Tenshō 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).

They spent nine months visiting the Portuguese territories of Macau, Kochi, Madagascar and Goa on their way to Lisbon, where they arrived on 11 August 1584.

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").

[3] According to Derek Massarella, "Valignano conceived the idea of a book based on the boys’ travels, one that could also be used for teaching purposes in Jesuit colleges in Japan," but "despite its authors’ intentions," De Missione "made no lasting impact on Japanese perceptions of Europe.

Although he is generally believed to have abandoned Christianity, the discovery of what appear to be rosary beads in his grave in 2017 place this in some doubt.
