I've worked for an American megacorp and the branch office of a Japanese company. The Japanese company felt a lot more humane on balance, though it doesn't express as well when I write it.

The Japanese company had some rituals were a bit weird, but harmless/charmingly quaint like mandatory volunteer days, keeping a copy of the founder's precepts on my desk for executive walkthroughs. They also had some bad tendencies, like praising employees for being there at 6AM/8PM. If something didn't work, they'd give it a bit of runway to see if it could pull through before cutting back. When there were layoffs, it was the whole division failing (each division competed with the others). It's hard to imagine what kind of political statements would have been offensive to that employer, it was just a neutral job. Really, the worst part was subpar compensation (and I still felt spoiled compared to Japanese coworkers).

My next job was at an American megacorp. The executives would give a holiday speech about "social responsibility" and how well we were doing, then layoff a factory. The employer was constantly involving themselves with US national politics, but employees were expected to refrain from having political opinions of their own.

You’re right and that’s intentional. Japanese companies don’t optimize for efficiently but for longevity. Sometimes those things go hand in hand. Sometimes they don’t.
