Hasekura Tsunenaga was a Japanese samurai and retainer of Date Masamune, the daimyō of Sendai.

In the years 1613 through 1620, Hasekura headed a diplomatic mission to the Vatican in Rome, traveling through New Spain (arriving in Acapulco and departing from Veracruz) and visiting various ports-of-call in Europe. This historic mission is called the Keichō Embassy, and follows the Tenshō embassy of 1582. On the return trip, Hasekura and his companions re-traced their route across Mexico in 1619, sailing from Acapulco for Manila, and then sailing north to Japan in 1620. He is conventionally considered the first Japanese ambassador in the Americas and in Europe.

Although Hasekura's embassy was cordially received in Europe, it happened at a time when Japan was moving toward the suppression of Christianity. European monarchs such as the King of Spain thus refused the trade agreements Hasekura had been seeking. Hasekura returned to Japan in 1620 and died of illness a year later, his embassy seemingly ending with few results in an increasingly isolationist Japan.

Japan's next embassy to Europe would only occur more than 200 years later, following two centuries of isolation, with the " First Japanese Embassy to Europe" in 1862.
