Before any of the newer stories, there were the Kaingang, the indigenous nation the Portuguese colonizers called Coroados - the crowned ones - for the distinctive haircuts of their warriors. Their land stretched across what is now western Sao Paulo and parts of Parana, their lives organized around hunting grounds along the Rio do Peixe and the Aguapei. In 1852, the Imperial Government granted three Portuguese settlers the right to occupy those same lands, and what followed was the pattern repeated across Brazil: survey lines, pastures, coffee plantations, and the slow erosion of indigenous presence. In 1928, two landowners named Rodolfo and Luiz Miranda cleared 250 hectares of forest near Jacutinga Farm, divided the ground into lots, and began selling them. The town they founded was first called Otomania's Patrimony. It was renamed a few years later after senator Rodolfo Miranda's wife, Aretuza. Pompeia became a municipality by state law in 1938.

The railroad changed the geography. The Noroeste do Brasil line was built to connect Bauru, deep in Sao Paulo state, with the Bolivian border at Corumba in Mato Grosso do Sul - a west-bound steel corridor cut through country that had been, until recently, mostly forest. The clear-cutting that opened the right-of-way also opened the cerrado and woodland around Pompeia for coffee cultivation. Jacutinga Farm, owned by Rodolfo Lara Campos, led the conversion. By the 1920s the first coffee trees were flowering where old-growth had stood. The wealth that coffee generated was what drew the Portuguese, Italian, and Japanese immigrants whose descendants now make up most of the town.

Shunji Nishimura arrived from Japan at twenty-one years old in 1932 - one of the quarter-million Japanese immigrants who came to Brazil in the first half of the twentieth century, most of them to work coffee plantations in Sao Paulo state. He and his family began building agricultural maintenance equipment in 1948, when much of Brazilian farming still relied on hand tools and draft animals. The company they founded, Jacto, grew steadily through the 1950s and 1960s as mechanization spread across the Brazilian countryside. Their sprayers, applicators, and precision-agriculture equipment became standard on farms far beyond Sao Paulo. Today Jacto is among the top revenue generators in western Sao Paulo. The family also founded the Shunji Nishimura Foundation of Technology, which provides soil-testing services to farmers and has since 2013 partnered with the local technical college to offer degrees in Precision Agriculture Mechanization and Big Data in Agribusiness.

Drive through the center of Pompeia and you notice the bus shelters. Their roofs are not the squared steel canopies you find across most of the interior - they are curved, the corners swept upward in a gesture borrowed from Japanese temple architecture. The design speaks to a community that built something lasting out of a coffee-era diaspora. Traditional Japanese festivals still mark the calendar. The Shunji Nishimura Foundation operates alongside schools that ranked Pompeia among the 500 Brazilian cities offering the most educational opportunity. It is a small town - roughly 22,000 people across 784 square kilometers - that has turned immigration from a demographic fact into a civic identity.

The church, as in most paulista towns, is the other anchor. Pompeia belongs to the Roman Catholic Diocese of Marilia, and Catholicism remains the historical baseline. Evangelical Protestantism, led by the Assemblies of God - the largest evangelical denomination in Brazil - has grown alongside it. Christianity here is plural, the way it is across the country. But the town's self-understanding stays tied to the three waves that shaped it: Portuguese settlers of the imperial era, Italian coffee workers of the nineteenth century, and the Japanese families who arrived in the twentieth and stayed to build what nobody else was building. The name Pompeia sounds Italian. The bus shelters look Japanese. The coffee plantations that gave everyone a reason to come were Brazilian all along.
