Date Masamune (1567–1636) was a famous Japanese samurai and daimyo who led the Date clan in the northeast and founded the city of Sendai. He is best known as a brave military leader and for the nickname Dokuganryū, or the One-Eyed Dragon of Ōshū, because he lost an eye in childhood. Some stories say he wore an eyepatch, but many portraits show him with both eyes.

Born Bontenmaru, Masamune was the eldest son of Date Terumune. He began his military career at age 14, helping his father fight the Sōma clan. When his father retired in 1584, Masamune became daimyo and expanded his lands by fighting rival clans in Mutsu and Dewa. He earned a fearsome reputation for bold campaigns and built up his base at Kurokawa Castle in Aizu.

In the 1590s, Masamune fought in Toyotomi Hideyoshi’s campaigns, including the invasions of Korea. Hideyoshi forced him to give up some lands in 1591, but Masamune later gained the Iwatesawa area and rebuilt Iwadeyama, turning it into a thriving center for the Date family. He also fought in regional wars, including against the Nihonmatsu and Ashina clans, strengthening his control in northern Honshu.

After Hideyoshi’s death, Masamune aligned with Tokugawa Ieyasu. He fought for the eastern army at the Battle of Sekigahara in 1600 and was rewarded with the Sendai Domain, a large and prosperous fief. In 1604 he moved with tens of thousands of followers to Sendai and began turning the area into a major city and power base. He expanded trade in the Tōhoku region and invited foreign visitors, supporting early contacts with Europe.

One notable achievement was funding the voyage of Hasekura Tsunenaga to Rome, an embassy that traveled to the Philippines, Mexico, Spain, and Italy. Some members stayed in Spain, and a group of descendants with the surname Japón still live there. Masamune also promoted religion in his domain, allowing missionaries for a time, though he eventually followed Tokugawa policy and restricted Christianity.

Masamune died in Edo (Tokyo) in 1636. His son, Date Tadamune, inherited Sendai. Masamune’s leadership helped make Sendai and the Tōhoku region powerful and prosperous for many years, and his legacy remains influential in Japanese history and culture.
