Kose Corporation
Kose Corporation, founded in 1946 by Mamoru Kose, is a Japanese cosmetics company generating $2.4B in revenue, controlled by the founding family.
Kose Corporation
Founded by Mamoru Kose in Tokyo in 1946, Kose Corporation began as a cosmetics wholesaler before developing its own product lines. The Kose family retained a significant ownership stake after the company listed on the Tokyo Stock Exchange, with Kazutoshi Kobayashi serving as president and CEO as of 2025. The company generates revenue primarily through skincare brands including Cosme Decorte, Decorté, and Sekkisei, alongside makeup and suncare lines. Its geographic footprint centers on Japan, with growing distribution across China, Southeast Asia, and the United States. Kose has pursued brand acquisitions, including the 2022 purchase of US-based cosmetics brand Tarte for an undisclosed sum, to expand its portfolio and international reach. Kose reported approximately ¥355 billion ($2.4 billion) in net sales for the fiscal year ended March 2024, with an operating profit margin in the mid-teens. The firm maintains a manufacturing and R&D base in Japan and employs roughly 7,000 people worldwide. No additional family-office vehicles or philanthropic foundations are publicly disclosed. As a publicly traded entity with founding-family control, Kose differs from conventional family offices by channeling capital exclusively through its operating business. The family's wealth remains tied to the firm's equity rather than a separate investment pool, and dividend income provides liquidity for personal investment separate from corporate strategy.
