Shinzo Ohki arrived in Columbia City, Indiana with a simple observation: Americans had no idea what to do with soy sauce. By the 1930s, his factory was shipping 30,000 gallons a year across the region, turning a fermented condiment into the Midwest's unexpected economic engine.
Ohki's path to Columbia City was anything but direct. Born in Japan, he graduated from the local high school in 1907—a remarkable feat for a Japanese immigrant in that era—then returned to Japan to study food manufacturing and marry his childhood sweetheart. When he came back to America, he'd worked in Chicago handling Japanese imports before deciding to manufacture rather than simply distribute.
The Oriental Shoyu Factory, as he called it, faced an immediate problem: Midwesterners couldn't pronounce "shoyu." Rather than fight it, Ohki leaned in. He rebranded the sauce as "Show-You"—a name that felt familiar enough to say, foreign enough to intrigue. More importantly, he included recipe pamphlets with every bottle, showing customers exactly what to do with this mysterious dark liquid. Soy sauce went from curiosity to staple.

Ohki's success made him woven into Columbia City's fabric. His factory employed locals. His product synced perfectly with the region's thriving soybean farms. He wasn't just a businessman—he was essential infrastructure.
Then came World War II and the wave of anti-Japanese sentiment that swept across America. The federal government ordered Japanese Americans into internment camps. But Columbia City's residents and business leaders did something remarkable: they protected him. City officials and merchants wrote letters to the government arguing that Ohki was too important to the community to remove. Some accounts describe townspeople setting up informal guards around his home. In a nation gripped by fear and prejudice, this small Indiana city chose loyalty.
Ohki eventually retired in the 1960s, selling his company to one of Japan's emerging food conglomerates. His brand was absorbed into what became La Choy, the dominant soy sauce brand in American supermarkets for decades. The alleyway bearing his name remains in Columbia City, as does a scholarship at the high school where his American story began. It's a reminder that some of the most American success stories started with someone arriving with nothing but an idea—and a community willing to stand by it.
