The Keichō Embassy: A Samurai’s Odyssey to the Heart of Christendom

In 1613, a historic maritime expedition departed from Japan, marking one of the most ambitious diplomatic endeavors of the early 17th century. The Keichō Embassy, led by the samurai Hasekura Tsunenaga and the Franciscan friar Luis Sotelo, set sail aboard the San Juan Batista. Their mission was twofold: to secure trade relations between Japan and New Spain (Mexico) and to advocate for the expansion of Catholic missionary work in the domain of their sponsor, the feudal lord Date Masamune.

The Geopolitical Context and Spanish Anxiety

At the time of the embassy's departure, Japan’s political landscape was shifting. While the Shogun Tokugawa Ieyasu initially maintained a pragmatic tolerance toward foreign trade, he was simultaneously growing wary of Christianity. By 1612, Ieyasu had issued an edict prohibiting the religion on Tokugawa lands. Despite this, the embassy proceeded, fueled by the hope that trade could still be established.

Upon arriving in Acapulco in 1614, the embassy encountered a Spanish imperial system that was deeply protective of its Pacific monopoly. As noted by Joshua Batts, the arrival of the San Juan Batista—a Japanese-built ship carrying merchants—served to "vindicate all of Spain’s anxieties." The Spanish crown, under King Philip III, had already been reluctant to grant trade access, fearing it would weaken the Manila-Acapulco corridor and invite piracy. The uninvited arrival of the Japanese only solidified these concerns.

Internal Strife and Diplomatic Failure

Internal conflicts further sabotaged the embassy’s objectives. A violent altercation between Japanese crew members and the Spanish explorer Sebastian Vizcaño led to scathing reports sent to the King, accusing the Japanese of theft and deceit. These reports, combined with news of intensifying Christian persecution in Japan, severely soured the Spanish court’s appetite for any formal agreements.

Even as Hasekura underwent a public baptism in Madrid in 1615, hoping to signal a genuine commitment to the faith, it proved to be a symbolic gesture rather than a political catalyst. The Spanish were, as the narrative suggests, "courteous to the Keichō embassy, but before long they were eager to be rid of them."

The Triumph and Tragedy of Rome

The embassy’s journey reached its zenith in Rome, where Hasekura and his entourage were received with great fanfare. Hasekura was even granted honorary citizenship of the "Eternal City." However, this triumph was purely symbolic. The Pope deferred all decision-making to the Spanish crown, which had already decided against the proposed trade routes and missionaries.

Unbeknownst to the embassy, their mission had been rendered obsolete before they even reached Europe. In February 1614, Ieyasu had issued a comprehensive expulsion edict, effectively banning Christianity in Japan. When Hasekura finally returned to Japan in 1620, he had little to show for his years of travel. His patron, Date Masamune, had fallen in line with the new anti-Christian policies, leaving Hasekura in a precarious position. While friar Luis Sotelo knowingly returned to Japan to face martyrdom—eventually being burned at the stake in 1624—Hasekura’s fate remained shrouded in mystery until his death in 1622, after which his story faded from history for centuries.

Conclusion

The Keichō Embassy stands as a testament to a brief moment of global ambition that was crushed by the hardening isolationism of Tokugawa Japan and the guarded imperialism of the Spanish crown. Despite the grand processions and the baptism of a samurai, the mission failed to achieve its tangible goals, illustrating the immense difficulty of bridging two vastly different worlds in the early modern era.

📖 Transcript

For two months, they were in the Pacific.
The samurai Hasakura Tsunenaga, the Franciscan friar Luis Sotelo and around 180 other Japanese, Portuguese and Spanish men, many of whom had never been in the open ocean before, had never experienced its great tempests and storms.
I guess there's a first time for everything.
The Kaichō Embassy, as it was called later, left Japan on October 28th 1613, heading east aboard the San Juan Batista.
On December 26th, almost two months later, they finally sighted land at Cape Mendocino, 200 miles north of what is now San Francisco.
If they stopped here, they did so briefly to restock, before continuing down the coast to their official destination Acapulco, a vital port city in what is modern day Mexico, but what was then a colony of Imperial Spain called New Spain.
