Christian missionaries arrived in Japan with Francis Xavier and the Jesuits in the 1540s and briefly flourished, with over 100,000 converts, including many daimyōs in Kyushu. It soon met resistance from the highest office holders of Japan. Emperor Ōgimachi issued edicts to ban Catholicism in 1565 and 1568, but to little effect. Beginning in 1587, with imperial regent Toyotomi Hideyoshi's ban on Jesuit missionaries, Christianity was repressed as a threat to national unity.Jansen, p. 67 After the Tokugawa shogunate formally banned public Christianity in 1620, many Catholics went underground, becoming , while others were killed. Only after the Meiji Restoration was Christianity re-established in Japan.

Of the 95 Jesuits who worked in Japan up to 1600, 57 were Portuguese, 20 were Spaniards and 18 Italian.Ruiz-de-Medina, Father Juan G., Cultural Interactions in the Orient 30 years before Matteo Ricci.

Francisco Xavier,Saint Francis Xavier on Catholic Forum Cosme de Torres (a Jesuit priest) and Juan Fernandez were the first who arrived in Kagoshima with hopes to bring Catholicism to Japan.

The main goal was evangelism. But religion was also an integral part of the state and evangelization was seen as having both secular and spiritual benefits for both Portugal and Spain. Wherever these powers attempted to expand their territories or influence, missionaries would soon follow. By the Treaty of Tordesillas, the two powers divided the world between them into exclusive spheres of influence, trade and colonization. Although at the time of the demarcation, neither nation had any direct contact with Japan, that nation fell into the sphere of the Portuguese.

The countries disputed the attribution of Japan. Since neither could colonize it, the exclusive right to propagate Christianity in Japan meant the exclusive right to trade with Japan. Portuguese-sponsored Jesuits under Alessandro Valignano took the lead in proselytizing in Japan over the objection of the Spaniards. The fait accompli was approved in Pope Gregory XIII's papal bull of 1575, which decided that Japan belonged to the Portuguese diocese of Macau. In 1588, the diocese of Funai (the Funai Domain, centred on Nagasaki) was founded under Portuguese protection.

In rivalry with the Jesuits, Spanish-sponsored mendicant orders entered into Japan via Manila. While criticizing Jesuit activities, they actively lobbied the Pope. Their campaigns resulted in Pope Clement VIII's decree of 1600, which allowed Spanish friars to enter Japan via Portuguese India, and Pope Paul V's decree of 1608, which abolished the restrictions on the route. The Portuguese accused Spanish Jesuits of working for their homeland instead of their patron. The power struggle between Jesuits and mendicant orders caused a schism within the diocese of Funai. Furthermore, mendicant orders tried in vain to establish a diocese on the Tohoku region that was to be independent from the Portuguese one.

Religious rivalries between Catholics and Protestants reached Japan with the arrival of Dutch and English traders in the early 17th century. Although the English withdrew from their Japanese operations after a decade of trading under King James I due to lack of profitability, the Dutch continued to trade with Japan and became the only European country that maintained trade relations with Japan until the 19th century. Dutch traders frequently criticized the Catholic Church in Japan, which subsequently affected shogunate policies toward the kingdoms of Spain and Portugal.

Missionaries Francis Xavier

Francis Xavier was the first Jesuit to go to Japan as a missionary. In Portuguese Malacca in December 1547, Xavier met a Japanese man from Kagoshima named Anjirō. Anjirō had heard from Xavier in 1545 and had travelled from Kagoshima to Malacca with the purpose of meeting with him. Having been charged with murder, Anjirō had fled Japan. He told Xavier extensively about his former life and the customs and culture of his beloved homeland. Anjirō helped Xavier as a mediator and translator for the mission to Japan that now seemed much more possible. "I asked [Anjirō] whether the Japanese would become Christians if I went with him to this country, and he replied that they would not do so immediately, but would first ask me many questions and see what I knew. Above all, they would want to see whether my life corresponded with my teaching."

Xavier returned to India in January 1548. The next 15 months were occupied with various journeys and administrative measures in India. Then, due to displeasure at what he considered un-Christian life and manners on the part of the Portuguese which impeded missionary work, he left India and traveled to East Asia. He left Goa on 15 April 1549, stopped at Malacca and visited Canton. He was accompanied by Anjirō, two other Japanese men, the father Cosme de Torrès and Brother João Fernandes. He had taken with him presents for the "King of Japan" since he was intending to introduce himself as the Apostolic Nuncio.

Xavier reached Japan on 27 July 1549, with Anjirō and three other Jesuits, but it was not until 15 August that he went ashore at Kagoshima, the principal port of the province of Satsuma on the island of Kyūshū. As a representative of the Portuguese king, he was received in a friendly manner and was hosted by Anjirō's family until October 1550. From October to December 1550, he resided in Yamaguchi. Shortly before Christmas, he left for Kyoto but failed to meet with the Emperor. He returned to Yamaguchi in March 1551, where he was permitted to preach by the daimyō of the province. However, lacking fluency in the Japanese language, he had to limit himself to reading aloud a Japanese translation of a catechism.

The Japanese people were not easily converted; many of the people were already Buddhist or Shinto. Francis tried to combat the disposition of some of the Japanese that a God who had created everything, including evil, could not be good. The concept of Hell was also a struggle; the Japanese were bothered by the idea of their ancestors living in Hell. Despite Francis' different religion, he felt that they were good people, and could be converted.Ellis, Robert Richmond.

Xavier brought with him paintings of the Madonna and the Madonna and Child. These paintings were used to help teach the Japanese about Christianity. There was a huge language barrier as Japanese was unlike other languages the missionaries had previously encountered. For a long time Francis struggled to learn the language. Artwork continued to play a role in Francis' teachings in Asia.

Xavier was welcomed by the Shingon monks since he used the word Dainichi for the Christian God; attempting to adapt the concept to local traditions. As Xavier learned more about the religious nuances of the word, he changed to Deusu from the Latin and Portuguese Deus. The monks later realized that Xavier was preaching a rival religion and grew more aggressive towards his attempts at conversion.

When Xavier arrived in Japan, the country was embroiled in a nationwide civil war. Neither the emperor nor the Ashikaga shōgun could exercise power over the nation. At first, Xavier planned to gain permission for building a mission from the emperor but was disappointed with the devastation of the imperial residence. The Jesuits approached daimyō in southwestern Japan and succeeded in converting some of them. One reason for their conversion may have been the Portuguese trade in which the Jesuits acted as brokers. The Jesuits recognized this and approached local rulers with offers of trade and exotic gifts.

The Jesuits believed that it was most effective to seek to influence people in power and to pass the religion downward to the commoners. At the least, they needed to gain permission from local rulers to propagate Catholicism within their domains. Indeed, as feudal lords converted to Catholicism, the number of believers within their territories also drastically increased. After the edict banning Christianity, there were communities that kept practicing Catholicism without any contact with the Church until missionaries were able to return much later.

When Xavier disembarked in Kagoshima, the principal chiefs of the two branches of the Shimazu family, Sanehisa and Katsuhisa, were warring for the sovereignty of their lands. Katsuhisa adopted Takahisa Shimazu, who in 1542 was accepted as head of the clan, having previously received the Portuguese merchants on Tanegashima Island and learned about the use of firearms. Later, he met Xavier himself at the castle of Uchiujijo and permitted the conversion of his vassals.

Having a religious background, Takahisa showed himself to be benevolent and already allowed freedom of worship, but did not help the missionaries or favor their church. Failing to find a way to the centre of affairs, the court of the Emperor, Xavier soon tired and left to Yamaguchi, thus beginning the Yamaguchi period.Lopez-Gay, St Francis Xavier and the Shimazu Family, Bulletin of Portuguese/Japanese Studies, Uni. Nova de Lisboa, Portugal 2003 Xavier stayed in Yamaguchi for two months on his way to an abortive audience with the Emperor in Kyoto. Yamaguchi was a prosperous and refined city, and its leaders, the Ouchi family, were aware that Xavier's journey to Japan had begun after the completion of his mission in India.

They took Catholicism for some sort of new sect of Buddhism, and were curious to know of the priest's doctrine. Tolerant but shrewd, their eyes less on baptism than the Portuguese cargoes from Macau, they granted the Jesuit permission to preach. The uncompromising Xavier took to the streets of the city denouncing, among other things, infanticide, idolatry, and homosexuality (the last being widely accepted at the time). Misunderstandings were inevitable.

The Jesuits attempted to expand their activity to Kyoto and the surrounding regions. In 1559, Gaspar Vilela obtained permission from Ashikaga Yoshiteru to teach Christianity. This license was the same as those given to Buddhist temples, so special treatment cannot be confirmed regarding the Jesuits. On the other hand, Emperor Ōgimachi issued edicts to ban Catholicism in 1565 and 1568. The orders of the Emperor and the shōgun made little difference.

Christians refer positively to Oda Nobunaga, who died in the middle of the unification of Japan. He favored the Jesuit missionary Luís Fróis and generally tolerated Christianity. But overall, he undertook no remarkable policies toward Catholicism. Actually, Catholic power in his domain was trivial because he did not conquer western Japan, where the Jesuits were based.

With the passage of time, Xavier's sojourn in Japan could be considered somewhat fruitful as attested by congregations established in Hirado, Yamaguchi and Bungo. Xavier worked for more than two years in Japan and saw his successor-Jesuits established. He then decided to return to India.

For 45 years, the Jesuits were the only Christian missionaries in Asia, and then the Franciscans began proselytizing as well.
