In Japan, the term kirishitan (written in Edo period documents 吉利支丹, 切支丹, and in modern Japanese histories as キリシタン), from Portuguese cristão, referred to Roman Catholics in the 16th and 17th centuries before the religion was banned by the Tokugawa shogunate. Today, Christians are referred to in Standard Japanese as キリスト教徒, Kirisuto-kyōto or the English-derived term クリスチャン kurisuchan.
