In Japanese management theory, it is said that when a company reaches maturity and its growth stagnates, it must once again invoke the "Sogyo Spirit" (the founding spirit) to break inertia and leap onto a new growth curve.

Therefore, Sogyo in this context is not the biological birth of the company (registration date), but the strategic rebirth. It is the moment when the company ceases to be what it was to become what it will be.
