Rohm

Owner rule under a listed company: Sato Kenichiro’s governance (1989)

Key decision·1989· Rohm — the full company history →

The power and the limits of personal gravity

The core of this governance was an asymmetry — closed to the outside, open on the inside — that reconciled delegation with a founder’s gravitational pull. Sato pushed day-to-day judgement down to the floor and declined even the customary courtesy calls on customers, while personally taking responsibility for the heavy decisions, such as whether an investment was right. His own voice, carried through the company newsletter and direct speech, and a dense familiarity that reached down to section-manager level, were the foundation that kept governance tight even as authority was handed away. Ownership of the stock and the appeal of the man together held the company as one, even after it went public.

Gravity that gathers around an individual, however, depends heavily on that individual. Sato’s rule rested on roughly 16% of the shares and on a personality that drew employees to him almost as a performer draws an audience. The rigour that extended even to the reception room was a strength and, at the same time, a personal quality no successor could simply inherit. In practice the structure gave way to collective leadership when a career employee took over in 2009, and the founder’s style of governance was not carried across intact. How to convert a founder’s gravitational pull into institutions — Sato’s solitary management reflects both the strength of dependence on a founder and the difficulty of succession that lies beyond it.
