From English Navigator to Samurai: The Journey of William Adams
The Life of William Adams
William Adams was born in 1564 in Gillingham, England. In 1600, as the navigator of the Dutch ship Liefde, he arrived in Japan after a harrowing journey across the Pacific. The ship made landfall in Bungo Province (present-day Oita Prefecture), where Adams and his surviving crewmates were taken into custody by the ruling authorities. At the time, Japan was in the final stages of the Warring States period, and Tokugawa Ieyasu was consolidating his power to unify the nation.
Relationship with Tokugawa Ieyasu
Adams quickly gained the trust of Tokugawa Ieyasu by sharing his knowledge of Western navigation, shipbuilding, and astronomy. His expertise was highly valued, and Ieyasu appointed him as a diplomatic advisor. In recognition of his service, Adams was granted a fief worth 250 koku and given the status of a samurai—an extraordinary honor for a foreigner. He took the Japanese name Miura Anjin, marking the beginning of his life as a samurai.

Japan’s First Western-Style Ship
Under Ieyasu’s orders, Adams led the construction of Japan’s first Western-style sailing ship in Ito, Izu. This ship, modeled after European designs, played a crucial role in Japan’s emerging maritime trade and strengthened its position in international commerce. His contribution to Japan’s naval development was an essential step toward the nation’s future interactions with the outside world.

Later Years and Legacy
Anjin remained in Japan for the rest of his life, continuing to serve as an advisor in diplomacy and trade. Unlike many foreign traders and missionaries of his time, he was not merely an observer but an active participant in shaping Japan’s foreign relations. He died in 1620 in Hirado, Nagasaki Prefecture, where his grave still stands today.
His legacy endures as a symbol of early cultural exchange between Japan and the West. His life story has been dramatized in the novel and television series Shōgun, though many aspects have been fictionalized. However, the reality of a man who came to Japan as a foreign sailor and rose to the ranks of the samurai is arguably even more fascinating than fiction.

A Lesser-Known Episode: The Forbidden Return
Despite his success in Japan, Adams was never allowed to return to England. Though he was granted land, a title, and a Japanese wife, he expressed a desire to reunite with his family back home. Ieyasu, however, saw him as too valuable to let go. In one remarkable episode, Adams was offered the opportunity to return to England aboard an English ship in 1613. Yet, he ultimately chose to remain in Japan, a decision that has puzzled historians for centuries. Was it loyalty to Ieyasu, attachment to his new life, or resignation to the impossibility of reclaiming his past? The answer remains a mystery, adding yet another layer of intrigue to his extraordinary life.
Fact vs. Fiction: Shōgun and the Real Miura Anjin
While Shōgun is inspired by Adams’ story, it takes creative liberties in its portrayal. His actual life was not one of constant warfare but rather one of diplomacy, adaptation, and trust-building within the shogunate. Yet, the core themes—a foreigner navigating the world of samurai, earning the respect of a powerful warlord, and leaving a lasting mark on Japan’s history—remain true to his incredible journey.
For those fascinated by Shōgun, exploring the real locations connected to Miura Anjin’s life offers a chance to step into history and experience the world that shaped both the man and the legend.
