Lion

The Pentadecan falsified-data scandal and President Kobayashi Atsushi’s reckoning (1989)

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

What a scandal and a self-diagnosis left behind

What stands out here is that the president spoke less about handling the incident than about the ground that had produced it, and did so on a long time horizon. Rather than confining the falsification to one employee’s deviation, he tied it to deeper management problems: an organization swollen by the 1980 merger, an expansion plan in which growth targets had run out ahead of everything else, and a sense of crisis that had never penetrated the shop floor. He avoided the legible resolution of resignation in favour of analysing the cause and preventing a recurrence.

That reckoning did not, however, convert into results within a few years. Several more passed between the pledge to become a company highly attuned to its market and any visible improvement in profitability. The weight of the affair lies in the fact that a scandal over a single hair-growth product became the occasion to re-examine a management style still unsettled almost a decade after the merger. Reconsidering the company’s constitution only once a crisis is at the door is a pattern that appears to have cast a shadow over Lion’s management thereafter.
