Japanese immigration to Brazil in the early 20th century began officially in 1908 and formed the foundation of what is today the largest population of Japanese descent outside Japan (roughly 2 million Nikkei or people of Japanese ancestry).
Japan faced severe rural poverty, overpopulation relative to available land and infrastructure, high taxes (shifted to cash payments after the Meiji Restoration), and economic pressures following the Russo-Japanese War (1904–1905). Emigration was promoted as a solution to social tensions. The U.S. Gentlemen’s Agreement of 1907 restricted Japanese labor migration there, redirecting interest toward South America.
Brazil needed cheap agricultural labor after the abolition of slavery in 1888. Coffee plantations in São Paulo state expanded rapidly and faced shortages as European immigration (especially Italian) declined or faced restrictions (Italy banned subsidized emigration to Brazil around 1902). São Paulo’s government overrode earlier federal restrictions on Asian immigration (rooted in “whitening” policies and fears of a “yellow peril”) to secure workers. A 1907 contract between Ryo Mizuno of the Kokoku Shokumin Kaisha (Imperial Colonization/Emigration Company) and São Paulo authorities arranged for Japanese immigrants, initially targeting 3,000 people in family groups for farm work.
On June 18, 1908, the ship Kasato Maru arrived at the Port of Santos after a roughly 52-day voyage from Kobe, carrying 781 Japanese immigrants (primarily 165 families, with some singles and children). This marked the official beginning of continuous large-scale Japanese immigration; June 18 is commemorated as the National Day of Japanese Immigration in Brazil.
The immigrants were mostly destined for coffee fazendas (plantations) in the interior of São Paulo as colonos (contract laborers). Recruitment materials sometimes idealized coffee as a “tree of gold,” but conditions proved harsh: long hours, poor housing and pay, cultural and linguistic barriers, unfamiliar food and climate, and treatment residual from the slavery era. Many left plantations early; the first contingent was widely seen as struggling or a partial failure. A second group of about 906 (247 families) arrived on the Ryojun Maru in 1910.
Numbers grew slowly at first. Roughly 33,000 Japanese entered between 1908 and 1923, initially with subsidies from São Paulo and private Japanese agencies. By around 1914–1915 the Japanese population was estimated at about 10,000, with further family arrivals.
Many transitioned from contract labor to sharecropping, renting, or purchasing land (facilitated by railway expansion and land subdivision systems). Japanese agricultural colonies/settlements emerged in the São Paulo interior in the 1910s (examples include areas near present-day Cafelândia, Promissão/Lins, and others), focusing on coffee, cotton, potatoes, and other crops. Some immigrants moved to urban areas like São Paulo city (early presence in what became the Liberdade district from around 1912), establishing small businesses, hostels, and community institutions such as schools (e.g., Taisho Primary School in 1915).
Immigrants were required to come in family units to encourage permanence rather than temporary sojourning (dekasegi). Despite hardships, many endured, saved, adapted, and built self-reliant communities while maintaining Japanese language, education, and customs.
Immigration accelerated in the late 1910s (aided by World War I disrupting European flows) and especially from the mid-1920s, when the Japanese government took a stronger role with full subsidies and promotion to address overpopulation. Annual arrivals rose into the thousands and then tens of thousands. The prewar total reached around 189,000 by the early 1940s (with peaks in the late 1920s–early 1930s, such as over 24,000 in 1933). Most settled in São Paulo, with some expansion to Paraná and later experimental efforts in the Amazon.
By the early 1930s the Japanese population in Brazil approached or exceeded 100,000. Rising Brazilian nationalism under Getúlio Vargas led to restrictions (a 1934 immigration law with nationality quotas that heavily limited Japanese entries, plus further controls during the Estado Novo period), and immigration halted with World War II.
The early 20th-century wave established agricultural foundations, community institutions (schools, associations, presses), and the basis for later urban middle-class success among Nikkei. It occurred amid mutual economic needs but also prejudice, cultural distance, and adaptation challenges. Brazil ultimately received the bulk of Japanese emigration to Latin America, creating a distinct and enduring Japanese-Brazilian community.
