccessful treaty-revision effort in the United States, the delegation departed for Britain, where observation of industrial and governmental systems became a major practical focus for Meiji reformers.
Arriving at Liverpool, the delegation traveled onward to London and other industrial centers, studying institutions (Parliament, museums, transport) and modern industry—key inputs into Japan’s subsequent administrative and economic reforms.
At Windsor Castle, the delegation’s audience with Queen Victoria underscored Japan’s pursuit of recognition as a modern state and provided high-level diplomatic visibility during the mission’s European leg.
Leaving Britain for France, the mission continued its comparative study of Western states—tracking legal, administrative, and military institutions relevant to Meiji state formation even as treaty revision remained unresolved.
In Paris, Iwakura met Foreign Minister Charles de Rémusat, with discussions including treaty revision and related diplomatic concerns (including religious-freedom issues raised in negotiations), illustrating constraints Japan faced in altering treaty regimes.
In Berlin, the delegation was received by Kaiser Wilhelm I and met Chancellor Otto von Bismarck, while examining Prussian/German institutions—an influential reference point for later Meiji approaches to centralized governance and state power.
During May–June 1873 the delegation toured Italy (including major cities and institutions), extending its comparative survey of Western administration, military organization, industry, and culture as practical knowledge for modernization policy.
The mission arrived back in Yokohama, concluding a 12-country tour; its accumulated observations fed directly into Meiji-era debates and reforms in administration, education, industry, and diplomacy—even as treaty revision remained for later decades.
Kume Kunitake, the mission’s official diarist, published Tokumei Zenken Taishi Bei-Ō Kairan Jikki in five volumes, creating a foundational source that preserved the delegation’s detailed institutional observations and informed later historical understanding of Meiji reform priorities.
