"Christian missionaries" group concerned the Tokugawa shoguns enough to limit the contacts between Japan and Europe.
<u>Explanation:</u>
Tokugawa Ieyasu, who led the nation after Hideyoshi's death, initially tolerated Christian faith, but eventually abolished Christianity throughout the country, to reinforce the base for the family-led Tokugawa regime.
Finally, in 1614, he decided to ban Catholicism and, in the mid-17th century, requested that all Foreign missionaries be expelled and that all converts be executed. That signaled the end of accessible, Japanese Christianity. Tokugawa ruled nation for half a century and pressurized Christian Japanese to direct towards Buddhism.
