Brazil, 12.2% of the first generation interviewed from Aliança reported they had studied the Portuguese language in Japan, and 26.8% said to have used it once on arrival in Brazil. Many of the Japanese immigrants took classes of Portuguese and learned about the history of Brazil before migrating to the country. In Fukuhaku only 7.7% of the people reported they had studied Portuguese in Japan, but 38.5% said they had contact with Portuguese once on arrival in Brazil. All the immigrants reported they spoke exclusively Japanese at home in the first years in Brazil. However, in 2003, the figure dropped to 58.5% in Aliança and 33.3% in Fukuhaku. This probably reflects that through contact with the younger generations of the family, who speak mostly Portuguese, many immigrants also began to speak Portuguese at home. The first Brazilian-born generation, the Nisei, alternate between the use of Portuguese and Japanese. Regarding the use of Japanese at home, 64.3% of Nisei informants from Aliança and 41.5% from Fukuhaku used Japanese when they were children. In comparison, only 14.3% of the third generation, Sansei, reported to speak Japanese at home when they were children. It reflects that the second generation was mostly educated by their Japanese parents using the Japanese language. On the other hand, the third generation did not have much contact with their grandparent's language, and most of them speak the national language of Brazil, Portuguese, as their mother tongue. Japanese Brazilians usually speak Japanese more often when they live along with a first generation relative. Those who do not live with a Japanese-born relative usually speak Portuguese more often. Japanese spoken in Brazil is usually a mix of different Japanese dialects, since the Japanese community in Brazil came from all regions of Japan, influenced by the Portuguese language. The high numbers of Brazilian immigrants returning from Japan will probably produce more Japanese speakers in Brazil. Distribution and population In 2008, IBGE published a book about the Japanese diaspora and it estimated that, as of 2000 there were 70,932 Japanese-born immigrants living in Brazil (compared to the 158,087 found in 1970). Of the Japanese, 51,445 lived in São Paulo. Most of the immigrants were over 60 years old, because the Japanese immigration to Brazil has ended since the mid-20th century. According to the IBGE, as of 2000, there were 1,435,490 people of Japanese descent in Brazil. The Japanese immigration was concentrated to
