but thousands of Japanese were pressured into moving voluntarily. About 10,000 Macanese and 3,000 Japanese were moved to Manila. The Catholic remnant in Japan were driven underground, and its members became known as the "Hidden Christians". Some priests remained in Japan illegally, including 18 Jesuits, seven Franciscans, seven Dominicans, one Augustinian, five seculars and an unknown number of Jesuit irmao and dojuku. Since this time corresponds to the Thirty Years' War between Catholics and Protestants in Germany, it is possible that the checking of Catholic power in Europe reduced the flow of funds to the Catholic missions in Japan, which could be why they failed at this time and not before. During the Edo period, the Kakure Kirishitan kept their faith. Biblical phrases or prayers were transferred orally from parent to child, and secret posts (mizukata) were assigned in their underground community to baptize their children, all while regional governments continuously operated fumi-e to expose Christians. Rediscovery and return Japan was forced to open to foreign interaction by Matthew Perry in 1853. It became possible for foreigners to live in Japan with the Harris Treaty in 1858. Many Christian clergymen were sent from Catholic, Protestant and Orthodox churches, though proselytizing was still banned. In 1865, some of the Japanese who lived in Urakami village near Nagasaki visited the new Ōura Church which had been built by the Paris Foreign Missions Society (Missions étrangères de Paris) barely a month before. A female member of the group spoke to a French priest, Bernard Petitjean, and confessed that their families had kept the Kirishitan faith. Those Kirishitan wanted to see the statue of St. Mary with their own eyes, and to confirm that the priest was single and truly came from the pope in Rome. After this interview, many Kirishitan thronged toward Petitjean. He investigated their underground organizations and discovered that they had kept the rite of baptism and the liturgical years without European priests for nearly 250 years. Petitjean's report surprised the Christian world; Pope Pius IX called it a miracle. The Edo Shogunate's edicts banning Christianity were still on the books, however, and thus the religion continued to be persecuted up to 1867, the last year of its rule. Robert Bruce Van Valkenburgh, the American minister-resident in Japan, privately complained of this persecution to the Nagasaki magistrates, though little action was taken to stop it. The succeeding government under Emperor Meiji,
