Launched as a private brand in 1980 to counter the increasingly brand-conscious consumer in Japan, MUJI offered beautifully designed, fairly priced, no-frills quality goods. The once modest private label brand with 40 products had expanded significantly by 2019 to more than 7,000 products with more than half its 975 stores outside its home market in Japan. It had even expanded into the service industry, opening hotels. President Matsuzaki of Ryohin Keikaku, MUJI's operating company, was charged with reorganizing the product portfolio and prioritizing new initiatives, tasks complicated by the absence of a clear definition of "MUJI-ness," the meaning of which had always been intentionally left open.

From the outside, DISCO-a Japan-based manufacturer of precision tools for semiconductor production devices-appeared to be a rather ordinary company that had achieved rather extraordinary success: it had simultaneously achieved 70% global market share, had lifted its profitability from 15% to 30% over the past seven years, and was consistently selected as a ""Best Workplace"" in Japan. The secret to DISCO's success, according to Sekiya, lay in its truly individualized management of human capital which they called the P-Will (Personal Will) system. P-Will was a proprietary managerial accounting system based on Will, a currency that enabled internal market transactions. At DISCO, every hour of labor and every good was associated with a price in Will. Employees were expected to act like independent business owners; they used the P-Will system to manage their own revenue contributions and business expenses in Will. Four times a year, the balances of individual P-Will accounts were converted to real currency and paid out as bonuses. In the last couple of years, about 10 companies, including other companies in the semiconductor industry, had visited Sekiya wanting to replicate DISCO's enviable success and introduce the P-Will system at their companies. However, none of these companies had actually implemented it. Seeing off another guest who had visited DISCO, Sekiya asked himself: Why don't other companies adopt the P-Will system? What were the conditions under which P-Will would work-and not work?

Hironobu Tsujiguchi, a Japanese chocolatier, had chosen an unusual path to success as a pastry chef. Instead of spending most of his time in his kitchen and focusing on one or two confectionery categories like most pastry chefs, he chose to work on diverse projects and leverage his reputation as a winning competitive chef to experiment with tastes and achieve business success. While Tsujiguchi enjoyed popularity and success in a broad array of projects, such as managing 10 brands and 26 shops across different categories, he also felt the need to reinvent his core confectionery business since not all stores of all his brands were thriving as he had wished. Equally central to the mission was the need to restructure the brand portfolio and operational model. Tsujiguchi asked himself: How can I orchestrate these efforts? Can I continue to rely on the diversification model that has led me to success so far, or should I be more focused? What should I continue, start, or stop doing to stay relevant?

Japan's corporate culture has traditionally prioritized the interests of stakeholders such as customers, employees, and suppliers over those of shareholders. After a decades-long economic slump, Japan's government has revitalized efforts to improve corporate governance in the country's public firms and to elevate public firms' incentives to engage with shareholders. Misaki Capital was founded in 2013 with a strategy of constructively engaging with portfolio firms, providing operational and financial advice to management to improve enterprise and shareholder value. This case asks students to consider the attractiveness of Japanese equities given recent reforms and to evaluate Misaki Capital's constructive investment approach. Students will evaluate how corporate governance in Japan is connected to public firms' market valuations and how elevating shareholders' de facto rights could improve firm performance and valuations. Which of Misaki's recommendations should Sangetsu Corporation pursue? How do they create value?
