1.
missionary
A person sent to propagate a religion, especially Christianity, in a foreign country or region. Historically significant in the context of European contact with Japan.
Common patterns
宣教 (proselytization, missionary work) + 師 (master, teacher, practitioner).
Cultural note
宣教師 is closely associated with the history of Christianity in Japan. The first European missionaries arrived in the 16th century during the 戦国時代 (Warring States period). The subsequent 禁教令 (ban on Christianity) during the 江戸時代 is a major historical topic.
