The case in brief
Yasujiro Tsutsumi, a farmer’s eldest son, founded the Seibu Group. His third son, Yoshiaki, took over the railway group while his half-brother Seiji took the retail group (Seibu Department Stores). Yoshiaki, an autocrat with strong business acumen, expanded Kokudo and Seibu Railway from the 1960s into Prince Hotels, ski resorts, skating rinks and suburban housing.
He kept his father’s methods: aggressive tax minimisation and a holding-company structure (Kokudo) to secure family control. To obey the family code — never sell a majority of shares or be taken over — while avoiding delisting, he placed shares in employees’ names and misreported ownership. He was arrested for falsifying securities reports and insider trading, the family’s equity ties to the group were dissolved, and control passed to a third party outside the family.
An outside CEO, Takashi Goto, sent from Mizuho Corporate Bank, led reforms: a new pure holding company (Seibu Holdings), outside capital through a third-party allotment of shares, and a group-wide code of ethics and compliance system.

Analysis through module theory
Socioemotional wealth (Gómez-Mejía et al., 2007)
The family code put control and identity above everything else. Preserving that non-financial wealth drove the concealment of shareholdings that ultimately cost the family all its equity.
Agency theory (Kara et al., 2006)
The case lists “actions taken solely in the interest of one family” and appropriation of the company. The controlling family acted against minority shareholders and the stock market by misreporting ownership and trading on inside information.
Succession and governance
The successor copied his father’s autocratic methods, producing managers and employees who simply awaited orders. The roles of family, board and executives were unclear, and the firm neglected reform and innovation, clinging to past success models.
Family Business Secrets of Success model
Seibu was weak in several categories at once — Ethics and Adaptability, Responsible Ownership, and Separation of Issues and Governance Structures — and the model holds that the more categories in which a firm fails, the more vulnerable it is.
Discussion questions
- 1.What went wrong at Seibu, and which failure was most decisive?
- 2.Was Yasujiro’s control system a sound strategy in its time but a liability for the next generation?
- 3.What does the case suggest about choosing and preparing a successor?
Takeaways
- Founders’ emotional attachment can lead them to choose unsuitable successors and cling to power.
- Hand the work to a team around the successor, not to one person alone.
- Control without ethics, compliance and clear governance destroys the legacy it tries to protect.
