Missionaries were not reluctant to take military action if they considered it an effective way to Christianize Japan. They often associated military action against Japan with the conquest of China. They thought that well-trained Japanese soldiers who had experienced long civil wars would help their countries conquer China. For example, Alessandro Valignano said to the Philippine Governor that it was impossible to conquer Japan because the Japanese were very brave and always received military training but that Japan would benefit them when they would conquer China. Francisco Cabral also reported to the King of Spain that priests were able to send to China two or three thousand Japanese Christian soldiers who were brave and were expected to serve the king with little pay.
The Jesuits provided various kinds of support including military support to Kirishitan (Roman Catholic Christians) daimyo when they were threatened by non-Kirishitan daimyo. Most notable was their support of Omura Sumitada and Arima Harunobu, who fought against the anti-Catholic Ryuzoji clan. In the 1580s, Valignano believed in the effectiveness of military action and fortified Nagasaki and Mogi. In 1585,Gaspar Coelho asked the Spanish Philippines to send a fleet but the plan was rejected due to the shortness of its military capability. Christians Protasio Arima and Paulo Okamoto were named as principals in an assassination plot to murder the magistrate in charge of the Shogunate's most important port city of Nagasaki.
