The Tenshō embassy (Japanese: 天正の使節, named after the Tenshō Era in which the embassy took place) was an embassy sent by the Japanese Christian Lord Ōtomo Sōrin to the Pope and the kings of Europe in 1582. The embassy was led by Mancio Itō (伊東 マンショ Itō Mansho, 1570–1612), a Japanese nobleman, who was the first official Japanese emissary to Europe. Embassy The idea of sending a Japanese embassy to Europe was originally conceived by the Jesuit Alessandro Valignano, and sponsored by the three Kirishitan daimyōs Ōmura Sumitada (1533–1587), Ōtomo Sōrin (1530–1587), and Arima Harunobu (1567–1612). Mancio Itō was chosen to act as a spokesman for the group dispatched by Ōtomo Sōrin, who was daimyō of the Bungo Province on Kyūshū and a close relative of Mancio's father; Shurinosuke Itō. On February 20, 1582, Mancio Itō left Nagasaki in company with three other noblemen: Miguel Chijiwa (千々石 ミゲル Chijiwa Migeru) Julião Nakaura (中浦 ジュリアン Nakaura Jurian) Martinho Hara (原 マルチノ Hara Maruchino) They were accompanied by two servants, their tutor and interpreter Diogo de Mesquita, and their mentor Valignano, who only accompanied them as far as Goa in Portuguese India, where he was to take up new responsibilities. On their way to Lisbon, where they arrived in August 1584, they spent nine months visiting the Portuguese territories of Macau, Kochi, Dubai, Madagascar and Goa.

In Spain they visited Talavera de la Reina, Toledo, Madrid, where they met with Philip II who was king of Spain and Portugal. They visit El Escorial monastery, the Alcalá University, Murcia and Alicante. In Rome, Mancio Itō became an honorary citizen and taken into the ranks of European nobility with the title Cavaliere di Speron d'oro ("Knight of the Golden Spur"). During their stay in Europe, they met with King Philip II of Spain, Francesco I de' Medici, Grand Duke of Tuscany, Pope Gregory XIII, and his successor Pope Sixtus V. The ambassadors arrived back in Japan on July 21, 1590. On their eight-year-long voyage they had been instructed to take notes. These notes provided the basis for the De Missione Legatorum Iaponensium ad Romanam Curiam ("The Mission of the Japanese Legates to the Roman Curia"), a Macau-based writing by Jesuit Duarte de Sande published in 1590.
