Giovanni Battista Sidotti

Giovanni Battista Sidotti (1668 – 27 November 1714) was an Italian secular priest and Apostolic Missionary of the Pontifical Congregation of Propaganda Fide. During the Edo period, he entered Japan illegally and was arrested, whereupon he was confined until his death.

The Japanese politician and scholar Arai Hakuseki published the Seiyō Kibun based on his conversations with Sidotti.
