Sir John Bowring, who negotiated the treaty of 1855, was able to secure the principle of extra-territoriality for British subjects, permission to build churches and exemption of all duty for import of opium.

In the first place, the missionary brought with him an attitude of moral superiority and a belief in his own exclusive righteousness …… Secondly, from the time of the Portuguese to the end of the Second World War, the association of Christian Missionary work with aggressive imperialism introduced political complications into Christian work…… Inevitably, national sentiment looked upon Missionary activity as inimical to the country's interests and native Christians as secondary barbarians.

Jacques Spex had explained to Ieyasu the methods of Spain and Portugal and in 1612 Henrick Brower presented to the Shogun a memorandum on Spanish and Portuguese methods of conquest. In the time of the second Tokugawa Shogun (Hidetada) the European nations were themselves denouncing each other's imperialist intentions. The Japanese converts had, as elsewhere, shown that their sympathies were with their foreign mentors and for this they had to pay a very heavy price. The Christian rebellion of 1637 in Shembara disclosed this danger to the Shogun. It took a considerable army and a costly campaign to put down the revolt which was said to have received support from the Portuguese. The Japanese were also fully informed of the activities of the Portuguese, the Dutch, the Spaniards and the English in the islands of the Pacific especially in the Philippines, the Moluccas and Java ‑ and these had taught them the necessity of dealing with the foreigners firmly and of denying them an opportunity to gain a foothold on Japanese territory. In 1615 the Japanese sent a special spy to the southern regions to report on the activities of the Europeans there. They were strengthened by the information that reached them in 1622 of a Spanish plan to invade Japan itself. By the beginning of the seventeenth century Spain had consolidated her position in the Philippines, where she maintained a considerable naval force. Japan was the only area in the Pacific which Spain could attack without interfering with Portuguese claims or the Papal distribution of the world which in her own interests she was bound to uphold. It seemed natural to the Spaniards that they should undertake this conquest. The reaction of the Shogunate was sharp and decisive. All Spaniards in Japan were ordered to be deported, the firm policy of eliminating the converts was put into effect and a few years later the country was closed to the Western nations.
