Millions of Lebanese did not go to Brazil. At best 500,000 people from Lebanon and Syria migrated to Brazil and they were overwhelmingly Christian. Michel Temer, current President of Brazil is of Christian Lebanese origin.

Brazil declared war on Japan in August 1942 and participated from Sept 1944 to May 1945, last 9 months in the war. Its forces fought in Italy. By Sept 1944 Japan was largely defeated and there was no pressing need to place Japanese Brazilians in concentration camps like the USA and Canada. Brazil did not suffer the terrible and unprovoked surprise attack on Hawaii which traumatized Americans.

Japanese Brazilians were subjected to a series of restrictive measures, requirement of safe conduct to travel the country, closure of 200 Japanese schools, thousands of Japanese immigrants arrested or expelled from Brazil on suspicion of espionage. https://en.wikipedia.org/wiki/Japanese_Brazilians#Prejudice_and_forced_assimilation
