Hawaii’s sugar plantations were built on the labor of successive waves of immigrant workers recruited from across the Pacific and beyond. Native Hawaiians were the first plantation workforce, but as the industry expanded through the second half of the 1800s, planters systematically brought in laborers from China, Japan, Portugal, Puerto Rico, Korea, the Philippines, and smaller numbers from Germany, Norway, Spain, Russia, and the South Pacific islands. Over roughly a century of large-scale sugar production, hundreds of thousands of workers from these groups shaped both the plantations and the multicultural society Hawaii is known for today.
Native Hawaiians: The First Workforce
When commercial sugar cultivation took root in the 1830s and 1840s, Native Hawaiians made up the largest portion of the plantation workforce. Records from Lihue Plantation on Kauai show a large majority of Hawaiian field workers, both men and women, during this early period. But Hawaiians generally preferred short contracts of three to six months, frustrating planters who wanted a stable, year-round labor supply.
Many Hawaiians avoided plantation work altogether when they could, earning cash by selling potatoes, wheat, coffee, goat skins, and other goods. It wasn’t until those alternative markets dried up in the 1870s that more Hawaiians found themselves with few options besides the fields. At the same time, the Native Hawaiian population was declining sharply from disease, and sugar irrigation was diverting water from taro farms, undermining the traditional food supply. These overlapping pressures pushed planters to look overseas for labor.
Chinese Workers: The First Immigrants
Chinese laborers were the first immigrant group recruited for plantation work. The earliest arrivals came under five-year contracts paying just $3.00 a month, with passage, food, clothing, and housing provided by the planter. Between 1850 and 1900, an estimated 46,000 Chinese came to Hawaii. Many fulfilled their contracts and then left the plantations to start small businesses, particularly in rice farming and retail trade in Honolulu and other towns. Their departure from the fields only intensified planters’ demand for new recruits.
Japanese Workers: The Largest Group
Of all the ethnic groups brought to Hawaii’s plantations, the Japanese were the most numerous. By the end of the 1800s, over 80,000 Japanese laborers had been imported. They became the backbone of the sugar industry for decades, filling the gap left as Chinese workers moved into other occupations. Japanese workers also became some of the earliest organizers of labor actions, including a major strike in 1909 that prompted planters to rethink their labor strategy and recruit heavily from new sources.
Portuguese, Puerto Ricans, and Koreans
Planters deliberately recruited from a wide range of countries, in part to prevent any single ethnic group from gaining enough numbers to effectively organize. Portuguese workers, many from the Azores and Madeira, occupied a unique position. The Hawaiian Sugar Planters’ Association promoted Portuguese workers to the role of luna (field foreman) while denying those supervisory positions to non-white workers, creating a deliberate racial hierarchy on the plantations.
Puerto Ricans arrived starting in 1900, with eleven migration expeditions taking place between 1900 and 1901 alone. Today roughly 25,000 Puerto Rican descendants live in Hawaii, about 2.3 percent of the state’s population. Korean laborers also arrived in the early 1900s, adding to the increasingly diverse plantation communities. Smaller groups of Germans, Norwegians, Spaniards, Russians, and South Sea Islanders rounded out the workforce at various points.
Filipino Sakadas: The Last Major Wave
After the 1909 Japanese strike, planters turned aggressively to the Philippines for labor. Starting in 1906 and continuing through the 1940s, the Hawaiian Sugar Planters’ Association recruited over 100,000 Filipino men, most of them from the Ilocos region in the northern Philippines. These workers were known as Sakadas. By the 1920s and 1930s, Filipinos were rapidly becoming the dominant labor force on the plantations, taking on the hardest field jobs as earlier immigrant groups moved into other industries or opened their own businesses. Filipino workers carried deep grievances over wages and working conditions, and they became central figures in later labor actions that eventually transformed the industry.
The Bango System
Regardless of ethnicity, plantation workers shared one dehumanizing experience: the bango system. Every laborer wore a metal identification tag, made of brass or aluminum, stamped with a number and hung on a chain around the neck. The shape of the tag typically indicated the worker’s race. Plantation managers kept all accounts under bango numbers, not employee names. Pay, deductions for rule violations, and purchases at the plantation store were all tracked by number. On payday, workers had to present their bango at the payroll desk. No tag, no pay.
The system was borrowed directly from the slave tags used in the American South before the Civil War. It reduced a diverse, multilingual workforce to numbered units, making it easier for managers to track productivity and enforce discipline across language barriers.
How Ethnic Diversity Shaped Hawaii
The plantation system’s strategy of importing one ethnic group after another was designed to keep workers divided and wages low. Planters pitted nationalities against each other, housing them in separate camps and paying different rates based on ethnicity. But over time, daily life in the fields and plantation towns had the opposite effect. Workers from different backgrounds shared food, language, and grievances. Alliances formed between Japanese, Chinese, Portuguese, Hawaiian, Filipino, Korean, and Puerto Rican laborers, and these cross-ethnic bonds became the foundation of what locals call “local culture,” the blended identity that defines Hawaii today.
The sugar plantations closed one by one through the late 20th century, with the last mill shutting down in 2016. But the descendants of plantation workers from a dozen countries remain the demographic core of the islands, a living record of the labor that built Hawaii’s modern economy.
