When and for what reasons did the closure of Japan take place?

The closure of Japan is associated with the end of the civil war and the establishment of the Tokugawa shogunate in 1603. The power of the emperor was limited, and the shogun and the highest nobility did not like the appearance of Christians in the country as an instrument of influence on the Japanese affairs of Portugal and Spain (they were then in union). They also suggested that the country could suffer the fate of the Philippines, which became a colony of Spain.

The closure went as follows:

Christianity was banned in 1614.
In 1630, a ban on the import of books.
In 1638, a Catholic uprising was suppressed, and the Portuguese and Spaniards were expelled from the country.
By 1641, contacts with the outside world were limited to the port of Nagasaki, where a Dutch trading post operated.
