KOSÉ Corporation is a Tokyo-based cosmetics company engaged in the research, development, manufacture and sale of beauty and personal care products. Founded in 1946 by Kozaburo Kobayashi, the company has grown from a domestic shampoo producer into one of Japan’s leading cosmetics houses. KOSÉ’s product portfolio spans skincare, makeup, hair care and body care, positioning the company as a full-service beauty provider.
The company’s research and development efforts are centered on advanced skin science, combining traditional Japanese botanical ingredients with cutting-edge biotechnology. Flagship brands include Sekkisei, known for its whitening and hydration lines, and Cosme Decorté, a high-end skincare and color cosmetics range. In addition to branded products, KOSÉ supplies private-label and OEM cosmetics for international partners, leveraging its in-house manufacturing facilities to meet diverse quality and volume requirements.
KOSÉ serves a global customer base through a multi-channel distribution network encompassing department stores, specialty beauty retailers, e-commerce platforms and travel-retail outlets. While Japan remains its core market, the company has expanded across Asia, North America and Europe, with dedicated subsidiaries in China, Thailand and the United States. KOSÉ also collaborates with local distributors to tailor offerings to regional beauty trends and regulatory standards.
Leadership at KOSÉ has remained in the founding family since inception. Hideaki Kobayashi serves as chairman and chief executive officer, overseeing strategic initiatives such as digital marketing, sustainability and an accelerated product pipeline. Under his direction, KOSÉ is advancing eco-friendly packaging and cruelty-free formulations while investing in data-driven personalization to deepen consumer engagement in an increasingly competitive global beauty landscape.
