Kobayashi Pharmaceutical Co., Ltd.

Kobayashi Pharmaceutical is a prominent Japanese manufacturer and marketer of over-the-counter (OTC) pharmaceuticals, quasi-drugs, dietary supplements, and daily household essentials. Founded in 1919 and headquartered in Osaka, the company is known for its niche-focused business model, maintaining leading market shares in numerous consumer healthcare categories in Japan. The company operates through domestic and international segments, with a strong presence in Asia and North America. Following a significant safety recall in 2024 related to its 'benikoji' (red yeast rice) supplements, the company has undertaken major organizational restructuring, including leadership changes and investments in AI-driven quality control and safety monitoring to restore consumer trust.
