I'll preface this by saying there are lots of other factors at play, but here's an interesting one I can speak to personally:
Car culture. We're a very car-centric society, and the Japanese auto makers have been a part everyday life to 3 full generations of Americans now. Even most Baby Boomers are too young to remember a world without Honda or Toyota. Across all age groups, a lot more Americans grew up with a fondness for their family's Toyota than their family's Hyundai.
I grew up in middle America. Both my grandfathers were "GM Men" if you will. Partly by vocation, partly by culture. On both sides of my family, every car was either a Chevy or a Buick. When my folks bought a Honda in 2007, it was treated like a scandal. But yknow what? Now one of my cousins has a Hyundai, and nobody batted an eye. Things are changing, even for the "raise hell praise Dale" crowd.
Japan's car makers, and their other industrials have a 40-year head start on embedding themselves in the American zeitgeist. Sony, Panasonic, Canon, Yamaha, they've all been here a really long time. They're loved because they're familiar. That's a bias, and I think that bias colors the way we talk about east Asian businesses more broadly.
