How did the penetration of Europeans into the country affect the development of Japan?

The first Europeans appeared in Japan in the 1530s, they were the Portuguese, they sailed there through the warm seas from the south. First around Africa to India, and then through Melacca and the coast of southern China to the north.

From the Portuguese, the Japanese borrowed Christianity (Catholicism), which was banned by the shogun by 1640, as well as some military novelties (muskets, ships, guns).

The period from 1640 to 1854 was a time of greatest isolation, since the 1850s and especially since 1868 Japan was opened, she quickly modernized on the European model, created a fleet, an army, a parliament and a constitution.
