In this episode, Shigeki analyzes why “lightness” becomes the optimal survival strategy inside Japanese corporations. This is not a personal attack or a moral critique, but a structural explanation. In organizations where decisions change frequently, responsibility is blurred, and evaluation criteria are unclear, taking everything seriously can lead to exhaustion. Those who survive tend to detach emotions from words, tolerate contradictions, and switch positions quickly. What appears as superficiality is actually a functional adaptation. This episode explains why sincere, logically consistent people often burn out—and why incompatibility with such systems is not a personal failure, but a mismatch of environments.
