Japanese Brazilians (Japanese: 日系ブラジル人, Hepburn: Nikkei Burajiru-jin; Portuguese: Nipo-brasileiros, [ˌnipobɾaziˈle(j)ɾus]) are Brazilian citizens who are nationals or naturals of Japanese ancestry or Japanese immigrants living in Brazil or Japanese people of Brazilian ancestry. Japanese immigration to Brazil peaked between 1908 and 1960, with the highest concentration between 1926 and 1935. In 2022, Japan's Ministry of Foreign Affairs stated that there were 2 million Japanese descendants in Brazil, making it the country with the largest population of Japanese origin outside Japan. However, in terms of Japanese citizens, Brazil ranked seventh in 2023, with 46,900 Japanese citizens. Most of the Japanese-descendant population in Brazil has been living in the country for three or more generations and most only hold Brazilian citizenship. Nikkei is the term used to refer to Japanese people and their descendants.
Japanese immigration to Brazil officially began on June 18, 1908, when the ship Kasato Maru docked at Porto de Santos, bringing 781 Japanese workers to the coffee plantations in the São Paulo state countryside. For this reason, June 18 was established as the national day of Japanese immigration. Immigration to Brazil ceased by 1973, with the arrival of the last immigrant ship, the Nippon Maru. Between 1908 and 1963, 242,171 Japanese immigrants arrived in Brazil, making them the fifth-largest immigrant group after Portuguese, Italian, Spanish, and German immigrants. Currently, most Japanese Brazilians live in the states of São Paulo and Paraná.
