Which country is the home of the largest Japanese population outside of Japan?

Brazil is home to the largest Japanese population outside of Japan due to historical factors, such as the large-scale immigration of Japanese citizens to Brazil in the early 20th century. This immigration was primarily fueled by the need for labor in Brazil's agricultural sector. Additionally, the Brazilian government actively encouraged Japanese immigration during this time period. As a result, Brazil now boasts a significant Japanese community, which has integrated into Brazilian society while preserving their cultural heritage.
