In this episode, I explore why so many brilliant communicators in Japan’s manufacturing world—people full of humor, insight, and real experience—never appear on the internet. Their silence is not due to inability, but to culture: a corporate faith that treats knowledge as company property and praises loyalty through quiet obedience. Speaking out feels like betrayal. Yet, I see expression as a new form of loyalty—one rooted in honesty, respect, and responsibility. By turning the “world of oil and iron” into voice, I aim to preserve the living spirit of Japan’s craftsmen before it fades into silence.
