Kobayashi Sei

Kobayashi Pharmaceutical is a prominent Japanese consumer healthcare company that develops, manufactures, and markets a wide range of over-the-counter (OTC) medicines, health supplements, and household products. Founded in 1886 and headquartered in Osaka, the company is renowned for its "niche" strategy, focusing on innovative products that address specific, often overlooked consumer needs. Its flagship brands include Ammeltz (topical analgesic), Koolfever (cooling gel sheets), and Naicitol (weight management). The company operates globally, with a significant presence in Asia and the United States, focusing on improving quality of life through accessible healthcare and hygiene products. In 2024, the company underwent a major leadership restructuring and governance overhaul following a significant product safety crisis involving its red yeast rice supplements.
