This case study examines the remarkable evolution of Daikin Industries, a company that demonstrated resilience and innovation over nearly a century. Founded in 1924 by Akira Yamada in Osaka, Japan, Daikin originally focused on manufacturing aircraft components. However, the company pivoted towards refrigeration technology in response to emerging market demands, notably during Japan’s post-World War II economic boom. By leveraging R&D in fluorocarbons and innovative cooling technologies, Daikin established itself as a leader in the air conditioning sector. The case highlights key leadership eras, notably the transformative periods under Noriyuki Inoue. Under Inoue’s stewardship, the company emphasized execution capabilities, prioritizing operational excellence alongside technological advancement. His leadership drove Daikin’s globalization strategy, enabling the company to become the second-largest fluorocarbon producer globally and the foremost player in the air conditioning market. As Daikin approaches its 100th anniversary, it faces contemporary challenges such as climate change and increasing consumer demands for energy-efficient products. The company’s commitment to innovation remains pivotal as it seeks to balance profitability with environmental responsibility. This case prompts discussion on Daikin’s strategic responses to evolving market conditions and the importance of leadership in sustaining growth.
