Abstract
YKK, the world’s leading fastening products manufacturer with a 40% global market share, exemplifies how a company can intertwine business excellence with social responsibility. Founded in 1934 by Tadao Yoshida, YKK built its strategy on the “Cycle of Goodness” philosophy, the belief that “no one prospers without rendering benefit to others.”
This case study explores how YKK’s vertically integrated model, ethical leadership, and innovation-driven approach enabled it to maintain quality, trust, and global competitiveness while advancing sustainability and inclusivity. It examines YKK’s business structure and how early decisions to internalize production and reinvest in communities forged a resilient global enterprise. It also evaluates YKK’s Corporate Social Responsibility (CSR) transformation from philosophical ethics to structured sustainability governance.
Findings reveal that YKK’s efforts, including renewable energy adoption, recycled-material zippers, and inclusive design innovations, embody authentic sustainability, though its lack of standardized ESG reporting remains a challenge. Ultimately, the case highlights YKK’s strategic dilemma: whether to expand into cost-sensitive markets to defend share against low-cost competitors or double down on innovation and sustainability to preserve brand integrity.
Designed as a problem-solving study, it invites learners to evaluate how YKK can sustain its founding philosophy while adapting to the fast-paced realities of global competition and evolving stakeholder expectations.
