The Next President of the United States: IV

Instead of going over the same points with USMC for the 3rd maybe 4th time, I’m going to ask a basic question here:

If you were take people from Central America say Honduras and dropped a few hundred thousand of them in Japan every year for 50 years, would Japan stay the same culturally?

Do you expect Hondurans to worship at Shinto temples, follow traditional Japanese ceremonies and adopt all the uniquely Japanese practises? Or would they largely stick to their own culture and build a mini Honduras in Japan?
